Is soundproofing a car effective?

You may have thought of this question at some point. Often, we often associate soundproofing with rooms and studios. However, you can also apply it to your car.

Soundproofing a car, one of the things that you must remember is that you can never block all the noise from outside.

However, most of the unnecessary noises can be blocked & it will make you comfortable while driving your car.

However, these automotive sound dampening materials can definitely lessen the sounds coming in from outside your car. I can personally attest that you can only see the difference once you have experienced the “before and after” once you have installed the sound deadening materials.

Another thing that you should know is that the type of car you are using affects its ability to block noise. Newer car models are known to have better acoustics compared to older models.

If you happen to own an older car, more or less you need to check what type of automotive sound dampening materials would work best with it.

Lastly, the effectiveness of a sound deadening car is dependent on how you successfully applied the soundproofing technique. It is essential that you pay attention to the instructions when installing the sound deadening materials into the panels.

Admittedly, some of the instructions can be quite confusing, so I sought help from a professional.

How to Reduce Road Noise in Car?

01. Distinguish where the noise comes from and have your car checked

Most people will pay no mind to this part. However, there is nothing wrong with taking extra precautions before soundproofing your car.

Any engine rumble can also be a sign of issues in your engine. Before I tried installing anything I made sure that I had my car checked before making any upgrades.

Apart from that, knowing where the noise in car interiors is from will make it easier for you to choose the dampening materials that you can use for your car.

02. Choose the materials for your car

There are several automotive sound dampening materials that you can use for your car. We have dampening mats, sound deadening sprays, insulators, and foams.

These materials vary in thickness and length. Before deciding on the car materials, you need to check out what materials works best for your car. There may be some materials that are not compatible with your car model.

If you wish to do it on your own, these materials are available in the market and come with easy-to-follow installation instructions.

03. Installing the dampening mats

Step 1

Remove the car seats and car panels from your car. In this way, it would be easier for you to get the correct sizes of the dampening mats.

Step 2

Once you have the desired measurement of the dampening mats, cut and prepare them. However, if you want a pre-cut dampening mat, you should probably get the Self-Adhesive Sound Deadener.

The Dynamat 10455 makes it easier for you to cut according to your desired measurement. It is also durable because of its aluminum mesh netting.

This type of mat has better acoustics, which lessens road noise from tires and stops vibrations from your engine hood and other parts of your car.

If you wish to get a cheaper alternative, you can use the HushMat Ultra Black Foil Door Kit with Damping Pad. This mat is also a perfect dampening mat for vintage cars. It has ideal adhesive and sticks well into tight spaces and corners of your vehicle.

It’s a perfect dampening pad for your car door slam. Another benefit of this pad is that it’s heat resistant and can withstand a maximum of 400 degrees Fahrenheit. You can use this not just for your car interior but also for your engine hood as well.

Step 3

Clean off the old adhesive from the car panels. You can use acetone to get rid of the glue. The surface should not have any leftover adhesive on it.

Step 4

Get the prepared mats and attach them to the desired areas. Start attaching the dampening mats for the car panels. Make sure that you will not cover the holes for the screws and wirings.

Step 5

Grab your chosen adhesive and glue the dampening mats in between the panels. Before using the dampening mat’s adhesive, make sure that you are wearing gloves.

The adhesive glue can be powerful and might be difficult and painful to remove from your skin.

Step 6

Once you are done with the panels, place the mats for the engine hood and compartments.  You can use the Dynamat Dynaliner Self-Adhesive Sound Deadener for your engine hood.

This dampening mat is oil, water, and heat resistant. It can withstand high-intensity heat. Apart from that, this mat is also very flexible and thin.

It can easily mold itself to contours and corners of your engine hood and compartments and look less bulky in your car interior.

Step 7

Get the sound deadening spray and spray it in between the small spaces of your car. Do not forget to also spray the other smaller compartments and your engine hood.

04. Installing the Deadening mat

Installing deadening mat is one of an efficient way to quiet road noise in the car. Here are the few simple steps you can apply.

Step 1

Remove the car seats and car panels and other decorations inside your car. Then grab a pen and a measuring tape and measure the areas where you need to place your insulation mat.

Step 2

Get your insulation mat and cut it into your desired size. You can use the Car Sound Deadening Mat as an insulator and noise dampener for your car. This helps lessen vibration and external noise by up to 50%.

It is made from butyl and foil, which are effective alternatives for expensive insulation mats. It also comes in handy sizes, making it easier for you to cut and measure.

If you happen to own a vintage car, you can use the Car Insulation Mat Liner.  This insulation mat is designed for custom cars and vintage models. It has an aluminum metal and fiberglass finish that helps your car be in tip-top condition.

This does not only keep noise levels down, but it also helps regulate your car’s temperature, especially in last seasons.

It also has a strong adhesive which makes it easier to mold into your car’s crevices and corners, thus, cutting down resonance and road noise effectively.

But if you wish to have a pre-cut insulation mat, you should opt for the Car Sound Deadening Mat. This insulation mat is pre-cut which makes installing it less of a hassle.

Like other insulation mats in the market, this mat also has a self-adhesive feature which makes it easier for you to install and use. If you wish to get this one, make sure that you measure your car’s interior before buying this product.

Step 3

Make sure to clean the old adhesive from the panels and other parts of the car. This is to ensure that your insulation mat will stick firmly into the panels and floors.

Step 4

Get your adhesive glue and apply it on the surface of the panel. Then, press the insulation mats firmly into the panels. Do not forget to wear hand gloves to avoid the adhesive from sticking unto your skin.

If you happen to purchase the insulation mats that have a self-adhesive feature, press the mat firmly into the panel.

Make sure that the mats are well-fitted into the car panels.

Step 5

If you see any lumps or bubbles on the insulation mat’s surface, get a paint roller and roll it on top of the mat until the surface is smooth and level and already free from bubbles.

Step 6

Get a sound deadening spray and spray it over the small spaces in between the insula sound deadening spray on mats and other parts of the car.

If you have the right materials and proper installation procedures, you can even do it yourself without the assistance of technicians or soundproof experts.
