The Bizarre Forms of Anechoic Foam

Although they may look very odd, anechoic foam wedges are some of the most effective soundproofing materials on the market today. They are not utilized in private residences or public spaces such as theatres, churches or concert halls because of their striking appearance. Also, when used properly to get the full effect, anechoic foam wedges will take up every inch of space on all the walls and ceiling, and sometimes even the floor. Where these fascinating foam pieces are utilized is within an anechoic chamber.

Most often utilized for testing equipment or recording sensitive sounds, an anechoic chamber is a most fascinating room to be within. Because of the shape and pattern of the foam wedges, which are usually set up in alternating wedge patterns to better inhibit sound waves in the room, anechoic chambers tend to look like something out of a science fiction novel. In fact, once within and with the door closed behind you, there will be zero echo, so that any noise made will be the pure and unaffected noise itself and itself alone. That is why it is used for testing machinery that may be too loud in an unprotected space and for recording, which sounds best when no echo is involved at all.

Other elements of the anechoic chamber besides the anechoic foam wedges include very sturdy walls, usually brick, so that no noise from outside the room can penetrate within. The size of the room varies depending on what it is being used for, but realistically, any room with four walls can be made into an anechoic chamber. Also, at times the floor is left bare if the equipment being tested needs to be tested against concrete to resemble the natural habitat it will operate within. So although anechoic foam may look bizarre, as do the anechoic chambers they are utilized within, the space is made to be 100% sound friendly, which is a very rare and wonderful thing indeed.
