This paper describes about simultaneous generation of multiple 3D sound spots by using large-scale panel loudspeaker array. The large-scale panel loudspeaker array is developed to make three-dimensional multiple sound-spots. We confirm the large-scale 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 3D sound spots from sound pressure distribution measurement result.
