It is typically open-celled. It attenuates airborne sound waves by increasing air resistance, thus reducing the amplitude of the waves. The energy is dissipated as heat.
Many acoustic foam products are treated with dyes and/or fire retardants.
Acoustic foam is often cut into the form of wedges to facilitate the breaking down of the sound waves.
