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.

Absorbers

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

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

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?

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.
