Is Car Sound Deadening Worth It? Exploring the Benefits and Options

When it comes to enhancing the driving experience, car sound deadening is a topic often discussed among automotive enthusiasts and everyday drivers alike. The constant hum of road noise, the roar of the engine, and the various squeaks and rattles that accumulate over time can detract from the joy of driving and even affect vehicle communication and comfort. But is investing in sound deadening really worth it? This blog aims to uncover the true benefits of car sound deadening, explore the different options available, and help you decide if it's the right choice for your vehicle. From improved audio quality to increased resale value, we'll examine how sound deadening can transform your driving experience.

What is Car Sound Deadening?

In this section, we delve into the essence of car sound deadening, explaining not just what it is but also how it functions to enhance the driving experience. Sound deadening refers to the process of adding materials to a car’s interior to absorb and reduce noise generated from both external and internal sources. This can include road noise, engine sounds, and vibrations from the vehicle’s structure itself.

Understanding Sound Deadening Materials

Sound deadening materials are designed to dampen vibrations and absorb sound waves. Common materials used include specialized mats, foam, sprays, and insulation that are applied to the doors, floors, roof, and even the trunk of the vehicle. Each material has its own properties and effectiveness, tailored to different parts of the car for optimal noise reduction.

How Sound Deadening Works in Cars

The effectiveness of sound deadening materials comes from their ability to convert sound energy into a small amount of heat, dissipating it before it can reverberate throughout the car’s interior. By creating a barrier against noise intrusion and absorbing vibrations, these materials significantly reduce the audible clutter that can make driving stressful or less enjoyable.

The Benefits of Car Sound Deadening

Investing in sound deadening for your car goes beyond just muffling unwanted noise. This section highlights the significant advantages that sound deadening can offer, making it a worthwhile consideration for many vehicle owners.

Enhanced Audio Quality

One of the most noticeable benefits of sound deadening is the improvement in audio quality inside the vehicle. By reducing ambient noise, sound systems can perform at their best without the need to increase volume to compete with external sounds. This means clearer, crisper audio playback, whether you're listening to music, a podcast, or taking a phone call. It's particularly appreciated by audiophiles who value the purity of sound.

Increased Comfort and Privacy

Sound deadening also contributes significantly to the overall comfort and privacy within the vehicle. With reduced road noise, conversations can be held at a lower volume, and less noise from the outside world intrudes, creating a quieter, more secluded environment. This privacy is particularly valued in urban settings or during long road trips where external noise can be a constant annoyance.

Improved Vehicle Value and Longevity

Adding high-quality sound deadening can also enhance the resale value of your car. A quieter cabin is often associated with luxury and can be a selling point for potential buyers. Additionally, sound deadening materials help protect against rust and wear by providing an extra layer of insulation from moisture and debris, potentially extending the lifespan of the vehicle’s interior components.

Options for Car Sound Deadening

Choosing the right sound deadening solution can vary greatly depending on your budget, vehicle type, and desired outcome. This section covers the spectrum of choices, from DIY projects to professional services, along with a look at the various materials that can be used.

DIY vs. Professional Installation

For those who enjoy hands-on projects, DIY installation of sound deadening materials can be a rewarding endeavor. It allows for customization and can be cost-effective, particularly for smaller areas or specific sections of the vehicle. However, DIY installations require a certain level of skill and patience, and mistakes can be costly or ineffective.

On the other hand, professional installation guarantees a more comprehensive and assured result. Professionals have access to high-quality materials and tools, and their experience ensures that the sound deadening is applied correctly and efficiently. This option is ideal for those who prefer a hassle-free process or who want to ensure that the entire vehicle is treated comprehensively.

Types of Sound Deadening Materials

There are several types of sound deadening materials available, each with its own advantages:

  • Damping mats: Typically made of butyl and aluminum, these are used to cover large flat metal surfaces like doors and floors.
  • Foams: These can be sprayed or laid in sheets to fill cavities and cover complex surfaces.
  • Insulation liners: Often used under carpets and in the trunk, these materials provide both sound dampening and thermal insulation.
  • Spray coatings: Ideal for irregular surfaces and hard-to-reach areas, these provide a layer of soundproofing across various materials and shapes.

Considerations for Choosing the Right Option

When deciding on a sound deadening solution, consider factors like the specific areas of your car that need treatment, your budget, and how long you intend to keep your vehicle. Also, think about the climatic conditions your car is exposed to, as some materials may perform better in certain environments than others.


Car sound deadening is an investment in both the comfort and performance of your vehicle, offering a quieter cabin environment that enhances the overall driving experience. While the cost and method can vary—ranging from DIY projects to professional installations—the benefits of reduced noise, increased privacy, and enhanced audio quality are clear. Additionally, the potential to improve vehicle resale value and longevity makes sound deadening a worthwhile consideration for any car owner looking to elevate their ride. Whether you’re an audiophile desiring pristine sound or a daily commuter seeking solace from road noise, sound deadening provides a customizable solution to meet diverse needs.

Step 1

To install the material you need be working on the metal surface of the car, remove upholstery. If you have never done this, we suggest searching it up on YouTube. Once the upholstery is removed, make sure there is no debris, waxy oils or rust by cleaning the surface with denatured alcohol.

Step 2

Once surface is clean and ready to go, cut the sound deadening material to the right size so it fits desired area. For small surfaces, we recommend that you measure the dimensions and then cut to fit.

Step 3

With the surface area clean and pieces cut to desired dimensions, peel off the paper and apply material to surface area starting from the top to bottom using the car door holes to help with alignment. We recommend using a hand roller to ensure that there are no air pockets and ensure the adhesiveness.

Sound Deadener Install FAQ: Tips & Tricks

What tools will I need to for a sound deadening project?  
  • Rag & Denatured Alcohol: Apply the alcohol to the rag and use to clean the metal surface areas you will be applying the material to.
  • Gloves: Our product is pretty safe to install without gloves but if you have never installed a sound deadener mat, we recommend using gloves.
  • Hand roller: We highly recommend using a small roller to reach the tighter surface areas of your vehicle. You can find these on Amazon or most online retail shops. There are wooden, rubber and metal rollers, we recommend wooden or rubber, try and stay away from metal as they can tear the material.
  • Utility Knife: The utility blade is to cut the material. Make sure to cut the material on top of a pice of cardboard so that your blade stays sharper longer, if it's a big job, have some extra blades around.
How do you apply sound deadener material? 

We sell our roll on sound deadener product in 2 different formats: custom cut to fit pro kits and an easy to work with rolled up large sheet. If you can measure, cut, peel and stick you can install sound deadener! You can use your hand to apply pressure when positioning the material and then use a roller to make sure it sticks down to metal surface.

After you cut the material and are ready to stick it on, some customers find it easier to peel off a small portion of the release liner and then apply it to metal surface, and then work their way across the sheet, peeling off a small section at a time.

Make sure to always remove the air bubbles with the roller. The second most important thing when it comes to quality of sound deadener is the quality of adhesion to the surface area. You want the material to be stuck down properly to ensure it stays in place.

Where do you apply the sound deadening material?  

The great thing about our sound deadening material is that it can be applied to all types of metal surfaces. All SoundSkins sheets use extremely strong adhesive and they can even be mounted on fiberglass, plastic and even wooden surfaces, but it's not very common to apply to these surfaces since they don't vibrate as much. By covering all metal surfaces such as your doors, roof, trunk and floor you can make a significant difference to unwanted road noise.

Your top priority when applying a car sound deadener is to cover the doors, floor and trunk. If you have extra material then proceed to other metal surfaces you wish to cover for extra sound insulation.

How much surface area should I cover?  

To properly deaden the metal surfaces, we recommend to at least do 25% coverage with our SoundSkins material, this will make a difference in unwanted road noise, but to have a huge impact we recommend covering up 60% of metal surfaces. If you want to get the most used from your sheet, one effective strategy is the CHECKER BOARD APPROACH, using this technique you cut the SoundSkins sheet into small pieces and apply them to the metal surface in a checkered pattern.

It is very common for our customers to do close to 100& coverage to any metal surface because not only are they looking to reduce road noise, they also want to insulate their car from heat or they like the way the material looks on the car's bare metal surface.

How do I make sure the sound deadener sticks well?

SoundSkins products are made with a very strong adhesive and create a extremely strong bond with the metal, it's really hard to NOT make it stick. To ensure the best possible bond, we highly recommend cleaning the metal surface before applying our material and then using a hand roller to firmly attach the SoundSkins deadening mats.

Great adhesion with no air bubbles is the absolute key if you want to get the best performance. Remember that any air pocket with poor adhesion means you will not get the full benefit of the deadener.

How to install car sound deadener: Recap
  1. Remove upholstery and carpet from your vehicle. Proceed to vacuum to get rid of debris and dirt. Clean all greasy spots with denatured alcohol, other solvents or degreasers will leave behind a film that prevents a solid contact surface. Allow metal surface to try.
  2. Cut the SoundSkins sheet to desired size and cut using a sharp utility knife. Use gloves to avoid any cuts.
  3. Peel off the wax paper from the back of material and apply to surface, this can be done by small sections at a time. Use roller to create a strong bond between material and metal surface and to get rid of any air bubbles.
