| Abstract(in English) | This paper describes a process of estimating the sound source information based on blind source separation when the number of sound sources is large. In this study, a small dodecahedral microphone array device was developed and source separation system with this microphone array was proposed. We propose a method of solving permutation problem, which caused by frequency domain independent component analysis. This method uses an acoustic pressure distribution observed in surface of the dodecahedral microphone array. Experimental result showed that the performance of this method was equal to ideal result when two sources were existed in near field. |
