Dynamat vs Hushmat: Automotive Sound Deadening Product Review

All of us like a good road trip every once in a while. However, the noise of the car engine and the sound of other traffic can often be distracting and impact the experience we have while on the road. This can be even worse driving through the city, as there’s more traffic and possibly the sound of construction in some areas.

While there are some cars that offer more sound protection than others, their acoustics can still be much worse than we would like. As a result, noise can often echo into the car and prevent us from enjoying the ride, especially if we’re listening to music.

However, that doesn’t need to be too large of a problem, as there are a few ways that you’ll be able to overcome it. One of the most popular of these is automotive sound deadeners, which have become increasingly common among many car owners.

During this time, there have been a few of the products that have been much more popular than others. The two more well-known are Dynamat and Hushmat, with both offering a variety of pros and cons.

As effective as these can be, the majority of us might struggle to choose between them. If that’s the case, then there are a few things that you should consider when picking one. By doing so, you should be able to make a wise decision about which one will be better for your car.

An Overview Of Dynamat


Dynamat is a sound deadener that already includes an adhesive, so you should have no problem applying it to your car. Alongside this, there are a few other features to take advantage of, including the fact that it’s heat-resistant.

Coupled with this is the fact that it’s aluminum-coated, so it should be able to put up with a significant amount of wear and tear. This should mean that it doesn’t need to be replaced too regularly, which is something that the majority of drivers will want to take advantage of.

These two features also mean that it should be quite safe to install and use in your car. There’s also a certain amount of flexibility, which should be helpful when you’re applying it around your vehicle, making it quite quick and easy to install.

While Dynamat can come in a variety of dimensions, you’ll often need to cut it to make sure that it covers areas perfectly. However, this could be more difficult than you might have thought, which could mean that you’ll have to spend more time when doing so.

One of the last main benefits here is that it doesn’t have an odor, which can often be quite a large problem with many car sound deadeners.



How Effective Is It?

Dynamat has long been one of the more popular sound deadeners for cars, with this being driven by each of the benefits that it offers. However, the main reason that this has been the case is how effective it is at soundproofing a car, with this outperforming many of its competitors.

Typically, you might expect to use several layers of a product to see the positive effects that it has. This shouldn’t be the case with Dynamat, as you should notice the difference in sound after installing the first layer. It should also have an impact even if you’ve only partially covered parts of your vehicle.

To do so, however, you’ll need to make sure that you’ve covered the right areas, which can often vary from car to car. Since it’s thick and coated in aluminum, you should also expect it to last quite a significant amount of time. As a result, it should stay effective without needing to be replaced too often.

In the majority of cases, you should be able to see a noise reduction of between 10db and 18db, although you’ll need to cover the entire cabin for this to happen. If you’re going this route, then it could be much more expensive than you may have initially thought.

How To Install Dynamat

Naturally, many of us will want to know how to install Dynamat, especially if we’re doing it ourselves instead of hiring a professional. While this is relatively straightforward, it can take much more time than you may have anticipated, as it can be quite challenging to cut through.

This is mainly driven by how thick the product is. While this helps to make it as effective as possible, it also means that you’ll have to spend more time than you may want to install. However, since it already includes an adhesive, you should be able to save a certain amount of time when applying it.

It’s recommended that you ask an expert for help with this, or get somebody who already has a certain amount of experience doing so. This should help cut down on the time investment that’s needed while also helping to avoid any of the mistakes that are typically made when installing car sound deadeners.

How & Where To Use It

There are a few areas that Dynamat can prove to be useful, with this extending far beyond just soundproofing. In contrast, there are a few specific uses that you should be able to take advantage of. While reducing the vibrations that are felt when you’re driving is another key benefit, there are a few places outside of your car where it could prove useful.

Some of the most notable of these are:

Dynamat can be quite useful in soundproofing a large number of areas, with many people noting how effective it can be in a variety of areas. This could make it a well-recommended choice for home theaters and gaming rooms, among others.

Because of the price per square foot, however, you may find that these are relatively expensive options to take advantage of. As such, it could be better used in smaller areas, unless you want to pay much more than you would with alternatives.

This is primarily because Hushmat has a habit of coming off quite easily when you’re driving. You should be able to minimize this as much as possible by using a high-quality glue.

Where To Use It

One of the primary benefits of many car sound deadeners is that they can be used in a variety of areas, with many of these being unrelated to your vehicle. 

However, the Hushmat doesn’t offer as many of these uses as you may have thought, as it can be much more limited than Dynamat.

However, there are still a few areas that you’ll be able to use it for, including a variety of trucks. Alongside this is the fact that there are several kits made specifically for boats, RVs, and more. While these might be slightly more expensive to buy than a typical kit, they can be more effective, depending on which vehicle you’re using it for.
