ABSTRACT:
In a method for locating sound sources, signals from three aligned sensors are processed by correlating the signals of the central sensor with those of the outer sensors and then by processing the correlation signals so as to maximize the sum of these signals, thus making it possible to identify the position of the noise sources more efficiently.
