Acoustic foam is an open celled foam used for acoustic treatment. It attenuates airbone sound waves, reducing their amplitude, for the purposes of noise reduction or noise control.[1] The energy is dissipated as heat.[2] Acoustic foam can be made in several different colors, sizes and thickness.[3]
Acoustic foam can be attached to walls, ceilings, doors, and other features of a room to control noise levels, vibration, and echoes.[4]
Many acoustic foam products are treated with dyes and/or fire retardants.[5]
