Abstract

A method is described to estimate, using many sensors (microphones) both the position and the waveform of individual sound sources by decreasing the effects of other sound sources and reflection from walls and/or ceilings. Some experiments using two sound sources and 16 sensors have been carried out in a room with a reverberation time of 0.5 s, and it is found that the waveform of the specified sound source could be estimated by decreasing the effect of other sound sources by about 20 dB
