How To Soundproof A Car: 8 Effective Ways

There are several methods of soundproofing a car you can consider based on the efforts and money you want to invest as well what results you expect. You can choose one of the following methods and start soundproofing your room.

1. Insulate The Doors

A lot of cars have very thin doors with less insulation that have a lot of cavities inside which will lead to transmitting noise in the car through the doors.

So insulating car doors can have a very big impact on the amount of noise you hear in the car. to insulate the car doors all you need to do is to take out the panels and unscrew that which will expose the interior of the door.

After it is exposed you need to clean the panel thoroughly with rubbing alcohol and measure the area for insulation material. If you go wrong with the measurement there will not be enough insulation on the door.

Always choose the insulation material with a sticky background because that will cover the surface thoroughly and perfectly. Also, flatten the surface with the help of a roller by rolling in and out it will fit the sheet and remove bubbles.

Ensure that you cover the complete door with insulation material for effective noise blocking and you need to repeat these steps for all four doors. Then screw back the door panels and you’re done with soundproofing the car door.

Sound deadening car mats are one of the efficient and effective ways to soundproof car floors. They not only soundproof the car floor but also reduce vibrations.

These mats are placed on the cabin floor in both front and back to block out the sound and vibration your engine and exhaust make. They are very easy to install just take out your sound-deadening car mats. Place the mats on the floor and you’re done.

However, you should start soundproofing with the car doors that will not only reduces the noise but also makes the car acoustic. Soundproofing the Sound system speakers will increase the sound quality.

Automotive sound deadening mats can be applied over car cabins, roofs, and trunks for better soundproofing. We have already covered a guide on dynamat sound deadener. I recommend dynamat sound deadener for soundproofing.

3. Use Soundproofing Car Spray

The surface where you want to apply should be cleaned thoroughly and before the application and the process is simple just spray and cover the area with the spray.

The soundproof spray is effective for small gaps and surfaces but doesn’t use on the complete cabin because it’s effective with other sound-deadening materials.

If you want effective results then add layers of spray. All you need to do is apply the spray and leave it to dry after that add another layer of spray that will be denser and thicker for effective sound blocking.

Replacing the seal on doors and windows is one of the effective ways to soundproof. Any gap even the minor will let the sound inside your car. sealing this will block out the sound.

Most probably the noise which we hear is the wind noise which is transmitting through the gaps inside the car. replacing seals on doors and windows will bring a massive change in reducing noise if the noise is much.

If the rubber around the windows or doors gets worn and torn then it’s time to replace it because the noise is transmitted through it. This will cut down the wind noise.

Installing a rubber seal on the doors and windows is pretty easy all you need to do is just put adhesive and place the rubber seal and press thoroughly to make sure the adhesive dries up before you shut the door.

5. Soundproof Tires

Your car tires will impact a lot on the noise you hear in the car. tires are the only part of the car that will be in contact with the road and all the sound vibrations in the car are because of wheels impacted.

Some tires even cause a car to make a squeaking noise while turning. Changing your car tire will impact a lot on the noise you hear. Replacing the existing tires with soundproof tires is the best option to choose without soundproofing the existing tires.

Soundproof tires have acoustical properties that will reduce the noise and vibration which is produced on the road. Tires with less profile are not all are effective in blocking road noise.

Simultaneously tires with the maximum amount of rubber between the car and metal wheel are the best tires for blocking out road noise they provide cushioning against road vibrations.

The newer car has large wheels and very less profile that is not effective enough to provide cushioning against road noise and vibrations. Make sure you select a tire with maximum rubber between the car and the metal wheel.

6. Soundproof Car Trunk

If you’re on a long drive if the car trunk makes a noise that will annoy you and the people in the car. this will also lead to accidents because constant noise will annoy the driver and shift the focus from the road.

While driving with the family it will kill the joy of driving and makes your trip unpleasant and give headache that’s why you need to fix it. hearing the noise for a long time then it will negatively on the driver.

To soundproof the car trunk all you need to do is take out the like carpet, subwoofers, trunk cover, deck, and so on. After taking all the things you need to clean the surface thoroughly with the detergent and leave it for some time to dry up.

If you skip the cleaning surface part then the material will not dampen properly and it will not be effective to block out noise and vibrations.

Now get the tools like a screwdriver, clip remover, utility knife, and a pair of gloves. It’s time to install the sound deadening material on the trunk. If you think that the noise is high then make sure to add the layers of the sound deadening material you can also use mass-loaded vinyl for extra layers of soundproofing.

Final Thoughts On How To Soundproof A Car And Reduce Outside Noise

Using only one soundproof method will not work effectively I recommend using a combination of several methods and materials. Install and apply at the same time for hassle-free work and effective noise blocking.

However, if you use only one soundproof method at a time then it will block out a few percent of the noise, and not all the noise will be cut down. Use different materials like sound deadening mats, sound deadening spray.

Always start soundproofing from doors because they will transmit the maximum amount of noise in the car and vibrations are due to floor soundproof mats will help you to reduce vibrations.
