Abstract

Angle measurements using traditional auditory analyse with dual-microphones have limited accuracy when the two microphones are close together and the sound sources are moving. This paper presents a method for multiple moving sound source localization with two closely spaced microphones. The method uses an improved gammatone filter bank for the time-frequency analysis of the mixed sound samples, extracts the zero-crossing time difference (ZCTD) that reflects the sound source location feature information and finally statistically analyzes the ZCTD with a Gaussian function to localize the sound source. Tests show that this method gives accurate angle estimates for various kinds of sound sources with various moving speeds along various trajection.

Key words
