What Is Sound Dampening & Deadening?

Sound dampening removes vibrational energy by acting as a shock absorber, thus quieting the sound that something transmits. Sound-dampening materials work to reduce rattling vibrations in your car, at home or at work. You can put an end to the tedious noise pollution caused by appliances and city streets with sound-deadening and dampening materials that are specially made to absorb and dissipate unwanted sound clutter.


Our sound-deadening materials come in a variety of shapes and sizes. Materials can be easily painted into oddly shaped surfaces, like on generators and pumps, or peeled and stuck into easily accessed spaces like cabinets and car hoods. Sound dampening is a great solution for industrial workers, car enthusiasts, maintenance workers and do-it-yourselfers who are tired of having air conditioning units that rattle and vibrate like a shopping cart with a broken wheel.

What Is the Best Way to Dampen Sound?

The best way to dampen sound is to apply specialized materials that reduce vibrations and absorb and dissipate unwanted noise.

For example, installing sound-dampening material can reduce the noise created by rattling water pipes in your home. It can also prevent steel structures from vibrating on construction sites. For cars, sound-deadening materials can block out road noise. No matter the application, sound-deadening materials absorb energy so that the surface they’re applied to transmits less sound.

I just wanted to let you know that in the end, sealing the air spaces on this door worked just fine and took care of the problem.

I really appreciate you taking so much time to share your expertise with me, and in particular recommending I try the simpler solution before investing in more expensive noise barriers. That is a big credit to you and your business.
