Soundproofing your car is a crucial part of customizing, especially if you love a calm and quiet moment on the road. It is also an excellent move if you want to listen to music with minimum interference.

We bring you an in-depth analysis of sound deadening solutions for vehicles and review the best materials to use.

Why Do Cars Make So Much Noise?

The noise comes from various sources. The first source is the vehicle’s moving parts, such as the wheels or the engine. The other source is the external sounds coming from the surroundings and reaching the car via spaces like the window.

Old and faulty cars produce a crackling or rattling sound depending on the rate of wear and tear.

What are Sound Deadening Materials for Cars, and How do They Work?

Your answer to car noises comes in two primary forms; sound blockers or sound absorbers. The former prevents the entry and exit of sounds, while the latter absorbs the noises, as its name hints. You may use sound blockers and absorbers in tandem for effective noise cancellation.

What to Look for in Sound Deadening Materials?

You have to consider several factors when picking a suitable soundproofing material for your car. We will look at these factors to guide you to a befitting product.

Type of Sound Isolation

We earlier talked about sound-deadening materials and how they work in beating noises. You have the choice of either sound absorbers or sound blockers.

You will realize that car soundproofing materials have absorption and blocking qualities for the best outcome.

Material Type

You also have to consider the soundproofing material type. There are four material types to use. The first option is soundproof mats. They are pretty popular, as they are easy to install and do a great job of masking sounds.

Mats are primarily used to cover vehicle panels. Besides curbing noises, they also insulate the car, making it warmer.

Sound dampening sprays are suitable for inaccessible areas in the car where you want to be soundproofed.

The other products are woven fiber and foam insulation, which you put under the car’s carpet or mat. They do away with noises coming from beneath as you drive.

Material Thickness

Thick sound-deadening materials, like mats, do a great job of keeping noises away. However, you may go for thinner material for easy installation if the panels do not need much noise insulation.

Also, there is the option of multilayered products, which works as well, or even better than the thicker single-layered ones.


Go for a soundproofing product that is enough to cover the area you are dealing with. The quantity may vary depending on the material you are using. For instance, you can use up to 8 square meters of material for a sedan or around five cans of sound insulation spray.

Some producers roll or cut the mats into sheets. In order to determine whether it is enough, look at the dimensions of the container.

When choosing solutions for your automobile that will provide sound insulation, price is another important factor to consider. Although expensive, premium goods deliver satisfying outcomes. Work within your financial constraints and choose a utility that provides the most value for your money.

Sound Deadener Installation Tools

While you can install the sound deadening material using your hands, it is better to have specific tools for a good outcome. The problem with using hands is that the adhesive matter can be messy to handle. In addition, the material may have a strong scent that will linger for a long time.

The following are some of the tools to have when installing soundproofing utilities on your vehicle.

An Application Roller

For the mat to stick firmly, you need to apply pressure. You can press it using your hand, but you may have some creased spots. The solution is to have a roller.

After laying the mat, you move the roller over its surface until it becomes smooth and firm.

The rollers come in various shapes and sizes. You may encounter flat or ribbed ones. Pick a preferable roller as per the application.

A thing to know is that you have to get it separately most of the time. However, you may find it included in the package of some sound deadening mat brands.

Adhesive Material

The adhesive material is the other item to pull out of your sound deadener installation toolkit. It can be glue or tape, though glue works better. You apply it on one side of the mat and set it on the panel. You can apply some pressure on the material for firmness.

The good news is that most manufacturers of this car accessory are producing self-adhesive types; therefore, no need for adhesive material. However, have some nearby in case you have folded edges.

Protective Gear

You also need protective gear, especially if dealing with sprays or other materials with a pungent smell. Get some goggles and a mask to protect yourself from irritating fumes.

A pair of gloves will do justice to your hands, mainly when dealing with the self-adhesive mats, which can get messy.

Step by Step Guide to Installing Sound Deadening Material

Installing the car sound insulator is challenging for many people and some resort to handy persons. The problem is that giving the job to someone else can be costly. If you want to save some bucks, you take the job as a DIY engagement.

Let us take you through the steps of installing noise-masking material for your car.

Step 1: Inspecting the Car

Start by inspecting the weak points of your vehicle that let in noise. It is easy to know the origin of the nuisance when driving. Mark out the areas to help you look for an ideal product. For instance, if it is engine noises or vibrations, you will need a mat. A spray will be an excellent option if the noises come from the wheels.

You now get the tools for the work ready. Get the soundproofing item and the installation tools to begin the job.

Step 2: Prepping the Car

The next step is preparing the car for soundproofing. Clean the vehicle with more attention to the panels you will insulate. Cleaning aids in making the insulator have a firm grip. Take the car outside or in a well-ventilated area if using a spray or a mat with a pronounced smell.

For replacements, ensure you thoroughly remove the remnants of the old mat. Scrap it with a knife or a similar bladed tool.

Step 3: Setting the Sound Masking Material

Onto the main event, you unleash the noise insulator. A self-adhesive utility is ready-to-use. You peel the backing paper and lay it on the surface you are working on. Use a roller to strengthen the grip by repeatedly rolling it over the mat.

If it is not self-adhesive, you will require adhesive material. The glue should be liberally applied to the surface without going overboard and making a mess. Place it there and apply pressure with a roller. If you don’t have glue, use duct tape.

When dealing with tight areas that you cannot readily access, a spray is an ideal solution. Shake the container first, then lightly mist the substance onto the surface of the car.

After the first layer has dried, apply additional coats.

Once finished, leave it alone for around 4-5 hours to rest. You may paint over it when it dries.

You now have a soundproofed car with minimal noises coming in. Frequently check on this car accessory to ensure that it is in great shape.
