Acoustic foam

A close-up image of acoustic foam.

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]
