Sound Dampening: The Details

EVERY VEHICLE CAN BENEFIT FROM SOUND DAMPENING. HERE’S A QUICK READ ON THE DIFFERENT PRODUCTS THAT MAKE THEN PROCESS BENEFICIAL FOR KEEPING SOUND IN OUR KEEPING NOISE OUT.

At AiAutoWorks we do restoration and protection work on every style and class of vehicle on the market today, and the classics that are being built in a hobbyist’s garage. New or old, expensive or inexpensive, there are a few services that add value to most vehicles, and sound dampening is one of them. As we point out on our website, there are two main reasons for using sound dampening. Either you’re trying to keep the noise out our you’re trying to keep it in. Here’s the basics on how that works, beginning with the materials we use.

SOUND DAMPERS

Dampers are by far the most common type of material used in sound dampening. They are most commonly used throughout a vehicle to control structural related noises. They can also be used in conjunction with a composite to reduce road, engine, and exhaust noise.

SOUND DAMPENING: ABSORBERS

These products literally absorb airborne sound waves. Absorbers are most commonly used on floors and firewalls to reduce road/engine/exhaust noise. The sound waves have to move through the absorber, so the open/closed cell foam will slow its progress, reducing the overall sound level in the process.

COMPOSITE SOUND DAMPENERS

The best results are achieved by using more than one of sound deadening options, so a composite is quite simply a combination of two of the above types into a single easy to install product. Whether you’re looking to take your sound system to the next level or make your classic car quieter on the inside, composite sound dampening is the best option.

We use a variety of different products for different purposes, but one of our go-to products is HushMat. It’s a must have for any classic car restoration, and they were pioneers in the car stereo market. Here’s a quick video about HushMat and how it works:
