| Abstract(in English) | In actual room environments, it is easy to assume that the sound source signal arrives with any spatial propagation spread. A method based on the multiplication of the outputs of multiple weighted sum circuits is effective for suppressing a far located sound signal because it can form suppression section though allows a constant gain in the direction of the source. However, the propagation spread depends on the recording environment, and thus a degree of spread is unknown in advance. In this paper, we investigate the effect of the width of the suppression interval on the performance of source separation. |
