Simultaneous generation of multiple three-dimensional sound spot by using 512 ch panel loudspeaker array

This paper describes about simultaneous generation of multiple three-dimensional sound spots by using 512 ch panel loudspeaker array. The 512 ch panel loudspeaker array is developed to make three-dimensional multiple sound spots. We confirm the 512 ch panel loudspeaker array can generate four-place simultaneous formation of the three-dimensional sound spot. From this result, voice communication of information to many people is possible. We consider multiple three-dimensional sound spots from measurement result of sound pressure distribution.
