How To Soundproof Your Car to Maximize Your Driving Comfort

You’ll always hear noise, no matter what car you drive. Some noise comes from inside the vehicle, while the rest comes from outside. Thankfully, you can reduce that noise and maximize comfort by soundproofing your car.

Soundproofing your car will block vibrations and noise, giving you a more comfortable ride. You’ll need to install soundproofing materials in your car’s panels to achieve that. There are plenty to choose from, but The Canopus Sound Deadening Mat will give you the best soundproofing benefits.

This quick guide will tell you everything you need to know about soundproofing your car. First, you’ll learn what causes noise in your vehicle while driving. Then, you’ll learn how to make your car quieter so you can enjoy a much more comfortable ride.

What Causes Noise While Driving?

Before diving deeper into soundproofing or sound deadening in your car, you must first understand where that noise is coming from. That way, you’ll understand the different solutions and how they work.

All cars and motor vehicles produce noise, even all-electric ones with no combustion engines. It’s impossible to eliminate all noise completely. But as you’ll discover later in this article, there are plenty of ways to reduce noise to the point it’s barely noticeable.

First and foremost, you must understand that noise sources exist both within and around the vehicle. In other words, the car is responsible for some of the noise you hear, not just the surrounding environment.

Here are some of the noise sources inside your car:

➔ The engine bay: As you might’ve guessed, a lot of the noise you hear while driving comes from the engine bay. That’s where you’ll find the engine and other mechanical components that make a lot of noise whenever your vehicle runs.
➔ The suspension system: Some noises also come from the system, i.e. the parts connecting your car’s body to its wheels. The noises from this part aren’t as loud as the engine, but you will hear them if your suspension isn’t in its best condition.
➔ The exhaust: You’ll also hear noise from your exhaust system. That system carries gasses out from your engine towards the vehicle's rear. Unfortunately, the air that passes through also carries some noise despite being muffled by the exhaust system.

On top of that, a lot of the noise you hear also comes from external sources such as:

➔ The road: Your car moves because the wheels create friction underneath it. That friction, where the rubber meets the road, causes noisy vibrations you can hear and feel inside your car.
➔ Other cars: Aside from the road, the noises you hear come from all the cars around you. The more vehicles around you while driving, the noisier it’ll be.
➔ The environment: Lastly, anything in the surrounding environment that generates vibrations or noise will affect your comfort inside the vehicle. As well-designed modern cars are, they don’t come soundproof by default.

Understanding where the noises come from while driving enables you to soundproof your car much more effectively.

Can I Make My Car Quieter?

Yes, there are plenty of ways you can make your car quieter. In the automotive world, this process is called ‘soundproofing’ or ‘sound deadening’ your vehicle.

Here are the ways you can make your car quieter:

1) Replace Rubber Seals

First, you must ensure your car’s existing parts are in good condition. That’s because many of them, like rubber seals, are already implemented to minimize noise.

These parts wear out over an extended period, causing your car to lose its soundproofing.

For example, check the rubber seals around your doors. You must replace them if they’re loose, torn, or worn out to make your car quieter.

2) Repair or Replace Problematic Parts

As you read earlier, many car parts make some noise as part of their normal operation. That includes your car engine, transmission, and even the suspension system.

However, when they're in bad shape, these parts will make much more noise.

If you want to make your car quieter, ensure that none of the existing parts are making noise. If they’re problematic, repairing or replacing them will help to make your vehicle quieter.

3) Check Your Wheels And Suspensions

Check out your wheels and suspensions once you’ve dealt with parts in the engine bay. The components in these parts will also wear out and cause a lot of noise. That’s why you’re meant to replace them every few years or when they wear out.

New wheels and a functioning suspension system will help minimize noise, particularly from the road underneath.

4) Invest In Sound Deadening Materials

Taking care of all the basics above will reduce the noise in your car significantly. But if you want to take it further, you can invest in sound-deadening materials.

Simply put, install these aftermarket products in your vehicle’s panels to reduce vibrations further. As a result, they also reduce the noise you hear each time you get inside your car.

There are plenty of different materials and products you can choose from, with the Canopus Sound Deadening mat as a perfect example. With proper installation, products like this one will absorb vibrations and reduce car noises significantly.

What Helps Absorb Noise?

When you shop around for car soundproofing solutions, you’ll find that products use various materials. On top of that, some manufacturers combine more than one material to leverage each one’s unique benefits.

Here are some materials that help absorb noise, which you’ll find in automotive soundproofing products:

➔ Butyl: A common material you’ll find in automotive soundproofing products is butyl. It’s a type of rubber that makes it uniquely effective at dampening sound from the vehicle’s structure.
➔ Asphalt: Believe it or not, asphalt is another material that also absorbs noise. It’s a dense material with positive qualities, making it suitable for car use, dampening vibrations and reducing noise.
➔ Acoustic Foam: You might have seen acoustic foam used in studios, theaters, and other rooms. However, this material is also helpful in automotive settings thanks to its ability to trap sound.
➔ Mass Loaded Vinyl (MLV): Vinyl is another material often used in automotive soundproofing. Mass Loaded Vinyl (MLV), specifically, is thin and rubbery. That means it reduces vibrations in cars that cause the noise you hear.

You’ll often find other materials in the same products, like aluminum, that don’t absorb noise. Manufacturers use these materials to support the ones listed above in doing their job more effectively, even though they do nothing to reduce vibrations.

Where To Install Sound Deadening Material?

The type of materials you choose to soundproof your car is essential, as is their placement. Installing them in the right places will ensure that vibrations and sound won’t travel through the vehicle’s structure, thereby decreasing noise levels.

Whether you’re installing the materials yourself or getting a professional to do it, these are the parts of your car that require soundproofing:

➔ Roof: The roof is one of the largest panels on your vehicle’s exterior. It can absorb many vibrations from the surrounding environment, so you’ll want to install your soundproofing here.
➔ Hood: The hood is another part of the car where plenty of noise passes through. That’s unsurprising, considering it’s what covers your engine bay where most of the noise originates.
➔ Trunk: It might seem counterintuitive initially, but your trunk also requires a lot of soundproofing. That’s because it’s near the exhaust and the car’s rear, where plenty of noise is generated.
➔ Doors: Naturally, you must install soundproofing in each door to reduce noise levels in your car.
➔ Floor: Don’t overlook the floors in your car, either! It’s the closest section to the ground where most road noise originates.
➔ Wheel wells: Last but not least, your wheel wells also require soundproofing. Installing soundproofing materials here will reduce noise from the road, your wheels, and your suspension system.

Regardless of your material, you must install them in all the areas described above. There are plenty of ways noise can enter your vehicle; covering these parts of your car will stop as much of them as possible.

Does Sound Deadening Work In Cars?

Yes, sound deadening is highly effective in cars to eliminate most of the noise you hear.

It’s not surprising that some people still have doubts about the effectiveness of automotive sound-deadening products. That’s because soundproofing requires a significant investment upfront, especially if you want to purchase high-quality materials that give you the results you expect.

Of course, the effectiveness will depend on a few different factors. They include the following:


The effectiveness of any soundproofing solution depends on your car’s primary seals to be in good condition. For example, you’ll still hear noise in your car if your door seals are worn out or damaged.


Another critical factor is the coverage of the soundproofing materials you installed. As you saw in the previous section, several parts of your car must be sealed with soundproofing materials to be effective.

Leaving even one or two of those panels without soundproofing can undermine your entire effort, letting noise continue to bother you inside the vehicle.


Quality is another crucial factor to consider. You’ll find plenty of cheaper soundproofing products that aren’t as effective simply because they use lower-quality materials.

Proper Installation

Of course, the quality of your sound-deadening product won’t matter if they aren’t installed correctly.

So, if you soundproof the vehicle as a DIY job, follow the manufacturer’s instructions carefully. Online video guides are helpful, but you should always err on whatever the manufacturer tells you when installing their product.

Meanwhile, before hiring a professional, it would be worth checking their reviews and reputation to ensure they do a proper job.

Vehicle Condition

Last but not least, your vehicle condition also plays an essential role in the effectiveness of sound deadening. If it has structural or mechanical issues, you’ll still hear noise in a well-soundproofed car.

What Is The Best Material To Soundproof A Car?

Now that you know all about soundproofing your car, here comes the fun (but challenging!) part: choosing the best material to soundproof your vehicle.

While there are plenty of good choices on the market, it’s always best to go with a proven product from which other customers have already benefited. That way, you won’t have to worry about going through the trial-and-error process yourself.
