Theory and Experiment of Dual Sound Source Localization with Five Proximate Microphones

Abstract

This paper describes a new method for the sound source localization, where dual sound sources simultaneously exist. While conventional array processing methods require the frequency decomposition as pre-processing, our method estimates the directions of sound sources with higher temporal resolution, directly from the original signal and its spatio-temporal derivatives. We show an algorithm for dual sound source localization and a fabrication of the microphone array system.
