Soundproofing Insulation – What, Where, Why, How

Insulation for the home can make a big difference. While it is essential to have as part of a home, different types make sense for different situations.

This guide is meant to help people understand the different types of insulation materials, as well as the value each provides. Other information such as handling different variables, and even the health impact of insulation, also makes sense.

No one wants to be in a tough situation later on after spending so much time and energy getting things set up. By the end of this guide, homeowners can have a better idea of the best insulation for them.

Different Insulation Materials

All in all, there are four general types of home insulation materials used at this time. There are different qualities to these materials, making sure that there is an option for just about every situation.

Fiberglass Insulation

Fiberglass Insulation For Soundproofing

Fiberglass insulation is made from glass cullet, as well as other materials that are put into fibers that look much like wool. When a person purchases fiberglass insulation, it comes in a few different forms such as batts, rolls, or loose-fill.

Fiberglass is usually found in places such as attics and crawl spaces, as well as basements and even floors.

A lot of people believe that it takes a decent amount of time and attention to install fiberglass installation just right. It is important to follow guidelines so that there is very little chance of having to redo anything in particular.

When done the right way, fiberglass will last a long time, provide any additional benefits are detail below, and allow people to feel like they are getting excellent value for the price.

Mineral Wool Insulation

Mineral Wool Insulation For Soundproofing

This insulation option, also known as rock wool insulation or slag wool insulation, comes from a combination of rock, blast furnace slag, and additional raw materials.

These materials are melted and spun into different fibers to look a lot like wool. Like fiberglass, it also comes in batts, rolls, or fairly loose-fill forms.

A lot of the locations this insulation is found in is where people others use fiberglass as well. The two options are pretty interchangeable in a lot of different attributes, which is why they have so much overlap.

There are two different types of mineral wool insulation that people tend to gravitate towards. Slag wool is a little bit different in they are only about 15% of the content is recycled.

When looking at mineral wool, as much as 90% of the content can be recycled. There are a few other differences, but people like it because it is pretty easy to install and get right the first time.

There might be some minor challenges if things are not done exactly as they should, but most people will figure it out if they have professionals who can take care of everything.

Spray Foam Insulation

Spray Foam Insulation For Soundproofing

This is a chemical base insulation that people create on-site to get ready for certain areas around the home. Most of the time, a sprayer is used to put this insulation in attics and other wall cavities.

With spray foam, there are two types of insulation, as people will go with open-cell foam or closed-cell foam.

The challenge of spray foam during the installation process is that it needs to be the right time and atmosphere to make it work properly. Things such as temperature, humidity, and the overall cleanliness of the area make a difference.

It is also challenging for the installers to see any particular gaps during the application process to get everything evenly applied. There are times when the first run might not work out exactly as planned, and more effort needs to be put into the situation.

Cellulose insulation

Cellulose Insulation

Created by using cellulose fibers from paper or wood, this is a great installation option to resist fire. Creating this insulation means using binders in some situations, and avoiding them in others.

There is still a lot to learn about cellulose insulation, which is why it might not be quite as popular as more traditional methods. There is enough promise to leave people intrigued, but it might take a while for cellulose to take off.

Before You Begin Your Insulation Project

Still unsure on installation options available? There are a lot of questions people might have before making any investment. A look at some of these answers can make the decision slightly easier.

The insulation material is not going to make too much of a difference with energy savings. However, there are a few factors that do make a difference.

People need to make sure that they keep these factors in mind so that they are getting the most out of their insulation.

Proper Installation

Do not cut corners and have subpar installation with insulation. It can be extremely frustrating for people who do not get the little things done correctly. It will need to be redone, and it can become pretty costly to handle all that.

Most of the time, the only way to get the correct insulation is to make sure that it is installed properly by professionals.

They will know exactly what is needed, they can usually get things done quickly, and it is not all that expensive compared to all of the hassle that it might take to make corrections. Even if that means starting a new project over from scratch, it might be worth it in the end.

Considering R-Value

The R-value of insulation material is going to explain how well it can resist heat flow. If it has a high R-value, it provides great insulating power.

This is a better way to measure everything instead of the material itself. All our values are created equally if everything is done correctly during the installation process.

Air Sealing

This goes along with installation in general, but air-sealing is extremely important and making sure that everything works properly.

There are a lot of people who might get most of the installation process done correctly, but there is just a little bit of air seeping through. It might not seem like that big of a deal at first, but it becomes more and more of an issue as time goes on.

What Insulation Has the Best Quality Control?


From a quality perspective, fiberglass and mineral wool insulation is usually the way to go. They are both produced in manufacturing facilities with a lot of quality controls in place to ensure that it’s done properly.

These companies know exactly what is needed to provide proper installation, and they must live up to standards before ever shipping out.

Cellulose insulation is pretty high-quality as well, but the process to apply this insulation is not as standardized as fiberglass in the wall.

There is also the thought that the ability to be fire resistant wears off as time goes on. People need to stay on top of everything so that they are fully aware of what to expect in that regard.

Finally, spray foam insulation might be the most unpredictable as far as quality is concerned. That is because everything is manufactured on site, and a professional needs to know what they are doing to make it great.

If done incorrectly, spray foam insulation can fail to live up to expectations. This can be anything from mixing the chemicals at home incorrectly, using old chemicals, not storing chemicals properly, and even the air quality around not being the best. It is a very delicate procedure, so keep that in mind.

Can Insulation Help With Acoustic Performance?

There is a rating system for insulation materials when it comes to acoustic performance, noise reduction, and sound interference.

For those who really care about the type of sound that they hear around the home, it is important to pay attention to these numbers and take the right action.

The Noise Reduction Coefficient is on a scale going from 0 to 1, with a higher number being better. There is also the Sound Transmission Coefficient, which is based on how much noise transmission goes through a particular barrier. The higher the STC number, the better it performs.

Fiberglass and mineral wool insulation rate the highest, as they both have a 1.0 NRC, as well as around 43 STC. Spray foam and cellulose insulation are a little lower with an NRC a .75, and spray foam has an STC of around 37 to 39.

Does Insulation Have Safety and Health Concerns?

In the past, there have been a lot of concerns about health issues with fiberglass and mineral wool. In particular, there was formaldehyde in a lot of insulation in the past, and people complained about skin irritation as well as respiratory issues around it. Things have evolved where it is much safer these days, and a lot of people have no problems whatsoever.

The good news is that these installations are now assessed regularly so that if there are any health issues, there will be ways to sniff things out.

The Consumer Product Safety Commission has officially labeled fiberglass insulation as having very little impact on formaldehyde levels in a home.

Spray foam, on the other hand, is still a bit of a concern just because it is being evaluated. The best thing to do is to investigate further and see if there is any type of chemical impact going on in the home.

There is one particularly worrisome ingredient, known as methylene diphenyl diisocyanate. There are a bunch of issues with this ingredient, as there have been studies that show that it can damage lungs, cause asthma problems, and more.

Not only have states declared it an issue, but the US EPA has concerns over spray foam safety as well.

Manufacturers are being a little vague on helping out people when it comes to staying safe while using this foam. It is something people need to consider if they are trying to stay as healthy as possible while still benefiting from the foam.

Installation Safety Regarding Fire, Moisture, and Mold?

There are a lot of concerns people have in regards to insulation each and every day. It is natural for people to be scared about what happens during a fire, but smaller issues like moisture buildup and mold can be frustrating as well.


Flammable Insulation

There is nothing to worry about with fiberglass and mineral wall insulation. It is naturally non-combustible which is great news for people who are trying to stay safe.

Spray foam insulation can fight off fires up to 700°F. At that point, there is a chance of the insulation igniting. Cellulose insulation has some level of fire resistance, but it requires fire retardants to keep the majority of people safe.

As is the case with all fires, there are a lot of different factors that can lead to things getting out of control. Most insulation is not going to cause any true additional issues, but if it gets bad enough, it is not going to matter.


Moisture In Insulation

It is very difficult to keep moisture from causing harm with any type of insulation. In fact, no insulation is going to stay completely dry, so it is all about managing the issue as much as possible.

This is one of the many reasons why people will only use professionals to install insulation. It is worth asking them about what type of approach they will take to managing moisture overall. Most people know what areas are the most vulnerable, and it is important to consider those things.

If there are already a lot of moisture issues at the home, try to fix as much as possible before putting new insulation in. This is going to make life a little easier overall, and everyone wants to feel like they are starting in a pretty good place before something new goes in.


Moldy Insulation

Mold and moisture go hand-in-hand, and that is just one of the ways that it can get pretty messy with insulation. If there is any food around or organic material in any way, spores can start to form, and it can get pretty serious.

The only insulation that is a possible food source is cellulose. It needs to be properly treated if there seems to be any chance of mold forming.

Spray foam, fiberglass, and mineral wool are not food sources, so they are a little less vulnerable. However, there is an opportunity for mold to grow on just about any surface with the right type of scenarios.

Be on the lookout for any insulation that promises that they are 100% resistant to mold. This is impossible, because mold can form in so many different ways.

The best way to cut down the opportunity of that happening is being proactive, but sometimes it just happens even if people are up on their cleaning and monitoring.

Why Insulation Matters For Soundproofing 

Insulation makes a huge difference in so many different ways for any home. Some people think that all insulation options are the same, but there are definitely variables to keep in mind.

Anything from cost to effectiveness can play a role, and people should be capable of doing their own research before jumping into anything in particular.

Take a look around and consider the pros and cons before jumping in. There is no reason to hurry a decision only to regret it later. Most end up with mineral wool or fiberglass roll, but the other options have benefits as well.

How To Soundproof A Wall – 9 Ways That Actually Work!

Walls can be too tricky for people to soundproof if they have never done it before. It might seem like it is relatively easy to put in the necessary work, but not every technique works as effectively as it should. The good news is that there are a few soundproofing methods out there that people can try to see what is most effective for sound proofing walls.

How to soundproof a wall? The most effective way to soundproof a wall is by adding a second layer of drywall. You should use a 5/8″ drywall as this is more effective for soundproofing a wall than the standard 1/2″ drywall.

Most of these other tips aim to be effective and cheap, as no one wants to have to spend a ton of money soundproofing a wall. It can be pretty useful to make some subtle changes, but there are times when people need to go ahead and spend the extra money for peace and quiet as well.

Here are the best ways to soundproof a wall as effectively as possible. These are in no way in order of effectiveness. One thing to note is if you’re using more than one soundproofing method this will increase the STC rating of the wall. 

1. Strategically Placed Furniture In The Right Areas

Soundproofing walls with furniture

This might be the cheapest and easiest way to notice some benefits of soundproofing a wall. A person does not have to spend any additional money, and it just requires a little bit of moving around to make it all work. It is also pretty useful, especially if a person has furniture that really comes in handy.

Perhaps the best piece of furniture to help soundproof a wall is a large bookshelf. This can act as another barrier for the wall, so it automatically becomes thicker. Some of these bookshelves can take up most if not all of a wall, and it does not even make the rest of the room look out of place.

The general rule of thumb with furniture is that a room needs to be filled to not risk an echo. If the room is entirely empty, it will be very easy for sound to bounce off the walls and become an issue. The same can be said for a lot of hard surfaces only. That is where actual furniture that we will sit on comes in handy.

The best thing to do is to have a few softer furniture pieces balanced out throughout the room. This helps to absorb sound so that it is not bouncing around nearly as much. This also works to a certain extent when right up against the walls, but at the same time, people do not want to put their seating areas right up next to a noisy wall.

If the other side of the wall belongs to a person, the same furniture concept is applicable. The goal here is to use furniture as a semi-permanent layer to make the wall as thick as possible. It makes a pretty big difference once everything goes into place, and a person might not even have to spend any additional money to get it to work.

2. Use Decorations Strategically

Most people are not going to leave their wall completely bare, as it just makes no sense to have a few things up to make everything look complete and moved in. While doing that, they can also act to soundproof the walls to make them a little quieter.

Wall art and decorations by themselves might not do a world of difference, but it does help with noise reduction and soundproofing in general. There are ways to enhance this to work as well.

The first thing to do is to look at wall decorations that have good bulk to them. If they are pretty heavy by themselves, they will create a barrier that helps block sound from coming and going.

Think of something like canvas art, decorative quilts, or even sticking on wallpaper. They all will help to a certain degree, and they can play off of each other in balancing out the room.

Sound can bounce off of walls pretty easy, so it is essential to have some ways to reduce that from occurring. By balancing out the walls with some art and decoration, the chances of noise going around are significantly reduced.

Another way to make wall art and decorations soundproof is to put some material behind them. This will be entirely out of sight so that people are not distracting people from what is placed on the wall, but it adds some bulk if it is not there already. This works very well behind the artwork, and using some pretty thin material will not make people question anything.

The wallpaper idea is the best for full coverage, but there is only going to be so much wiggle room as far as thickness is concerned. If the wallpaper is too thick, it is going to look unnatural and stick out. Some people will go as far as using thicker paint and a thicker wallpaper to make the walls thicker overall.

3. Acoustic Foam Panels

The first couple of ideas are pretty affordable for anyone who is on a strict budget. Maybe there is not much of a need for soundproofing either, which is another way to make life easier.

However, if they do not work out, there is a way to start installing soundproof foam panels to help balance out a room filled with noisy walls.

It might seem like soundproofing professionally is another way of saying that it will be an expensive endeavor. The good thing about foam panels is that they are pretty affordable to make, and there are enough competitors out there that a person can find exactly what they are looking for and still stay under budget.

In fact, soundproofing panels are now so much better in today’s world. A lot of companies offer very versatile options that come in different colors and even patterns.

People can start to incorporate these panels into their home design so that it does not stick out. They are doubling his wall art in some scenarios, even if it might not look quite as fancy.

The installation process of soundproofing foam panels is where things get a little tricky. As long as people are willing to put in some time in researching where everything goes, they could probably do it themselves.

Having professionals install these panels also helps tremendously. The key is putting them where the reflection points are throughout the room. This makes it possible for people not to fill the entire room with a bunch of foam panels, making it that much more efficient.

4. Fabric Panels

Foam panels are pretty popular these days, but fabric wall panels can work in many similar ways. They are a little more expensive than foam, but many people like the way they look and the way they perform. They do a pretty good job of absorbing sound, and they can be made it look pretty nice as well.

The key with fabric panels is to look at the NRC rating to see if they are living up to expectations. It is one thing if they look great, but not all fabric panels are created equally.

Some companies are even going as far as exploring customers because people automatically think that it is better. It is still very much part of the solution to research everything and find out just how great it is at soundproofing.

What type of fabric do people use with fabric panels? The two to look out for are jute and microsuede. Microsuede is indeed a little more expensive, but people like the fact that it gives off a slightly classier look. Either option tends to work pretty well, but microsuede fabric panels are definitely worth considering.

5. Sealing Cracks, Holes & Crevices

acoustic caulking

It is pretty surprising to some people just how quickly walls can form cracks and even holes. It does not take much for everything to happen, and when it does, it gets really frustrating.

The good news is that there are many ways to make fixes without ever having to hire a professional. With a few solutions meant to make things pretty easy, the drywall can easily be spruced up.

Out of all the different types of sealants out there for cracks, perhaps the best of the best in acoustic caulk. It is still a relatively new product compared to others, but as the name implies, it does a much better job with sound in general.

The way acoustic caulk works is that it is a rubber type of material that is pretty easy to apply for anyone who has given it a try. It does not change shape, as long as it is properly put onto a wall.

It is a permanent type of solution that will still stay flexible, which is precisely what a person wants with a wall. Most importantly, it will not shrink or even crack during the entire time.

People might initially realize that they need to use more acoustic caulk and other forms of cracks that start showing, but they will not have to be going over their previous work again and again.

Some companies call it acoustic caulk, while others will refer to it as noise proofing or sound sealant. Whatever the cases, the application process is certainly not tricky by any means. In fact, a lot of people will start the planning process and begin on the very same day.

These are the keys to ensuring that the first application of acoustic caulk will be the last. By following a simple guide, people will see better results that will encourage them to use this process for other troubles as well.


Acoustic caulk is not the most toxic material by any means, but people still need to be in a well-ventilated area with protection. The smell can make people a little dizzy at times, and there is also a chance of the caulk getting on hand.

Make sure to invest in some gloves and maybe even some eyewear for added protection. Of course, only apply the acoustic car while wearing clothing that might not make that much of a difference if it is ruined or not.

Clean Off The Wall

The wall needs to be as clean as possible when applying to keep the caulk. If it is dirty and a person tries to fill in cracks anyway, it will not be nearly as effective.

Take the time to clean the wall off in the very beginning. If done correctly, there will be no need of having to fix things later on.

Invest In A Caulking Machine

Caulking Tool

It is technically possible to apply acoustic caulk without using a caulking device (Amazon), but it just makes life so much easier to use one instead. By having a fine nozzle to get into any crevice, it makes life a whole lot easier.

Put in a good amount of caulk in the beginning and do not worry about putting too much. It is better to get everything appropriately filled instead of having to go back and doing it again.

Clean Off Excess Caulk

It is better to put too much into an area instead of too little because it is pretty easy to smooth things out. Just use a tool that usually comes with caulking set to ensure that the wall goes back to being as flat as possible.

Some people even use their fingers if it is still pretty fresh and easy to scrape off. Some people go the extra mile and sand things down, but it is not always necessary depending on where a person is situated.

6. Curtains and Blankets For Soundproofing

It should be clear by now that thick fabric can help with soundproofing just about any area. People have been using different fabrics as a way to soundproof where they live for quite a while now, and two pretty easy ways to go about it is to utilize soundproofing curtains or blankets.

They are both made of similar materials, and they are pretty easy to put just about anywhere. Curtains obviously make a lot more sense around windows, but either option can help complete a wall.

Soundproofing curtains (Amazon) are beneficial for people who are trying to not only control sound but the light that comes into their home as well.

There is nothing worse than having a lot of distracting sun coming into a home and really causing trouble. No one wants to have to deal with super sunny rooms that it becomes impossible to sit in during certain parts of the day. That is when the curtains can be pulled, and light can be all but eliminated.

The same goes for sound, only it can act as a sound barrier 24 hours a day. Windows can be a pretty vulnerable area for the home compared to the rest of the wall. Having curtains that are easy to pull adds an extra layer of protection that everyone can count on in the end.

The great thing about using blankets is that they will do an excellent job of being moved where every person needs them.

Some people will put moving blankets or soundproofing blankets up on a semi-permanent basis, while others will use them when necessary. For example, if there is sound coming from an area that is going to be only temporary, it can go over a particular part of the wall to add some layers.

It is a little tricky to hang moving blankets to a wall, but some come with grommets that make it a little easier. When that is the case, they go up the same way that curtains go up in many instances, and can be pretty valuable overall.

With a person ultimately decide to go with curtains or blankets, keep in mind that even adding both can provide some temporary value. Most people will not go with both since they look a little weird on a permanent basis, but it is always worth trying out if nothing else seems to be working.

7. Mats

Mass Loaded Vinyl From Amazon

People are pretty well aware of soundproofing mats from a floor standpoint, but there are actually options for the walls as well. They will be made up of some quality high-density materials that can help block the sound coming from all angles. It is usually pretty easy to install since they are so thin as well, making it not stand out as much as some people might think.

The good thing about adding these types of mats is that they can go over or under drywall. If a person is installing drywall, it obviously makes more sense to go underneath to hide it. If it is going over drywall, there might be a chance to put something else over the top so that they do not stand out as much.

The drawback is that most of the mats are only going to come in the color black. It is definitely not the best for a designer look and feels, but they are effective.

A lot of people use them because they are one of the most effective options out there without having to break the bank. Mass loaded vinyl, in particular, is what a lot of professionals will use if they will need to make sure that their walls are as soundproof as possible.

8. Treating The Most Vulnerable Areas

A lot of people would love to have a room with just standard walls from a soundproofing perspective. It would make no sense controlling sound, but that it is never the actual set up.

There are many obstacles that people need to overcome if they want to make sure that their room is as soundproof as possible. The walls might actually be the easiest part, but those weaker areas need treatment as well.



When does the first thing that most people will pay attention to, as even thicker window panes are thinner than a typical wall. Just about every room will have at least one window, and some will find it to be a real issue when it comes to controlling sound. Sounds can come from interior walls or exterior walls, frustrating people to no end.

The best ways to make a big difference with windows are looking into a higher quality piece of glass or installing curtains. Windows can be pretty expensive if they have a build specific for controlling sound. Some people are able to afford it, but others do not want to waste that extra bit of money.

The good news is that a person might only need to invest in a new window or two in specific areas.. The whole house might not need the same level of soundproofing so that a person can save a little bit of money there.


So many people think of curtains as the only way to control the light coming in and out of the room. If it is made of thick, dense material, it can also be beneficial for soundproofing.

They make so many different options as far as soundproof curtains are concerned that they can find what they need without breaking the bank.

Pay attention to thread count, how tightly woven the curtains are, and even the layers provided. It is best to make sure that the curtains are able to cover the window fully, as even a little bit of exposed area will let lights and sound in.

Insulation is just the same as any other set of curtains. Some people will do it themselves, but others will rely on past rods left from previous curtains. Ensure that everything is measured properly and that it matches the way the rest of the room looks, and people should be good to go.


In order to get into a room, every place needs at least one door. These doors are usually not the greatest for controlling sound, especially if they are an interior door.

A lot of designers will skimp on interior doors, making them mostly hollow and pretty lightweight overall. Couple that with the space in between the door frame and floor, and this can be a vulnerable area.

If a person wants to treat the door directly, there are a few different solutions. If a person has the money, they can replace the entire door and go with something built for control and sound a little more.

Look for something that is thick and not hollow, providing people with a lot of the same material that they can get from A wall. It will make a little bit of difference right away, but there is still something to be said for those areas where the sound has a chance to leak through.

In those areas, look to put a doorstop or sweep at the base of the door. This is going to close that gap while still allowing people to come in and out. These are usually pretty affordable to invest in, and they are inexpensive enough that people are not going to be in too tough of a situation.

Not everyone wants to install a brand new door, so there is either installing soundproofing material inside or outside the door, and giving it a bit of a redesign.

If this door is leading into a room that constantly has sound problems, it is usually worth putting in the extra effort to make it a permanent solution.

Moving blankets really come in handy when trying to soundproof a door as quickly as possible. There are a lot of people who will make sure that they have blankets readily available so that they can be put onto the door as quickly as possible.

It may not be a permanent solution, but it does do the trick if nothing else is working at the time. There are way too many people who do not give this option to try, simply because it might not look as nice as some of the other options. However, there is not always a need to have a permanent solution.

Air Vents

It is important to have air vents in a room to help with temperature control, circulate air, and so much more. The bad part is that they are not the best for controlling sound, and people are constantly trying to fight against them so that they do not become a distraction.

No one should be recommending that air vents are completely blocked off or even removed. Since that is not a solution, most people are looking for something that is a little bit temporary to be quieter when it needs to most.

The best way to do that is to count on moving blankets. They can be put up for a short amount of time, and then easily removed when the air vents need to actually work.

If the air vent itself is making a lot of noise throughout the day, it is worth repairing or totally replacing instead of just trying to live with it. There are way too many people who do not put in that extra bit of effort to fix everything, and it can be frustrating, to say the least.

If the room has too many air vents or does not really work at all, it is worth blocking it entirely. It will not compromise how the room operates at all, and it just becomes a place for sound to become a nuisance. There are way too many people who have air vents that are no longer working, and they do not seem to make any changes to get them out of the way.

9. Soundproofing Methods That Do Not Work as Advertised?

Since so many people are looking for ways to improve their homes from a soundproofing perspective, it is easy to fall int the trap of using some methods that do not exactly work that well. While they may help out some, most people need to do more than just the bare minimum to really see (and hear) results.

Some of these tips have already been discussed above, but they should only be looked at as an additional option instead of something to really provide soundproofing assistance.

For example, if a person does plan on painting or using wallpaper, it is worth the extra effort to invest in something to help with soundproofing. Just do not expect it to make much of a difference by itself.

Soundproofing Paint

If this sounds like it is too good to be true, that is because it actually is. Soundproofing paint is going to work in a lot of the same ways as regular paint, and that also means it is not going to do much for noise.

Putting on any layer of paint is only going to add a little bit of mass to the wall, and no paint is strong enough to make any type of significant difference.

Yes, thicker paint or multiple layers of paint will technically make some of a difference, but none of the people should be thinking of this as a true solution.

Only invest in this type of paint if the goal was to put new paint on the wall in the first place. Otherwise, it is a waste of time to paint everything the same color.

Acoustic Wallpaper

Wallpaper is meant to be thin so it can go against everything to get a really heavy and thick option on the wall. Not only will it look weird, but there is a chance that it will not be able to hold up for long periods of time. The reason why wallpaper is lightweight is so that the walls can keep things up for a long time.

Between paint and wallpaper, wallpaper might make slightly more of a difference. However, people should ultimately go with whatever option they want from a design standpoint.

It is not going to make any type of difference that a person should change exactly how their home looks for very minimal changes.

Rubber Foam

Not all foams are created equally, and a common misconception is that rubber foam is going to actually help with soundproofing.

Think about the type of foam used for an exercise mat, a mouse pad, or other uses around the home. It does not have the type of materials needed to help with noise reduction, and that makes it worthless to install.

There are foams that do work but make sure that they have an NRC rating and are meant for soundproofing walls. It needs to be able to absorb sound and also add some mass to the flat surfaces. Just collecting a bunch of foam rubber around the home and hoping for the best is not going to work.

Soundproofing Everything But The Walls

Soundproofing everything but wall

Adding carpet, rugs, and many other options out there can help to a certain degree, but their walls will still be a huge noisemaker. They are one of the most essential surfaces to treat in every single home, so blowing that part off does not make any sense.

Yes, it is easier to throw a few things down the ground and not have to worry too much about anything else. Soundproofing the floor is important to a certain extent, especially if there is sound coming from below.

However, walls produce sound from all angles, and no one wants to have to deal with the huge hassle that is going on at all times. Having bare walls does not make sense in the first place, so putting something up will make at least somewhat of a difference.

Think of every single thing added to other flat surfaces as a bit of a bonus. At the end of the day, it all comes down to making sure the walls are covered, and that sound is not becoming a huge issue.

There are way too many people out there who think that they just have to live with what type of walls they are dealt with. Trust in the products that do work, and do not fall in love with fixes that seem too good to be true.

Why You Should Look Into Soundproofing Walls

Most people would love to have a quieter home or business when inside. It is easy to limit distractions, it allows people to hear the sound they want to, making the area that much more welcoming.

There used to be a time when people did not really have much to fix a noisy area, but now the materials are out there to make changes without spending a lot of money.

Whether a person ultimately wants to do all of the fixtures themselves or hire a professional team to take care of things, it is worth soundproofing walls in every place else inside.

No one should be putting up with poor acoustics, especially if a room is designed for entertainment, recording, or other sound-related activities. It might be worth giving smaller solutions a try before investing in more serious solutions if it does not seem to work.

Active Noise Canceling In Cars – Vehicle ANC Work?

Active noise canceling is mostly associated with headphones these days. However, there are more and more people who are looking to reduce sound when they are driving down the road in their car.

Active Noise Canceling in Vehicles? Instead of wearing headphones, which can be dangerous when driving, some companies have active noise-canceling (ANC) technology already installed in the car. ANC technology takes full advantage of your car’s speakers to send a frequency in the cabin that cancels out the constant white noise your engine and road noise creates. 

How Active Noise Canceling (ANC) Work in Cars?

As one might expect, the noise-canceling ability of a car works very similar to headphones, only on a bigger scale. Some microphones are installed inside the cabin of the vehicle that will pick up any sounds and send them to the computer.

This creates sound waves, which can be used to cancel out unwanted noise. When the system figures out what noises are unwanted, they can cancel things out by using an opposite wave.

The beauty of active noise canceling is that a person does not necessarily have the sound system on to use this new type of technology. It will still put out a sound to stay as quiet as possible for those in the cabin.

When there is a wave that cancels out the other, it creates a very flat noise that really does not sound like anything at all to most people. Some active noise canceling setups are better than others, but they all make a pretty big impact on the type of sounds people hear.

Is Noise Canceling In Cars Safe?

The short answer is yes, Active noise canceling in cars is safe, otherwise, it simply wouldn’t be installed in a vehicle. 

Active noise canceling technology in cars is only able to cancel out constant white noise like road noise and engine noise. Horns and emergency vehicle sirens are unable to be canceled out because that type of sound is ever-changing, it is not a constant white noise and will NOT be canceled out. 

ANC technology can actually make your commute safer because you will be able to hear sporadic noises like a police car or ambulances sirens clearer now that you got rid of your own white noise. (Source)

What Also Helps With Active Noise Canceling In Vehicles?


Many new cars that already include active noise canceling will also use acoustic glass for the windshield and side windows.

This is to ensure that everything is maximized inside the car, and people get the best sound possible. This is also available as something to do aftermarket, but keep in mind that it gets to be pretty expensive. 

Another available option is that there can be a seam sealant (Amazon) applied that goes between the body panels of the car. This helps to reduce vibration, sound, and even act as a way to waterproof everything. Once again, this is something that people can do after the fact, and it shows some pretty positive results overall.

The technology used to be limited in that it could only work for a tiny device like headphones. Now, filling the entire cabin with active noise canceling can genuinely be the game-changer plenty of people are looking for.

Will Active Noise Canceling Cancel out the Car Sounds You Like?

Engine noise canceled?

A quiet interior sounds like a great idea for many, but what about those who want to hear the engine roar? Will all the other noises be locked out?

Some automakers are going the route where they are playing music that matches up with certain sounds through the speakers.

For example, recording the sound of an engine and playing it simultaneously as the engine is doing work is one way around this.

Drivers can hear the sound and still feel the satisfaction, and everyone else and outside of the car can listen to it normally.

When a person does not want to hear this, there is an option to turn this feature off. It seems like a good option to have at this point, but it remains to be seen just how much of a demand there will be outside of the sports car world.

Why Is Active Noise Canceling Important In Vehicles?

Driving In Peace With Active Noise Canceling

It might not seem like a big deal when driving, but it is a bit of a luxury feature for many people who simply want to hear what they want to hear.

Instead of having a lot of different distractions while driving down the road, active noise canceling can allow a person to focus and feel like they are in the best setting possible.


Audiophiles are always going to love having the ability to hear music as crystal clear as possible. Sound systems have gone through some overhauls over the years, and people are always looking for the type of music they can really enjoy.

While driving down the road, the experience is truly a great one with solid music choices to rely on. It is more about hearing things clearly with active noise canceling rather than going as loud as possible.

So many people went with very loud sound systems in the past because it was the one way to be able to hear everything. It became a little obnoxious, and some people even received tickets for listening to music too loudly, but now that is not as necessary with active noise canceling.


Whether it is a business or personal call, many people have important conversations while driving down the road. It just makes sense to hear not only the person on the other side but to have spoken word go through as clearly as possible.

It can sometimes get to the point where people can’t talk on the phone in the car if it is too noisy. Active noise canceling can help remedy the situation, allowing for a little more productivity while driving.

The Sound of Silence

Some people use driving down the road to relax and really take everything after a hard day of work. Having many distractions can easily get in the way of a very important time for some people.

This might be their one time to relax and have an easy time driving home, but it gets out of hand in a hurry if different sounds are coming from all around the drive.

Yes, some people will use active noise canceling without any other sounds going on. They want to have things as quiet as possible, and this is the best way to achieve that.

Conversations With Others In The Car

Finally, road noise can get to the point where people have difficulty talking to one another while in the car. An excellent way to fix the situation is to invest in active noise canceling.

It will make for a quieter cabin overall, which means people do not have to scream to each other to have a conversation.

It has always been a problem in certain scenarios where people can’t hear each other, especially if one person is sitting in the back.

Being able to use normal voices instead of having to scream to each other can make things a lot less stressful while driving.

Other Ways Of Canceling Noise In Your Car 

Noise canceling, to some degree, has been around for quite a while. It is just that some of the methods are a little bit more cumbersome than others.

It comes down to how much money a person has, as some of the old methods still do work, but active noise canceling is the best way to go.

While some companies still use a few methods out there, the world has largely changed as time goes on. It still helps to have some of these methods in place, but active noise canceling puts less stress on these features.


Many people know all about adding thick insulation (Amazon) to any car to help with noise to some degree. This insulation can look a little different when installed, it adds quite a bit of bulk to a car as well.

While it works to a certain degree, it is not a type of active noise canceling that some people are looking for in today’s world.

The good news is that for people who want an inexpensive way to help with noise cancellation, this might be the way to go. There are a lot of reasons to look in this direction, as it saves money and is relatively easy to install.


Kilmat Sound Deadening Mat

One of the easiest ways to get rid of the noise in the car is to throw some mats down on the ground. A lot of the noise comes from below, and mats do not even need to have a way to securely stay in place.

Many people will still use soundproofing mats (Amazon) to keep it a little more temperature-controlled and sound from getting out of hand, but active noise canceling is making them irrelevant.

Going The Electronic Method

Active noise canceling is made possible by going with electronic methods of controlling everything. Instead of just muffling the noise the best way possible, it actually cancels out outside noise so that a person gets a clearer sound overall.

Is Active Noise Canceling Inside Cars The Future?

There has been a lot of positive feedback from active noise canceling inside cars so far. People love the fact that they could have a much quieter ride, while still being able to pick up some of the more essential sounds around them.

No one wants to have everything completely shut off when driving because that can feel a bit unsafe. What active noise canceling does is filter out some of the non-important sounds and allows people to hear everything essential.

As technology becomes cheaper, it seems like this will be a feature that shows up with many different cars out there. Some people will not wait and instead install it on an older model, which is fine.

People have long complained about all of the different road noise issues they have. This might be the most effective way to handle things.

Acoustic Panels – What & Where – 15 Facts

To make any defined space sound a little bit better, there is always the option of acoustic panels. There are many people who have relied on acoustic panels over the years as one of the easier and most cost-effective methods to have better overall sound. It certainly is a lot easier than completely changing the makeup of a room structurally.

How exactly do acoustic panels help, and where should they be placed in a room? That is a little trickier for people who are trying to do things on their own.

Fortunately, following some recommendations and seeing what works in a particular room can lead people to the right solution. It might take a little bit of trial and error, but most people will find a way to improve sound quality in a way that satisfies them.

What Are Acoustic Panels?

Trademark Soundproofing Acoustic Panels

To put it as simply as possible, acoustic panels are sound absorbing options that help control background noise and limit reverberation and echo in a particular room.

They can be placed vertically or horizontally, and they have different principles that all contribute to quality acoustics. If the panels can work together to help with absorption, diffusion, and attenuation, they are doing their job.

Just like there are vertical and horizontal acoustic panels (Amazon), most of them will either act as an absorber or diffuser. Both are necessary to balance out a room and to make things sound as great as possible.

What is the difference between the two? It is important to know that these are not the same at all, and most rooms need a balance of the two to sound as great as they should.

With sound absorbed in, this is where the goal is to remove any sound energy from an environment to help control things like bass. It might leave a bit of a dead and dry sound if only absorption is put inside a room, but it works well when coupled with diffusers.

Absorption is generally considered the move to go with smaller rooms, but many people do not like the fact that rooms of all sizes are pretty lively in general.

A lot of rooms can benefit from having a bit more of a muted sound, which is going to make it more enjoyable for people watching entertainment or focusing on work.


Diffusers act as a way to spread outside energy so that everything sounds better in a specific space. By scattering the energy around the room, a diffuser can allow the sound to travel evenly in certain directions. When set up properly, sound diffusion will redirect the sounds that people want to hear to the listening areas.

Diffusion makes sense instead of absorption when a person is looking to control echo and not make the room sound completely dead.

There is always a bit of a balance between diffusion absorption, especially as technology gets better and better with acoustic panels.

The Importance of Reflection Points

Covering the reflection points

The best option to put at the first reflection point is a diffuser that is medium curved. This is because it will make the stereo stage a little wider, as well as more focused. As long as it is curved, it will provide enough value overall that it is worth putting in the extra time.

Without treating the reflection points in a room, a lot of the work put into using absorption panels ends up being all for nothing. Just randomly putting up panels where a person might think they go is not going to make that much of a difference at all.

Be smarter with the panels, instead of trying to fill the wall with as much as possible. It is more affordable, looks better, and makes more of an impact on noise.

Is it fine to put an absorber at the first reflection point? A lot of people have traditionally followed this route, and it has worked to a fair amount of success.

It is certainly better than doing nothing at all, and it is not necessarily considered wrong. The better method will be a curved diffusor though because a person should be looking to redirect and maximize the sound at that crucial reflection point.

How To Find a Reflection Point In a Room?

The easiest way to find a reflection point is to have someone else sit in a traditional seating area while the other is using a mirror to measure everything off. While one person sits in the chair in the middle of the seating area, the other person moves the mirror along the wall until the sound source comes into view.

There are other ways to take measurements as well (like taking measurements), but this makes the most sense to make it as practical as possible.

People are generally going to be sitting in a specific area in a room, and they need to understand where the sound source is coming from and how it reflects off the wall.

Treating the Corners In a Room

Instead of using the absorbers in the first reflection point areas, they make more sense to be placed in each corner of a room. Using fabric absorbers makes a lot of sense to help with side to side and back to back reflections. The corners can really become an issue in some rooms, so having that extra bit of treatment helps significantly.

Remember to balance everything out in any room when adding panels. It makes no sense to treat three of the corners and leave one empty. Make sure to budget properly so that all flat surfaces are covered.

If the corners are still causing a bit of a problem, both sides can be covered with acoustic panels. This will bring the total to eight in the corners, which might seem excessive to some.

However, they do make a pretty big difference, and it will ensure that the room stays sounding the way people want it to.

Acoustic Panels For Ceiling

Sound Cloud Ceiling Panels

If treatment on the walls is good enough, a person does not have to go with acoustic panels on the ceiling (Full Article). However, there are many people who will go this extra mile to make the room sound that much better.

Acoustic panels on the ceiling (Amazon) need to go on the first reflection points as well. A lot of the same techniques used to measure first reflection points can be used in this regard, so keep that in mind.

The reflection points will be around the halfway point between the sound source and the seating area, unless the sound source is at a much different level than a person’s head.

The other area that needs to be treated is over wherever a person plans on sitting in that room. This is to help with exactly what a person hears in the area as far as sound reflections are concerned.

It gets a little tricky to add acoustic panels to the ceiling, but there are a few ways to do it. Some will use the same type of panels that they have for the walls, while others will switch out the ceiling tiles a bit to have something more secure.

If a person can use tiles that are easy to switch out, this is the easiest option. There are acoustic panels that actually fit into these tiles to replace a traditional ceiling.

What About The Floors?

It is important to treat some floors from a soundproofing perspective, but they do not exactly take acoustic panels very well. Instead, it makes more sense to look for alternative options that can help.

The easiest way is to have some rug or carpet on the floor to eliminate that flat surface. Remember, the floor needs to be balanced out with the ceiling, or else there is a chance of some serious sound bouncing around.

It does not have to be anything too special with the floors, but it is pointless to do all this work with acoustic panels and leave the floor flat and hard for sound to bounce around.

When And Where To Use Acoustic Panels?

Panels are used more than ever these days, as people are finding new ways to benefit from them. Whether it is the home or office, some people just love that they can make a room that much better from a sound quality standpoint with only a few panels put on the wall strategically.

Limiting Sound Transfers

People use vertical acoustic panels so that they can limit sound transfers in a particular space. When they are placed vertically, they can prevent the sound from traveling from one part of the room to another.

Not only that, but vertical panels come in handy when trying to lower any background noise that is a little troublesome. Background noise is something that many people have dealt with over time, but it no longer has to be nearly as distracting as before.

The more a person wants to remove any background noise, the bigger the panels need to be. If a person wants to completely remove all background noise, covering from floor to ceiling is the best way to do it. However, most people will not do that, instead, go with something a little more practical.

Helping Out Direct Sound Absorption

The vertical panels provide some value, but horizontal panels are used to help with absorbing sound directly.

This means stopping any sound waves from spreading where they should not go, and that means converting sound energy into heat by using friction.

Horizontal panels are always going to work well with absorption, and they can balance out a room very well.

Small Rooms

In a small room, sound waves generally bounce off of walls before anything else. That is because walls will be close to the sound source, and it can easily start to bounce around quickly before it becomes overwhelming.

To handle this effect, looking at wall-mounted acoustic panels is the move. They will help with the absorption of sound, killing the amount of waves that are constantly bouncing off and going back into the room.

Smaller rooms do not necessarily need a ton of panels, but they should be in locations closest to where sound sources are coming from.

In most cases, sound is only coming from a few limited areas in a small room, so finding those areas and treating them helps significantly.

Large Rooms

Sound waves become a lot more unpredictable when in a bigger room. Sound will not bounce back in a large room as much, as there are times when the original sound does not even reach that reflection points to cause a problem.

The difference is that the ceiling is a lot more important in larger rooms. They need to be treated with ceiling-suspended acoustic panels to help out the space.

This helps absorb sound waves so that they do not cause problems. Putting them at different heights will help create air pockets that trap sound waves from causing problems as well.

It still makes sense to have acoustic panels on the walls as well, but they do not necessarily need a ton of coverage to help out. Once again, it is a matter of putting them where sound sources are usually, and then going from there.

Do You Need A Lot Of acoustic panels On The Wall?

Acoustic Panels Wall Instal

It might seem like after all is said and done, walls are filled with acoustic panels to have any type of change.

While it does require a certain amount of acoustic panels that make a difference, it is not going to be that big of a hassle to add panels here and there and ultimately decide what makes the biggest difference.

How Expensive Are Acoustic Panels?

Like anything, because the panels come in many different sizes, quality, and prices. It is not particularly pricey to use acoustic panels, especially if a person is putting them in the right areas to maximize efficiency.

By reducing the number of panels needed, a person can save a pretty significant amount of money.

A person should keep in mind that acoustic panels are a little more expensive than some other soundproofing material, strictly because it is more of an exceptional product.

It uses some advanced technology, and the market is not as competitive as it might be in a few years. Making such a change in a room is also a big reason people have found them to be a little expensive.

Companies know that they make a big impact, and people are willing to spend money on a difference-maker.

One great way to reduce the price of installing acoustic panels is to do everything without a professional’s need.

As long as the person can follow simple instructions on finding reflection points and install panels much like they would picture frames, it should work out just fine. They are lightweight and easy to move so that adjustments are possible as well.

Ultimately, people should not be too scared off by the price of acoustic panels. They are coming down in price every single year, and they are becoming more efficient as well.

Even a few years ago, people need twice as many acoustic panels to do a subpar job compared to today’s world. Now is the perfect time to get in and start using them in any type of setting.

Final verdict: Are Acoustic Panels Worth It?

With acoustic panels becoming more affordable than ever, it just makes sense to give them a try and see what works. They are pretty affordable, they come in many different shapes and sizes, and they can fit into the aesthetic of a room flawlessly.

There are very few negatives to give them a try, which is why so many people are willing to put in the extra work.

It might seem a little complicated at first, but a lot of it is trial and error. The fact of the matter is, no two rooms are exactly alike, so what works for one room might not work for another.

A lot of it also comes down to just how much treatment the room has naturally, as some rooms handle sound much better than others.

All in all, acoustic panels are no longer limited to musicians or professionals looking for the quietest areas possible. People are incorporating these in their homes more and more, making sense for people who like their peace and quiet.

How To Soundproof A Vehicle – Step by Step DIY Guide

People spend a lot of time in their cars. Some people want to make it as quiet as possible. Maybe they would like to enjoy the silence, have clear conversations while driving, or listening to their favorite music. Unfortunately, there is a ton of sound that can quickly get in the way.

Cars are becoming more and more soundproof before even releasing to the public, but there are always ways to make improvements to take it to the next level. For those people who are trying to upgrade their car to the best version possible as far as soundproofing is concerned, several techniques provide just that.

My Sound Deadening Material Recommendations from Amazon.



Soundproofing is one thing, but people should understand that it is impossible to get rid of all exterior noise when driving. There are just too many sounds coming from different directions, and it will be a hassle even to try to pull something like that off.

A person is better at targeting areas that are particularly problematic and trying to get the noise down as much as possible. The older the car is, the harder it will be to soundproof as much as possible, but there are ways to make improvements that are going to be tolerable for the vast majority of people.

Another reason to be optimistic about soundproofing a vehicle is that most of the techniques can be used without needing a professional to install. In fact, a lot of people rely on doing things himself, as a lot of processes are pretty straightforward. Even if a professional is needed, it usually does not take much effort to install some of the soundproofing methods.

Some of the techniques are going to seem pretty obvious, but some factors go into sound on the road that people will not realize at first.

Maybe they have been going about things the wrong way, and they are unaware of what type of impact sound can make. Here is a closer look at how to target specific areas in the car so that sound is reduced as much as possible.


soundproofing vehicle floor

The floor is perhaps the most vulnerable area in any car. There is a lot of car noise that comes from the undercarriage and many are surprised just how little insulation a car comes within standard form on the floor. Couple that with being so close to the ground, and this means a lot of road noise that can be pretty annoying.

The best method to soundproof a floor in a car is to invest in Floor Damping Mats (Amazon). There are a lot of different versions available, and they all strive to do pretty much the same thing. They will help with sound absorption, and also help to maintain the temperature in a vehicle.

Two brand names that are very well trusted in the industry right now are the Damplifier pro and Killmat. They are both constructed pretty much the same way, using butyl rubber as well as foil and a side of adhesive to hold everything in place.

If installed correctly and right up against the existing floor so everything can go cleanly over the top, the mats work extremely well.

The installation process for any individual is relatively straightforward. Some materials will need to be cut to size to get the perfect fit, but others will come pre-cut and ready to install in a standard vehicle. This can help reduce the amount of time it takes, and a person can get a full vehicle covered as well.

The most effective ones are going to be expensive, but it is better to have a solid single layer than something that is subpar and might need additional touchups later on.

It is very frustrating to go with the cheapest option, only to find that another layer is needed. Not only does this add bulk to the car, but it might end up costing more money overall in the first place.

All in all, a fair amount of floor damping mats will provide quite a bit of help overall for people who are noticing sound when they are riding in the car.

Sounds come from plenty of other areas as well, and that will be discussed later on in this article. However, this is probably the best starting point to see just how much of a difference these mats can make.

For a car that is at least five years old or more, it is especially important to add this little bit of detail. Once installed, they are pretty much out of mind and will hold up for years and years. Source


soundproofing car door

Not only are doors vulnerable, but they are also susceptible to having small leaks or even wearing away as far as traditional noise control is concerned. That is why insulating in the doors might be the next step, and one that is a lot easier now than it was just a few years ago.

Most doors these days have some level of insulation already installed, but older models might not have any at all. Once a person opens up their door a bit, they could very well notice that there are just a bunch of components with an empty inside to work with. Sound can easily travel to this, but that empty space can easily be filled with insulation that will help reduce noise.

Just like with the floor, the best way to add insulation is to peel things off and attach insulation in the proper way. It is not that hard for people to pull off, as there are walkthroughs available online as well for people who might be a little hesitant at first.

Quiet Tires

It might not seem like tires make a ton of noise, but once they are isolated, it becomes easier to notice just how much of an impact they make overall.

They are the only contact between the car and the road, so tires are going to make a lot of noise and vibration depending on what is underneath. To control all of the sound, getting proper tires will go quite a ways.

Most people are going to be more than satisfied with the tires that are currently on their car. This is the case if it is a brand new car, because most of the cars come with tires that are specifically designed for that type of car.

However, once the tires start to wear down a bit, it might be time to upgrade to tires that will help with noise control overall.

How can a person change how much sound comes from tires? Getting brand new tires certainly helps, but buying the right tires for the job is another part of the puzzle. These are a few tips that will help with figuring out which tires will work best.

Tire Size

A lot of people who have sportier-looking cars love the look of low profile tires. They might have a look that people are going for, but they are not going to do a person any favors when it comes to controlling sound.

This is because there is only going to be a little bit of rubber between the metal part of the wheel and the vehicle. With not much rubber to work with, the sound will travel fairly easily.

If a person only cares about sound, they should try to go with a tire that has a good amount of rubber as a buffer. It will absorb sound and also give some cushion to the vehicle, which reduces vibration. It may not look as cool, but people are willing to make the sacrifice.

Tire Width

The width of a tire with a car also makes an impact on how much sound a person will notice. If a tire is making a good amount of contact with the road, more vibrations pick up from the road in general.

That is why people should look for a narrow wheel if their car can support it. Some cars will not be able to support wheels that are a little too narrow, but this is something to play around with a bit.

Noise rating

Just about every manufacturer includes tire noise rating as a selling point these days. Companies love the fact that they can advertise themselves as a pretty quiet option overall, and that means people will gravitate towards these when they are trying to keep the sound down.

With the tire noise rating, there is a decibel rating that will be included so that people have a decent idea on what to expect. If a decibel rating is low, that means it is going to provide a little less sound overall.

Other than looking at decibel ratings, there is a three-wave symbol rating system as well. If a person wants the least amount of noise, they should be looking for a single line.

Tires that have three waves will usually be poor performing tires overall, and a pretty high level of noise. The reason why they still exist is that they are inexpensive, but that is not going to give a person any favors from a soundproofing perspective.


Sound does not leak through into a car too much from the roof, but in certain instances, people want to have a well-surrounded car overall.

That means that every surface that can let outside sound come in, so it needs to have some level of insulation. The roof might not need as much treatment as in the other surfaces, but it still will make a difference.

Sound deadening material that works on the floor and the doors will work best on the roof. Remember that people will be best off by looking for insulation that will help from a sound perspective, as well as controlling temperature. Heat rises, and it can start to leak through a roof that is not up to par.

Getting a nice, tight fit on the roof is also essential so that there are no problems later on. One of the biggest mistakes that some individuals can make when there are changes to the roof is that they do not use a strong enough adhesive so that people will benefit from the setup. Instead, they will need to make small repairs every once in a while, which can be extremely frustrating for individuals.

For an added amount of staying power, make sure that everything is clean and wiped off so that there is a clean slate for the soundproofing material to take the proper amount of insulation. This will ensure that it goes on smoothly, and then everything that goes over the insulation will be fine as well.

Insulation with the roof helps just as much with preventing outside noise from coming in as it does inside noise leaving. People on the road who might not necessarily want to hear loud music being played in a car will very much appreciate this type of insulation install as well. It might just be the difference between avoiding a scolding from law-enforcement for being too loud.


The trunk is arguably the most overlooked area of a car when it comes to soundproofing. Some people just do not realize the importance of having a trunk that is probably soundproof, even if they do not have anything back there in the first place. Sounds can still leak through the undercarriage in the trunk area, and cause problems for people in the driver seat.

High-quality soundproofing and deadening material is the best option for the trunk, just like just about any other surface in the car.

It goes on pretty much the same way as putting on material for the floor, as gravity will make this a little easier to apply. The looks of the soundproofing material might not matter as much, simply because people will not be staring at everything.


Wipers might not be the first thing you think about when wanting to soundproof a vehicle but if you’re driving around with loud, annoying wipers, you know all too well what I am talking about.

You can opt to replace your current wipers with a new set of silent wipers. You can also follow these tips from this article on how to soundproof your vehicle wipers.

Other Vulnerable Areas In The Car That Will Benefit From Soundproofing?

The short answer is that just about every surface inside the car can be soundproof to some degree. Some surfaces can benefit a little more than others, and it might not take that much effort overall to make a bit of a boost.


This might seem like a pretty innocent area of the car, but they have a design that is very similar to what a megaphone would look like. If there is no cup inside the cupholder, there is quite a bit of sound that can amplify throughout the car.

All it takes is some type of light insulation on the inside or outside of a cup holder. It will make more of an impact than many people realize, so it is worth putting in that extra bit of effort.

Wheel Well Insulation

Treating the tires definitely helps, but what about the wheel wells? For added sound control, using some layer of insulation will help cut down on any echoes that might form in this part of the car. This goes for the front and back tires, which are both vulnerable in certain scenarios.

Something like a sound deadener spray will work well, as a person does not have to take apart the car too much. It is a do-it-yourself option that many people will gravitate towards, but there are always professionals who will help to some degree as well.

How Easy is the Installation Process for Insulation or Sound Deadening Mats?

It always seems a little bit scary to tear apart a car and put something in as a do-it-yourself project. A lot of people are intimidated by going the extra mile and doing this type of work, but it really is a lot simpler than some people realize.

The fact the matter is, cars these days are designed so that they can be pretty easily taken apart to do different types of alterations. As long as a person has a few basic tools and a little bit of persistence, they can peel back the outer layer and put the insulation in themselves.

It is important to be a bit careful with the process, as a person does not want to rip or damage any part of their car, but it is pretty straightforward once a person gets the hang of it.

The key also comes down to making sure that the right amount of sound deadening material is purchased. Some people try to skimp just a little too much, and it comes back to bite them.

If there are too many gaps in between the mats, it is going to open up some opportunities for sound to travel through anyway. It is something that the vast majority of car owners simply do not want to have happen under any circumstances.

My Top 5 Vehicle Sound Deadening Mats.

Final Thoughts On Soundproofing a Vehicle

There is nothing worse than being overwhelmed by sound when riding around in a vehicle. It can be extremely frustrating no matter what a person is trying to do.

Cars are doing a pretty good job of letting people off the hook when making changes for themselves, but there will still be plenty of people looking to add some insulation and help with some sound deadening mats as well.

It is beneficial to still be able to hear some noise from the outside, as this will alert people if something is going on that requires attention. For example, if a person is never able to hear police or ambulance sirens, it can put everyone at risk a bit.

Sound deadening material is definitely coming down in price, and it is getting easier and easier to install without needing a professional. As long as people can follow some basic directions, they can get in a place that is much more comfortable overall.


Soundproofing – What Works & What Doesn’t

The process of soundproofing any area can be very rewarding when done correctly. However, it is a frustrating process for some, especially if they get the wrong information to go with in the beginning.

How can a person fight against false soundproofing information? Some trusted methods work, while others are more of a myth than anything.

At the beginning of this article, we take a look at what works best for soundproofing every single time. Later on, there are a few highlighted options that do not quite come through in the clutch as some people would like.

By cutting down on some of the options that do not actually work, people can save time and money. This makes for a much more pleasant experience with soundproofing in general.

Sound Absorbing Materials

Many people believe that reflecting noise is one of the best ways to control sound waves. However, in some cases, it makes sense to have them absorbed to kill any echo or reverberation.

Sound absorbing materials (My Recommended From Amazon) come in many different options, and it comes down to what type of room and how a person wants things to look.

All the sound-absorbing materials below work well, but some are more effective than others. From professional-level options to options that blend in with a normal look, try out a few different solutions before settling.

Acoustic Panels

A lot of people look at acoustic panels as the premium option for overall sound absorption. This is because they can have an NRC up to 1.0, and they are a little more aesthetically pleasing as well.

Some people do not like the way foam looks, and acoustic panels are made of wood and fit in more naturally. A lot of people compare them to wall decorations or even a picture frame, but they are made of the right material that absorbs sound instead of reflecting it.

Most people do not put up panels all around the walls, but they can if they want. They get a little expensive since they are sold as single options, but panels usually come in sizes that are roughly 2 ‘x 4 ‘. Cutting them up to fit exact locations helps.

Sound Absorbing Foam

Acoustic Foam

A slightly less effective form that some people use as an alternative is sound-absorbing foam (Amazon). These are also used for noise reflection can be a problem, or even a ceiling tiles if a person wants to go the formal way.

Sign absorbing foam has plenty of uses, and although the NRC is not as effective, they work in a lot of similar ways. They are easy to put up and are shaped similarly, with material composition being the only real change. A lot of times, people will switch up the names of these two options.

Moving Blankets

Moving Blankets

One of the most flexible options for sound absorption is the use of moving blankets (Amazon). They can be put just about anywhere, and they are one of the most inexpensive options as well.

They provide a decent amount of sound absorption that most people are satisfied with, but versatility is the major key in this regard.

Although they are called moving blankets and technically used to help move furniture, the reason why they help with sound adoption is that they are so heavy and thick. It makes it very hard for sound to penetrate, and they help the block out light as well.

A lot of people use moving blankets as a temporary solution if they need some soundproofing in a particular area. For a more permanent solution, there are several options out there, but moving blankets are great and that they go just about anywhere. Having them in the kid’s room is just way example of setting up some quick sounds option right away.

Acoustic  Curtains

Curtains are essential for practically any room, and there is no real reason to not invest in some heavy-duty options to count on. The reason why acoustic curtains (Amazon) work so well is that they add a layer to windows that can be particularly vulnerable.

Acoustic curtains might not always be marketed as such. For example, a lot of companies will sell the fact that they are also blackout curtains.

There are a lot of people who initially think of windows as a way to keep sunlight out and control, but they can be just as valuable for sound.

The best part about acoustic curtains is that they blend in with how a hole was supposed to look. There are a lot of soundproofing material options out there that do not exactly prove to be that aesthetically pleasing.

This is the way to get soundproofing without making much of a change at all. Install acoustic curtains in every room to help out with sound, especially if there is a lot of issues outdoors.

Door Sweep / Weaterstrip


Besides windows, a door in every room is the most vulnerable area for sound coming in and leaving. To close things up, weatherstrip and a door sweep at the bottom make the most sense.

The bottom of the door is always open for sound to leak through. Putting a door sweep (Amazon) on the bottom of the door will help as a permanent solution. For something a bit more short term, throwing some dense material towards the bottom of the door helps as well.

If the door is still leaking a lot of sound, using weatherstripping (Amazon) to fill the door frame up helps as well. All of the soundproofing material is pretty affordable, and can be installed DIY.

Soundproofing Insulation

If it seems like insulation is the best way to go, soundproofing options are more affordable than ever. It might not be the easiest to install at all times, but it is something that a lot of people have found to be effective.


A lot of people have used fiberglass insulation for quite some time. Soundproofing fiberglass is very effective, and it helps particularly with high-frequency noises. These noises can come from home theaters, rooms needed for recording, and so much more.

It is a lot easier to install soundproof fiberglass than a person believes. For example, building wood frames and spreading them out across the room make a lot of sense.

Whenever a person is handling fiberglass, they need to make sure that they are taking the proper precautions, because it is a bit of an irritant. Still, it is hard to match from an insulation perspective, and the NRC is excellent when installed correctly.

Mineral Wool

People love mineral wool because it is very rigid and able to fight off flames from potential fires in a lot of situations. People look at it as one of the best for thermal insulation, but it might be the absolute best from an acoustic standpoint.

The natural material is very easy to handle, and it cuts down on any influence of moisture. A lot of people use it in rooms all around their home or building, but it can be used as something useful and just about any scenario.

Sound Dampening

There are times when people just need something that helps with sound dampening. Materials can cut down on the overall energy of the noise, making it much less noticeable than before.

While sound dampening materials might not be quite as useful as other soundproofing solutions, it is worth checking out in many cases.

Mass Loaded Vinyl (MLV)

Known as one of the most versatile options out there, a lot of people use mass loaded vinyl (More Information) just about anywhere. In a car, it can help cut down road noise and kill any vibrations.

Inside a home, it can be tucked behind something to provide quite a bit of sound control without changing up how things look. Since there is a lot of mass in a very thin piece of material, a lot of people have no problem putting this anywhere.

It is worth investing in mass loaded vinyl (Amazon) to have around for just about anything. It is very flexible and was able to help out with, and it can go on virtually any surface.

Floor Underlayment

One of the easiest ways to treat any floor is to put some type of underlayment (My Top 5) under a rug or carpet. It is hidden from sight, and it does not add much bulk at all. More importantly, it helps reduce sound transmission in a very effective way.

Since it is going on the floor, there is no need for traditional adhesive or anything like that. All a person needs to do is let gravity do most of the heavy lifting, and it will be an effective solution without question.

Sound Deadening Paint or Spray


A paint or spray might not seem like it could do much, but there are also plenty of people who have counted on it throughout the years. It is usually used with some other solution.

A person will not notice a huge change overall, but there will be a slight STC point increase just by using the product. Like any spray or paint, multiple layers can be added for people who want to see a change as well.

Sound Decoupling

One of the most effective ways to soundproof a room is to discover the materials that are causing sound. There are products to help specifically with the decoupling, and are essential for effective treatment.

Resilient Channels


The goal of resilient channels is to provide rails that go across the studs of walls and the joist of ceilings. They go over soundproofing insulation, and this allows for the drywall to be attached directly to the resilient channel. By avoiding the studs, a personal notices that it is a much quieter solution.

Some people will do resilient channel insulations by themselves, while others will hire a professional. With resilient channels in place, people will notice a worthy upgrade overall.

Soundproof Drywall


Basic drywall has a certain level of soundproof effectiveness built-in, but something that is specifically soundproof is extremely effective. It is pretty easy to combine several layers of gypsum board together, which increases the density.

Some people do not like that soundproof drywall is more expensive, but homeowners will find it worthy of an investment. As long as a person knows what they are getting into, they can either buy soundproof drywall for a particular room, or the entire home.

Soundproof windows

A permanent solution to windows being a little too noisy is upgrading them to something a little more soundproof. Going with a thicker pane of glass is one of the most effective ways, and having two panes can help trap sound waves coming in and leaving a building.

A good thing about soundproof windows is that they can go right over the top of existing windows. This cuts down on insulation costs, but if a person is building something brand new, they might want to start with soundproof windows from the beginning. They make a huge difference overall, and they are becoming the standard in a lot of ways.

Noise Proofing Compound

The final product that works with sound decoupling is a noise proofing compound. Green Glue is the most popular product in this range, but there are some competitors out there as well.

A person needs to apply The compound between the layers of drywall, or any other surface for that matter. It helps to kill sound vibrations that normally pass-through surfaces.

Green Glue (Amazon) is also a solution that can help seal up smaller places that need assistance. For example, if there is a hole or gap in a wall, Green Glue will help close it up. It just takes one small area that is vulnerable to make it challenging to soundproof everything.

What Soundproofing Solutions Doesn’t Work?

With people looking for the perfect solutions out there, some are less than stellar. In fact, some people fall for some solutions that do very little, and it ends up being a waste of time and money.

Thick carpets and rugs

There is nothing wrong with getting a thick carpet or rug to help with soundproofing, as they will be more effective than something that is extremely thin.

That being said, going with only a fixed solution and nothing else is not going to make that much of a difference. The real difference-maker is putting something underneath that can help with soundproofing.

Taking some soundproofing material and putting it underneath carpet and rugs is way too simple not to do. There is no intricate installation process, and it takes minimal effort to place it down and go from there. Once everything is installed, there is no need to do any regular maintenance, as the material will do its job time and time again.

Egg Cartons

This might be the biggest myth in all of soundproofing. This might look like it could be an effective way to soundproof an area, but egg cartons do very little to help out.

It does reduce a little bit of noise bouncing around the room, but so does just about any softer material out there. It is not an effective way to kill sound at all, and it looked pretty tacky when put up on walls.

The good news is that acoustic foam, and similar-looking products, are all much more affordable than they were just a few years ago. This means that people do not need to rely on egg cartons, because this will do the trick just fine.

Spray Foam or Sealant

Think of this as a quick fix only. While it can be an effective way to help out in the short term, never look at it as a long-term solution. It is usually not applied all that well, and it starts to break down pretty easy as well.

Any Hard And Flat Mass

The general thought is that any mass is going to help with soundproofing. That is true to a certain extent, but make sure that it is not another flat surface.

Wood is something that reflects noise pretty easily, and it is not going to do much at all to help with the acoustics in a room. There might be less of a chance of sound creeping through, but the acoustics inside will involve a lot of echo.

Softer material is almost always going to be the better solution for sound control. It is a way for the sound to become stopped in the tracks. That is why even adding something like fabric furniture can make a huge difference.

A final look at soundproofing material

Materials for soundproofing can be pretty costly, but most people will get what they pay for if they do their research. There are quite a few solutions out there that work just fine, and no one should feel too much at risk about spending a lot of money on other solutions.

There is a lot more knowledge of soundproofing in general, which helps people sift out items that do not work. Make sure to read reviews on particular products to see how others have used them to their advantage. This is usually an excellent starting point for people who are not quite sure how to get started.
