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.

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.

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.

Pros

  • 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.

Pros

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

Pros

  • Adequate thickness
  • Good effectiveness
  • Easy to install

Buying Guide for The Best Sound Dampening Materials for Cars

Thickness

The thickness of a mat plays an important role in the effectiveness of the auto sound deadening material.

So when considering a mat, go for one with good thickness as its more likely to block out noise than the thinner ones.

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.
