An anechoic chamber is a shielded room that has radio-wave absorbing material applied to the walls, ceiling, and floor. Chambers may be table top sized enclosures, but are normally room sized enclosures where engineers can walk in and work. The absorbers on the inside surfaces are often pyramidal shape, and give the room an unique “science fiction”

anechoic chamber architecture. In this kind of space, no one can hear you scream. Anechoic chambers use spiked walls to eliminate echoes, the end result might literally sound dull but the visual effect can be stunning, such as at the enormous anechoic hangar.
