ABSTRACT:
A binaural four-channel stereophony comprises at least two dummy heads each provided with microphones at the ears of the dummy to pick up signals from various sound sources or groups of sound sources. The binaural signals representing each sound source or a group of sound sources are coupled to an acoustic crosstalk cancellation circuit and eventually applied to two front or two rear loudspeakers. Each sound source or group of sound sources is localized between adjacent ones of the four speakers to simulate the binaural effect produced in a closed-circuit type binaural sound reproducing system.
