| Abstract | (in Japanese) | (See Japanese page) |
| (in English) | We propose the sound spot reproduction method that is recomposing sub-signals decomposed input signal on the target space. 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. However, there is the problem that could be hear the speech contents in the suppression area because MPCM is only a little deteriorate speech quality. In this study, we propose the method that is able to listen the speech contents in a limited spot. This method is that reproducing three sub-signals decomposed input signal. We used MPCM with the playing method. Moreover, we study on the playing method that using virtual sound source by wave field synthesis. As the result of computer simulation, we confirmed listening area is smaller than regular area reproduction using MPCM. Moreover, we confirmed suppressing sound pressure of sub-signals in the outside of target area even though using virtual sound source. | |
