1. Dynamat Auto Sound Deadening Material


First on our list of best sound deadener car reviews is Dynamat.

Dynamat is one name that is widely known for its effective auto sound deadening. Made of butyl, it offers durability, great effectiveness in automotive soundproofing, and provides heat resistance too.

So you can be sure of significant noise reduction with its use. Its heat resistance properties also make it useful in keeping the heat out of your car’s interior.

Many car deadening products are known to emit odors when used under high temperatures, but that’s not a thing to worry about with Dynamat.

It’s fit for use no matter the weather condition. Despite its thickness of 0.067”, it provides you with unparalleled results due to the high-quality materials used in its construction. 

Dynamat’s size of 36 ft2 means you can save more by covering much more with a single sheet. So instead of buying so much, you can get the job done with only a few.

Apart from its use in soundproofing your car, Dynamat can also be used in your home to soundproof your home theater.

This makes it very popular but its efficiency makes it very expensive. Also, Dynamat isn’t the cheapest option in the market and is not the best option for those who are on a tight budget.


  • A quiet car sound deadening material
  • Has good heat resistance
  • Can be used under the sun without odor production
  • Has a generous size
  • Versatile usage

It’s a thermal and sound insulator and helps you achieve even better results with your Dynamat sound deadening mat.

It’s an acoustic foam of closed-cell rubber and measures 0.25” thick.

This thickness is adequate since its meant to be used with Dynamat. It’s also durable and would serve you for a long time.

Since Dynaliner is primarily for heat insulation, you would want to install it in places where the heat gets in, such as in-car doors, under the hood, and on the roof of your car.

Dynapad is a heavy material made with two layers of open-cell acoustic foam and a vinyl base in between. It has a thickness of 0.45” and is good for the thermal insulation of your vehicle.

It’s also great at automotive sound deadening and in improving the internal acoustics of your car, especially when used together with Dynamat.

Due to its weight, it’s best installed on the floor of your car, under the carpet. You can also install it under your car seats and in the trunk of your car.

2. Kilmat Auto Sound Deadening Material

Second Best Vehicle Soundproofing Material

Next on our list is the KilMat Auto Sound Deadening Material.

It’s also made of butyl, so you can expect great performance there in terms of noise dampening and heat resistance.

So the installation and use of Kilmat not only provides the interior of your car with quietness, but it also works to keep the heat out for even better AC performance.

Just as with other butyl based mats, Kilmat produces no smell when used during a sunny day, so be rest assured that your drive won’t get uncomfortable at any point.

It also has an aluminum foil backing to further improve its durability.

The thickness of Kilmat is an impressive 0.08”, making it an even better sound deadener than most products in the same category.

This thickness doesn’t imply difficulty in use as it’s lightweight so you can install easily, but heavy enough to absorb noise.

Installation is made even easier with the indicator and gives you the satisfaction of perfect installation when done.

The sizes of 9.8” x 15.7” makes it even easier to cut and install. At a size of 36 ft2, you can be sure to cover a lot with a single package.

3. Noico Automotive Soundproofing Mat

Best Cheap Car Sound Dampening Material

Noico is one of the best sound deadening materials for your car you will find in the market.

It offers great performances like the top names, but what makes it even more appealing is that it gives you more for a cheaper price.

Made using butyl rubber, and with a thickness of 0.08”, you can expect nothing short of the best in terms of effectiveness.

Noico isn’t purely made of butyl as it has an undercoat of asphalt.

Asphalt is also a sound deadener but not as effective as butyl.

It’s also less resistant to heat so it smells under the heat of the sun. Since Noico is mostly made of butyl, it offers good heat resistance too, but you will notice a bit of rubbery scent with use.

Noico is pretty thick at 0.08”, and that’s one of the reasons it performs so well. This is accentuated by its weight of 0.07 lbs/ft2.

Despite this thickness, Noico is pretty easy to cut and install, so you get a good user experience from the start.

It also has good size and favorable dimensions so you can adequately cover your car for the best result.


  • Made majorly of butyl rubber
  • Has adequate thickness
  • Effectively deadens noise
  • Good heat resistance
  • Easy to install
  • Cheaper than most sound deadening car products

4. HushMat Auto Soundproof Pad

Easiest Installation

Next on our list of best car sound deadening materials is the HushMat sound deadener.

It’s a butyl based product and offers great sound dampening with good heat resistance.

It’s also comfortable to use as it doesn’t give off a rubbery smell in the sun, so your ride can be pleasant to the end.

It’s also durable and would serve its purpose for a long time.

Its thickness of 0.06” means it’s fairly thin and less effective than some mats in the same category.

The quality of material used in its construction is what gives it an edge nonetheless over other mats. The thinness however makes it easy to cut and install.

HushMat comes in a small size, so you would need to make multiple purchases to properly soundproof your car.

It isn’t much of a problem though as it’s affordable. The adhesive used on the mat is another problem as the mat has been known to fall off during a bumpy ride.

This problem can however be fixed with the use of a stronger adhesive.


  • Effective sound dampener
  • Can withstand high road temperatures
  • Odorless
  • Easy to install
  • Durable mat


  • It’s thin

5. FatMat Automotive Soundproofing Mat

Last on our list of car sound deadeners is the FatMat self-adhesive mat.

It’s a great option if you are looking for a mat with good thickness, easy installation, and great performance.

With a thickness of 0.08”, and made of asphalt, you can be sure to reduce road noise noticeably.

Being asphalt-based, its effectiveness isn’t as good compared to that of other butyl based products, but it makes up for that with its thickness.

Its design and composition are such that the interior sound remains, while the exterior noise stays out.

FatMat has heat-insulating properties, which allows it to absorb external heat so your car’s AC can work even better.

The downside though is the rubbery smell it has especially in the heat.

This can be uncomfortable for some users so be sure it won’t be a problem for you before you make the purchase.

The rubbery smell also limits its use to areas of cold weather.


  • Adequate thickness
  • Good effectiveness
  • Easy to install
  • Heat resistant


  • It has a rubbery smell especially when used in the heat

Type of Material

There are different materials used in the construction of car sound deadeners, and they work to absorb vibrations and sound waves.

  • Sound deadening mats are the most popular because of their performance. They go beyond just absorbing noise to also absorbing heat.


  • Foam insulation and woven fiber products are other types of materials that can be used to deaden the noise in your car. You can use them under your carpets and floor mats of your car.


  • Sound dampening sprays are another fairly popular option for use in keeping the noise out. They are not used regularly because they are not the easiest to install. 

The use of mats is highly recommended as they deliver great performance and ease of installation.

Interaction with Heat

While some sound deadeners are heat resistant, others don’t do well when exposed to heat. They can tend to melt and release unpleasant smells in the face of heat.

So when making a purchase, go for a product that can withstand heat especially if you live in hot areas.

Size and Cost

If you are opting for mats, go for one that is fairly large and can soundproof your car without the need for multiple purchases.

The idea is to save cost so except you see smaller pre cut pieces for a cheaper amount, going for smaller sizes would be more expensive.



By soundproofing your car you maintain the peace you deserve after a long day at work while you drive back home despite all the traffic noises around you.

You’ll also ensure that the quality of music from your stereo isn’t compromised by outside noise. All of these can be achieved easily by the installation of the best car sound deadeners.

Dynamat is the best product for you if you need great performance and are not on a tight budget. Kilmat is also effective and a bit cheaper option compared to Dynamat, so if you are on a budget you can choose this.

Noico is for you if you are looking for the easiest to install mat.
