Sound Absorbers - Sound Insulation
(9 products)
Airborne sound attenuation (airborne sound absorption) is achieved by converting part of the kinetic energy of air molecules into heat. This occurs through friction at the interfaces of fibrous or open-cell foam materials that sound waves can penetrate. Absorption is highly frequency-dependent. As a general rule, the lower the frequencies to be attenuated, the thicker the absorption material must be.
