Car Audio: Sound Deadening Your Vehicle

One of the most important (and usually overlooked) areas where you can actually achieve a great improvement in sound quality with any car audio system is in sound deadening. It is here that you can actually greatly reduce if not eliminate all the areas of your vehicle that hinder sound system performance- right down to improving mid-bass response!

Many of us have simply installed components and have ignored the acoustic limitations of our vehicles, only to find later that we had unwelcome vibrations, road noise or other factors which have taken away from our system’s true capabilities. Auto manufacturers have actually provided some levels of sound deadening for years, but this was never meant to address acoustic limitations. Over the past decade, however, there has been a movement within the car audio industry to actually address this problem and thankfully there are some good options available for the consumer.

I’m going to discuss one such company, Hushmat, mainly because of their extensive amount of experience in the OEM industry and the great quality products they offer. Hushmat got its start within the automotive industry as its Ultra* line of materials has been specified and used by North American Automobile Equipment Manufacturers (OEM’s) for over 19 years! Vehicles produced by General Motors, Ford Motor Co., Daimler Chrysler, Misubishi, Toyota and Honda all specify and use these materials, making Hushmat the best choice for aftermarket applications.

Hushmat applications include floors and spare tire wells, which greatly reduce road noise and vibration.

Hushmat comes in a variety of options that provide solutions for every aspect of vehicle sound deadening. Bulk Kits offer enough material to effectively treat the entire vehicle floor and some side panel areas, while specific kits are also available for inner door skin areas, speaker areas, trunk lid/ floor areas and even license plate areas. All of these areas of the vehicle are sources of noise and vibration, and using Hushmat actually reduces these culprits with excellent results. In fact, using Hushmat also reduces heat by up to 40 percent, making it a great option for firewall applications, too!

Going a step further with MegaBond Foam:

Hushmat’s Silencer Megabond High Frequency Sound Absorbing Foam is yet another great option for reducing the high frequency noise that distorts your mobile entertainment system. This rubber-based foam actually isolates the vehicle interior from road noise, engine noise, exhaust and wind noise passing behind trim panels. Silencer Megabond is available in three (3) thicknesses and is formulated specifically for the rigors of the automotive industry.
