How Sound Deadening Materials Enhance Your Car Audio

For car audio enthusiasts and everyday drivers alike, the quest for the perfect sound experience in a vehicle is often a top priority. But achieving crystal-clear audio quality is not solely about investing in high-end speakers or amplifiers; it's equally about understanding and managing the acoustic environment within your car. In this realm, sound deadening materials play a pivotal role, serving as an unsung hero in the journey towards audio excellence in vehicles.

The Science of Sound in Vehicles

The science of sound in a vehicle is complex and intriguing. A car's interior, characterized by its small and enclosed space, poses unique challenges for sound quality. Sound waves generated by your audio system can reflect off hard surfaces like windows, dashboards, and doors, leading to echoes, reverberations, and ultimately, sound distortions. Additionally, external noises - from the engine, road, wind, and even other vehicles - can infiltrate the cabin, further degrading the listening experience. This is where sound deadening materials come into play.

Basics of Sound Deadening Materials

Sound deadening materials, often composed of dense, vibration-absorbent substances like rubber, foam, or specialized composites, are engineered to address these acoustic challenges. They function by absorbing sound waves, thereby reducing the extent to which these waves bounce around the interior of your car. Moreover, by dampening vibrations, these materials minimize the resonance of the car's panels and components, which can significantly contribute to noise within the cabin.

Impact of Sound Deadening on Car Audio

The impact of sound deadening on car audio quality is both profound and multifaceted:

Improved Soundstage Precision

Enhanced Instrument Separation: Sound deadening materials contribute to a more accurate and immersive soundstage by reducing unwanted reflections and echoes. This allows listeners to discern individual instruments and voices more clearly, creating a concert-like experience.

Precise Spatial Imaging: With reduced cabin resonance, the audio system can more accurately reproduce the spatial characteristics of recorded music. This means that when listening to a well-recorded track, you can pinpoint the location of instruments and vocals with precision.

Reduction in Distortion and Harmonic Overtones

Cleaner Audio Reproduction: Sound deadening minimizes the distortion caused by vibrations in the vehicle's structure. As a result, audio reproduction becomes cleaner, with less coloration or alteration of the original sound.

Reduction of Harmonic Overtones: Vibrations and resonances within the car's interior can introduce unwanted harmonic overtones to the audio signal. Sound deadening helps in suppressing these overtones, ensuring that the music you hear is faithful to the artist's intent.

Enhanced Low-Frequency Response

Tighter and More Defined Bass: The impact of sound deadening on bass response is particularly notable. By reducing panel vibrations and rattles, low-frequency sounds become tighter and more defined, enhancing the depth and punch of bass notes.

Reduced Boominess: In untreated vehicles, booming or muddiness in the bass is common due to resonance. Sound deadening materials effectively combat this issue, resulting in a more controlled and enjoyable bass experience.

Increased Dynamic Range

Greater Dynamic Contrast: A wide dynamic range is crucial for conveying the full emotional impact of music. Sound deadening allows for a greater dynamic contrast between soft and loud passages, creating a more engaging listening experience.

Less Need for Volume Compensation: With reduced external noise intrusion, you can enjoy music at lower volumes while still hearing all the details. This not only enhances the audio quality but also reduces listener fatigue during long drives.

Immersive In-Car Entertainment

Optimal Environment for Multimedia: Sound deadening materials create an optimal environment for in-car entertainment. Whether you're enjoying music, podcasts, or watching movies, the cabin's acoustic improvements enhance the overall multimedia experience.

Clear Hands-Free Calls: Improved cabin acoustics mean clearer hands-free phone calls. Sound deadening reduces background noise, allowing for better communication and reducing the need to raise your voice during calls.

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.
