| Abstract(in English) | In this paper, we propose a method for detecting sound source direction using coefficients of adaptive filter. For detecting the sound source direction, we need to defferentiate the direct sound from the refrection sounds. In practical systems, the direct sound is not always smaller than refrection sounds. We proposes a method differentiating those by using the fluctuation of the coefficients of the adaptive filter and then show using computer simuation that the mrthod succesfully works. |
