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