Abstract

Abstract: Aiming at the lack of ability to resist noise and reverberation and the location estimation low accuracy for the sound source localization method based on microphone array in the indoor sound environments, a sound source localization algorithm based on adaptive multichannel double L-shaped microphone array was proposed. In this proposed algorithm, normalized multichannel frequency-domain least mean square algorithm was used to estimate the impulse responses of different array elements and acquire the time delay under condition of the single source and multiple reverberation model, the spectrum energy was modified by penalty function to improve the ability to suppress noise and avoid channel estimation deterioration, and the method on limited length of the filter was employed for improving the ability to suppress reverberation, as well as double L-shaped microphone array structure was used to improve the localization accuracy in the indoor sound environments. The simulation results show that the proposed algorithm has higher performance of sound source localization in indoor environment and meets the actual demand.
