Abstract

Sound source localization can be achieved via the beamforming technique by using array of microphones. The locations of dominant sources can be determined by beamforming method but the nature of the source signals cannot be characterized. To overcome this difficulty, an approach which can achieve sound sources localization, identification and characterisation by post processing on the output of the beamforming technique is proposed. The error signals can be eliminated by a sequence of steps such that the feature of the main sources can be extracted from the mixed measurement signals accurately. The proposed approach gives promising results of the sound source localization and characterization in free field condition in both simulation and experimental validations.
