A sound spot which is a spot-like small area of high sound pressure level can be generated adding the delay of an appropriate amount to each output soud from many speakers. The columnar sound spot can be generated with two orthogonality axes speaker array (64 channel) and the spheroidal sound spot can be generated with three orthogonality axes speaker array (96 channel). The control of these two kinds of speaker arrays, 160 channel speaker array simultaneously, is achieved by plural computers synchronization. This paper reports on the generation of two kinds of sound spots simultaneously with 160 channel speaker array.
