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 ...

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

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 ...

the first three of which discuss applications of well-known echo-reduction methods: cancellation, shaping, and absorption. While the specific methods and materials used to achieve this suppression in ...
