Soundproofing Plus: The Definition of (and a Misconception About) Noise Dampening Materials

The Definition of (and a Misconception About) Noise Dampening Materials

Noise dampening materials … what are they, really? My old college dictionary tells me that “dampen” is a transitive verb meaning:

(1) to make damp;
(2) to deaden, restrain, or depress; to check or diminish the activity or vigor of;
(3) to soundproof.

We can dismiss number one right away. It never has been nor will it ever be the mission of Audimute to soak our customers—literally or figuratively. Two and three, on the other hand, hold the key to understanding noise dampening materials, and number three also sets forth a misconception that is so common that it made it into the dictionary.

“Restrain” is exactly what noise dampening materials are supposed to do. Audimute sound absorptive sheets, for example, are designed to restrain mid- and high frequencies, preventing echo, reflection, and distortion.

“Soundproof” is not as accurate. Absorptive materials can provide some soundproofing qualities, but they’re primarily intended to clean up sound, not prevent it from escaping. Other materials are tailor-made for soundproofing.

The distinction is subtle but important. So important, in fact, that we put together a video explaining what sound absorption is, what noise dampening materials do, and how they do it. Take a look, and then if you’d like more information on absorption or soundproofing, Audimute is here to help. Call 866-505-MUTE (6883) or visit us for an online chat at
