Abstract: In order to solve the problem that the traditional methods could not accurately measure the localization of multiple sound sources in far field, this paper presented a new multiple sound sources localization method, which could be used both in the near field and the far field. Two L-shape microphone arrays were used in the proposed method. In each array, signal's DOA was obtained by jointly estimating the DOA and frequencies of signals. Finally, locations of multiple sound sources could be estimated based on DOA's pair of two L-shape microphone arrays. The simulation examples indicated that locations of multiple sound sources could be accurately measured by the proposed method. By adjusting the distance between two L-shape microphone arrays, the standard deviation below 5% could be obtained, which showed the sound localization accuracy.
