An acoustic board is a board made from sound absorbing materials, designed to provide sound insulation. [3] [4] Between two outer walls sound absorbing material is inserted and the wall is porous. Thus, when sound passes through an acoustic board, the intensity of sound is decreased. The loss of sound energy is balanced by producing heat energy.
A close-up image of acoustic foam. Acoustic foam is an open celled foam used for acoustic treatment. It attenuates airborne 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]
An example of a material in which absorption can observed: sound absorbing foam, also known as acoustic foam.. In acoustics, absorption refers to the process by which a material, structure, or object takes in sound energy when sound waves are encountered, as opposed to reflecting the energy.

A pair of headphones being tested inside an anechoic chamber for soundproofing. Soundproofing is any means of impeding sound propagation.There are several methods employed including increasing the distance between the source and receiver, decoupling, using noise barriers to reflect or absorb the energy of the sound waves, using damping structures such as sound baffles for absorption, or using ...
