Sound reproducing arrangement for artificial reverberation

A sound-reproducing arrangement for artificial reverberation comprising, a plurality of loudspeakers arranged within an enclosed space, a plurality of microphones and a plurality of amplifiers, means connecting the loudspeakers to associated microphones via the amplifiers to form a plurality of separate mechanical units each of which includes a microphone, an amplifier and a loudspeaker connected in cascade, the loop gain of each of the mechanical units having a value less than one, and wherein the separate mechanical units are arranged in such a way relative to each other that the sound energy which the microphone of one mechanical unit picks up from its own loudspeaker is low relative to the sound energy which is picked up in total by said microphone from the loudspeakers not belonging to said one mechanical unit.
