Abstract
399,554. Reproducing music. JONES, W. B., 38, South Dearborn Street, Chicago, U.S.A. April 8, 1932, No. 10102. [Class 40 (iv).] To produce a binaural effect, musical sounds are transmitted from a single source to a listener by two channels one of which delays the high frequencies and the other the low frequencies, the sounds emitted from 'the two channels being transmitted to reach the left and right ears respectively of a listener so that a directional effect is simulated. As shown in Fig. 1, sounds from a source 10 are communicated to a listener A over channels 11, 12 and ear pieces 15, 16. The channel 12 contains a network 14 which delays the lower frequencies whilst channel 11 contains a network 13 delaying the higher frequencies, the joint effect being that lower notes appear to come from the left, higher notes from the right and medium frequencies from intermediate positions. Fig. 4 shows an arrangement wherein two loudspeakers 28, 29 reproduce the sounds which are heard by a listener at 27. The loud-speakers 28, 29 may be designed to delay the high and low frequencies respectively in which case one or both the networks 13, 14 may be dispensed with.
