Anechoic chambers are generally used for testing microphones and loudspeakers or other sound-producing devices when the absence of reflection is desirable.

An anechoic chamber is essentially an experimental room lined with RF-absorbent material and contains an antenna positioner and controller that allows for a variety of empirical measurements of ...

Inside the anechoic chamber at Orfield Laboratories, it is so silent you can hear your own blood flowing and bones moving.

A room is said to be acoustically 'dead' when it contains a great deal of sound absorbing material, such that there is little or no REVERBERATION, and strong ATTENUATION of high frequencies. The ...
