| Abstract(in English) | In this paper, we propose a novel algorithm to localize two independent sound sources simultaneously. The method is an extention of the spatio-temporal gradient method and localizes angles and distances of dual sound sources with high temporal resolution. We l)derive specific partial differential equations, which are satisfied at observation point, when two wave front generated from two point sources are arrived 2)propose the localization algorithm to judge unknown arrangement of sound sources and to estimate its localization parameters, and 3)show experimental results by using five proximate microphone arrayed in cross shape. |
