Optimal source distribution for binaural synthesis over loudspeakers

摘要

When binaural sound signals are presented with loudspeakers, the system inversion involved gives rise to number of problems such as loss of dynamic range, deterioration of control performance by small errors and room reflections. These problems for such systems are investigated and this has resulted in the proposal of a system, the Optimal Source Distribution ("OSD") system, which overcomes these problems by means of variable transducer span. As for the elevation location of the control transducers, the transducers in the frontal plane above the listener's head are proved to be advantageous against the transmission of false dynamic information.
