How Feltmetal® Acoustic Media Attenuates Sounds. When a sound wave is reflected from a hard surface of a silencer, constructive and destructive interference may occur, resulting in a series of maxima and minima in wave amplitude. If a porous material is placed across the wave pattern, the movement of air molecules through the material is converted to heat, resulting in a reduction in sound intensity. This reduction is highest if the material is placed at a location where the air molecule... (read more) -
