Abstract: A sound source localization method based on microphone array is presented for acoustic source localization problem in noisy and reverberant environments.In the framework of particle filtering，the speech signal is served as the observation information，and likelihood function is constructed by the output power of beamformer.The results of simulation data and real data show that the proposed method can reliably confirm the acoustic source’s position even in moderately reverberant rooms.Even in the environment of low SNR and strong reverberation，the adopted method can also give effectual localization.
