Abstract (in Japanese) (See Japanese page) 
(in English) We propose the sound reproduction method that reproducing difference speech in multiple zone by using the sound reproduction method in a limited zone. The multi-point control method (MPCM) based on boundary surface control principle (BoSC) was proposed. MPCM is the method that control sound pressure characteristic in each control point based on the numerical calculation of the inverse of the spatial correlation matrix between control points and the positions of the loudspeakers. The sound reproduction to multiple zone is realized by overlapping speech reproduced to each zone. In this paper, we study on the multiple zone reproduction by MPCM using 16ch linear loudspeaker array. We evaluated multiple sound zone reproduction by using MPCM in real environment and computer simulation. We confirmed that decreasing leak sound by setting suppression control points on boundary of suppression zone. Moreover, we study transfer function of MPCM by relative sound pressure level and subjective test in real environment. As these results, we confirmed the method that replacing transfer function of suppression control points with free field transfer function was effective.
