Abstract(in Japanese) (See Japanese page)
Abstract(in English) Various sounds exist around us. We select the kind and the direction of the sounds that we need in that of unconsciousness, and we are collecting significant information by ourselves. We have developed an estimation method of the direction of arrival of sounds and enhancement method of selected sounds in case of using 2ch receiving like human, based on coincident defection of both channels. Sound components from the same sound source have similarity for amplitude envelopes in time. In this research, we proposed an improvement method of our previous method using the above similarity. Smoothed instantaneous amplitude time series of signals were calculated after our previous method in each frequency band and direction, and sound components which have similar amplitude series were grouped into a single sound.
