I’ll admit it; when I began searching for ways to make my vehicle quieter, I initially overlooked all the different ways this could I could do this.
Like most of you reading this right now, I didn’t know why someone would need to soundproof their vehicle. Especially in this day an age if the car were new or at least only a few years old.
After doing a lot of digging and talking to various people that have used all sorts of sound deadening material for cars; I’m also going to answer some of the most frequent questions people have about sound deadening products for vehicles:

I will first begin by listing some of the best Sound Deadening material for a vehicle. Automakers do not typically consider soundproofing and sound dampening a necessity unless it is a luxury car.
If you’re in the process of learning how to soundproof a car, then this section will be for you!
Soundproofing a vehicle is not only to block noise from coming in but also to make the vehicle sound better while diving.
There are many ways to soundproof your vehicle, but there are no better ways than introducing a good sound deadener to get the job started.
Noico 80 mil Car Sound Deadening Mat (Best Value)

Coming up at number one for the best value to quality is the Noico 80 mil car sound deadening mat (Amazon).
The Noico sound deadening mats is tough to beat when shopping around for an effective soundproofing material for a vehicle.
As I’m writing this article, coming at $ 1.77 per 1 sq ft, Noico 80 mil is currently the best price for an 80 mils automotive butyl and foil sound deadening on Amazon. This stuff not only works great but is also very cost effective!
This automotive self-adhesive insulation consists of butyl. The total weight of the Noico audio insulation material is 0.7 lbs/1sqft.
There is also a special indicator making it next to impossible to improperly install this product. The indicator embossing on the foil section has to be rolled out with a special roller until the sheet is entirely smooth. You will then be 100% sure the insulation is correctly installed.
What Buyers Have to Say About the Noico 80 mil
I wanted more reassurance when choosing the Noico 80 mil. I not only listened to what some experts have to say; but also what regular buyers thought about the product.
Noico 80 mil Sound Deadener Buyers Review;
One person on a Reddit forum claimed that he Installed the Noico 80 mil in his 2007 Toyota Rav4. 36 sq feet is sufficient to do all the doors, the back hatch, rear side panels with some leftover.
On the doors, he opted to do the inside of the outer door skin in addition to the inside door skin. He bought a small butane blow torch from Amazon and utilized it to warm up the product after application. This enhances bond as well as makes rolling it less complicated.
You likewise require a small roller (obtain the wooden roller if possible) to apply this stuff.
Reducing this is easy; make use of a utility knife or a set of Emergency Medical Technician shears. Ultimately, wear hand protection. He used two layers of surgical gloves because the material is sticky and can be a bit dicey to wash off.
He claimed that he is surprised at just how much quieter his automobile became after the application of the sound deadening material. It felt as though the Rav4 had no sound insulation before.
If you are very fussy and meticulous, anticipate spending about 2 hours per door if you want it done right.
Road noise and also noise from passing vehicles is lowered by a noticeable amount.
The Noico 80 mil works by altering the frequencies of the acoustic waves. It is not essential to cover 100% of the doors. 25% to 50% protection suffices.
As you work to install the noise isolation mat, you can tap or thump the doors to check on your progression.
Doors close with a strong thump much like the door of a Lexus or BMW. There are fewer rattles than previously and the stereo sounds much better than before.
Some Tips While Installing the Noico 80 mil Sound Deadener
Here is a small list of tips that you might find useful while working with this product.
- As someone that has used the Noico 80 mil sound deadener to soundproof an older vehicle, 36 sq ft was enough. I did four doors and the floor of my friends older model Toyota Corolla. Two sheets (8sqft) were left over that I added inside the panel of the trunk.
- If you use a sheet of paper to form a template before cutting the sheet, make sure you have it on the right side up. You can not just flip it over once you cut an irregular shape.
- This product does not stretch whatsoever. Be sure to push it into curved shapes as you’re laying it out in preparation; not while you’re rolling it into place.
- Larger pieces of the Noico noise isolation sheets are much preferred over a bunch of smaller pieces.
- You should keep in mind which holes in the metal are significant vs. which you can cover up with the sound deadening material.
- Remember that you’re trying to roll out all of the air bubbles. Begin rolling from the middle towards the edges to let the access air out.
- If you do happen to miss a few air bubbles, cutting an exit hole is perfectly fine. Leave the blade in the hole while rolling the matt out because of the butyl material being self-sealing.
- Be careful handling the foil edges of the sound deadening mat. They are sharp and can cause minor cuts on your fingers.
How to Instal the Noico and Most Butyl Sound Deadening Material
Please thoroughly check through the entire manufacturer instructions from start to finish. Familiarizing oneself with all the information is important. The effectiveness of soundproofing doesn’t just rely on the product you make use of but mostly is an outcome of the correct setup and execution.
Please note that incorrect installation could bring about unfavorable results or no soundproofing impact whatsoever.
STEP 1
Decide what part of the car you intend to apply the noise isolation material; floor, roof, doors, trunk or firewall.
Treatment of each steel part of the vehicle has its unique benefaction to the general results of the project. Keeping that in mind, I would advise you to soundproof all of the metal sections of the vehicle for optimum efficiency.
Next, locate the owners manual to your specific automobile. Find the section where it explains how to take down the trimming panels.
You ‘d have to be careful when taking off the panels; as well as prevent damaging or misplacing the fixing clips when it comes time to install the panels. That kind of info could be additionally discovered on an appropriate automotive online forum.
STEP 2
Try your best to remove all of the factory insulation once trimming off. You just need to do that if the noise isolation insulation from the manufacturer shows signs of wear, damage or has not been adequately mounted. But You can certainly leave it there if it’s still in good shape.
STEP 3
Properly clean and de-grease the surface area before applying the sound deadening material.
If the surface is damp or dirty the material will not adhere to the metal surface properly. You should make use of a degreaser if there is any sign of grease on the surface area.
Make sure to wear the proper protective clothing (Gloves) and to do this in a well-ventilated area.
STEP 4
As soon as the third step is complete, measure the potential surface that you are most likely to apply the noise isolation material.
A quick suggestion for you is to make a design template of suitable size on paper initially; Then afterward transfer it to the sound isolation mat. That will certainly help to put it properly and avoid wasting material.
Use a stationary blade or a pair of sharp scissors to cut the mat down to size.
STEP 5
Next, put the deadening mat to the surface area without removing the protective foil coating.
Ensure that it covers the surface area adequately. You’re now ready to remove the protective foil coating slowly. Make sure not to pull it off too fast. Slower is better to ensure better adhesive effectiveness.
As soon as the sound isolation material is appropriately on the surface area, press it down firmly and let it glue.
Flatten the sheet with your hands. Try your best to avoid creating air bubbles between the self-adhesive mat and metal surface.
Use a rolling tool to press the mat down to the metal surface by rolling it from the center of the mat outward.
The Noico 80 mil sound deadening mat has unique dimples-like foil embossing on the surface of the mat. The embossing allows the user to recognize which spots will need more pressure.
You will have to roll the mat down until the dimples in the foil texture become smooth and flat until correctly installed.
Dynamat Thick Self-Adhesive Sound Deadener (Best Results!)

The real question in all of this is what is the best sound deadener for a vehicle? I believe we’ve found the one that should hold that title.
It does, however, cost more than the Noico sound deadener; but you also get what you pay for with the Dynamat.
I did a fair amount of research before concluding that Dynatmat is, in fact, the best sound deadener for a car on the market today. This is, however, my professional opinion; and might be disputed by some of you that have had success with other sound deadeners.
If you do a bit of research, you will certainly also see that some people chose to apply roofing tar from the local hardware store instead of a specifically made noise reduction mat.
I would think that you would be out of your mind to stick some tar on the inside of your car in hopes of reducing road noise.
Not only because it wouldn’t do a great job at sound deadening, but it would also be a health hazard. Inhaling the toxic fumes stuck in the vehicle’s cabin are probably not the best for your overall health.
The only negative on this product is the high price. But you can certainly save some money by buying in bulk from Amazon.
Dynamat Installation Process
I completely transformed the trunk of my friend’s car (our test car, 2007 Toyota Camry) into an enclosure with Dynamat sound deadener. We covered pretty much every metal surface I could get my hand onto. I did also double up on Dynamat on a few crucial spots.
I calculated that by only doing the trunk and doors you would need between 50-80 square feet. It would, of course, depend on the specific vehicle you’re attempting to soundproof.
You can most likely find out how much Dynamat sound deadener you would need for your car by browsing the question/answer section of this product on Amazon.
If you’re looking to also soundproof the floor of your vehicle, then you would probably need around 100 square feet of this product.
I would certainly use the bulk kit for anything except the doors. You can certainly use the Dynamat in the bulk kit on the doors, but using the door kit strips 12″ x 36″ would result in a much cleaner install since they cover the entire length of the vehicle’s doors.
Helpful Tip While Instaling Dynamat Sound Deadening Mat
Another good thing I can recommend is using heat if possible for applying the Dynamat sound deadener.
Dynamat does state on their website that you do not need to make use of heat during the application process. I found that I was able to put the Dynamat down much flatter by adding some heat into the mix!
The heat is also nice when applying the Dynamat with your fingers. You do this while trying to get into those hard to reach spots where the roller isn’t an option.
I did refrain from using heat on the doors because it could damage some electronic components. Dynamat does say heat is not needed, so there is no need to risk damaging the internal wiring.
HushMat Ultra Black Foil Bulk Kit with Damping Pad

When it comes to heat endurance, and it’s sound deadening effectiveness, Hushmat Ultra Damping Pad (Amazon) is very comparable to its rival Dynamat. Hushmat is a solid deadener which works as an excellent sound isolator.
This butyl-based product has great heat-resistant and is perfectly safe for installing in your car. One more comparison to its many rivals is that it comes in numerous types of kits. The kits for Hushmat can range from bulk, as in doing the entire vehicle, doors only or floors only.
Being able to choose a kit will prevent waste. This is a very cost effective solution to your noisy vehicle.
Speaking about cost-effectiveness, I would consider Hushmat quite affordable at approximately two dollars a square foot. When comparing to Dynamat, it is a cheaper alternative.
This price point however only applies for the complete Hushmat sound deadening kit.
You will be shelling out around four dollars a square foot for the door and floor kits. Keep that in mind while shopping around for the best deal on sound deadening products.
How to Instal Hushmat In Your Car
Unlike other noise isolation products on the market, Hushmat is one of the easiest sound deadening mats to install in a vehicle. The reason why Hushmat is easier to install is because of its thickness, or should I say the lack thereof.
Hushmat is very thin and is almost unnoticeable after proper application. The fact that this material is thin makes it incredibly flexible and easy to work with compared to some of its competitors.
The installation process works like most sound deadeners with its self-adhesive abilities (follow steps above).
All you need is a pair of household scissors or a knife, and you’re all set. Anyone with even the least DIY abilities would be able to install Hushmat without any problems.
Make sure to apply any self-adhesive mats in a “room temperature” environment and not when the metal is cold.
If the car is cold the self-adhesive bond will not be as strong and could peel off down the road.
Other Automotive Sound Deadening Material on the Market to Consider
Now that I’ve talked about the Top three automotive sound deadening material; it’s now time to talk about the ones that aren’t as popular but could still good contenders.
Some of these noise isolation material is made primarily for heat shielding; but also produces some impressive noise reduction capabilities.
Just because some of these materials and brands are lesser known should not be a reason to overlook them.
There are several different thicknesses of Dynaliner to chose from, but they are very thin when comparing to other vehicle sound deadeners on the market. The thinnest Dynalier comes in at 0.12 inch while the thickness Dynalier sheet is around 0.45 inch.
Some people use the thinner sheets to reduce vibrational noise coming from different areas of the vehicle such as a subwoofer.
I’ve even read that one person installed this sound deadener on their vehicles gas tank due to vibrational noise. He claims that it works great for that purpose.
Dynapad is a bit different from Dynaliner because this sound deadening mat is not self-adhesive. The perfect place to install Dynapad is along the floor of the vehicle where it will combat not only noise but also heat.
The fact that Dynapad is not self-adhesive makes it an easy install on the floor. But only if you’re placing it under the vehicles carpet or rubber flooring.
B-Quiet Viscoelastic Sound Deadener
The B-Quiet Viscoelastic Sound Deadener (Amazon) is very flexible, odorless, heat-resistant and works very well as a sound deadener. Incredibly the B-Quiet is not butyl but has all the characteristics as a butyl deadener.
I was reading through the manufacturer’s description, and they say that this product should be used in conjunction with another sound deadener.
They suggest using their B-Quiet Extreme alongside the Viscoelastic sound deadener; Im still trying to figure out if this is a sales tactic or if the Viscoelastic is just not good enough on its own.
