AUDITORY DISTANCE PERCEPTION IN DIFFERENT ROOMS

A series of listening experiments was carried out to investigate how a uditory distance is perceived in different rooms-an anechoic room, an IEC listening room, and a classroom. Loudspeakers playing back a voice signal were placed in the rooms. The results show that in normal room s the sound is perceived at about the same distance as the physical di stance, regardless of the playback level. In the anechoic room there i s no correspondence between physical and perceived distance.
