Abstract

817,773. Binaural systems. LYONS, W. Oct. 18, 1957 [Jan. 10, 1957], No. 1002/57. Class 40 (4). Signals from two channels 3 and 4 are mixed at 5 and a desired proportion of the mixed signal is returned to the two channels at 7 and 8, the arrangement being such that direct interaction between the two channels is prevented. The mixed signal is distorted and delayed at 6 in order to simulate the effect of sound waves travelling through bone, to increase the apparent realism of the final reproduction. The input ends of the two channels 3 and 4 may be connected to microphones 1 and 2 as shown or to two gramophone or like pick-up heads, and the output ends may be connected to headphones 9 and 10 as shown or to two recording heads: An amplifier may be included in each channel.
