ABSTRACT:
A sound reproducing system for reproducing sounds from two loudspeakers located in front of a listener comprises a difference creating network for causing a ratio of sound pressures applied to left and right ears of the listener and causing a time difference between sound waves thereat by a sound radiated from a sound source located at any point around the listener, and a front and back recognizing network provided in common with both ears for cancelling information which causes the listener to feel that said loudspeakers are located in front of the listener and enabling the listener to localize a sound image at any point, whereby the listener can localize the sound image at any point around the listener while he is listening the sounds radiated from the two loudspeakers located in front of him.
