    Beskrivelse

    This 33 m2 anechoic room is covered with sound absorbing wedges so that reflections are avoided down to approximately 200 Hz. Many acoustical measurements necessitate the use of anechoic surroundings, e.g. measurements of loudspeakers and microphones, however, this anechoic room is specifically designed for human exposures.

    The room is a double-box construction, and the inner box is placed on a rubber suspension in order to insulate the room against external noise and vibrations. Even when the air-conditioning is on, no audible background noise appears. The wedges inside are made of a foam material. A hoist is placed in the ceiling on which various equipment can be mounted and set in position.
