Acoustic foam is an open celled foam used for acoustic treatment. It attenuates airport creasing air resistance, thus reducing the amplitude of the waves. The energy is dissipated as heat. Acoustic foam can be made in several different colors, sizes and thickness.
Acoustic foam is a lightweight material made from polyurethane foam either polyether or polyester, and also extruded melamine foam. It is usually cut into tiles – often with pyramid or wedge shapes – which are suited to placing on the walls of a recording studio or a similar type of environment to act as a sound absorber, thus enhancing the sound quality within a room.
Acoustic foam reduces or eliminates echoes and background noises by controlling the reverberation that sound can make by bouncing off walls. This type of sound absorption is different from soundproofing, which is typically used to keep sound from escaping or entering a room. Therefore, acoustic foam is installed in large rooms like churches, synagogues, concert halls. These rooms have large, flat space and noise will certainly bounce around in the room. These sound absorbers are used to improve the acoustics of the room, which thereby reduces noise in the room.
