Abstract (en)
[origin: EP0377144A2] A solution is specified how the reproduction device for sound events can be designed in such a manner that the diffuse sound at the location of listening produces a uniform frequency-independent loudness. This is achieved by the fact that the audio-frequency signal supplied to the sound transducer system is distorted in such a manner that the diffuse sound exhibits at the location of listening the same loudness characteristic which would be exhibited by a sound transducer operated with undistorted audio-frequency signal in an anechoic room. <IMAGE>
