In the present article we present a new method for multiple sound source localization. The method relies on the phase differences among the corresponding frequency components derived from the signals picked up by a set of three microphones, where the sound sources are assumed to be coplanar with three microphones. In order to cope with echoes, the precedence effect discovered by Wallach is incorporated. As for the multiple sound source localization, the phase differences are measured around the transient portions of the signals and the candidates for the correspondences between the transient portions of the frequency components the signals are extracted. A kind of histogram is used to determine the correct correspondences from the candidates, which results in multiple sound source localization.
