Abstract

This study is about a sound source direction detection system and method using intelligent source collection and analysis. The sound source direction detecting apparatus according to the present invention is equipped with four microphone sensors and calculates a time difference using TDOA (Time Delay of Arrival) technique for a plurality of acoustic signals generated from a sound source, And a sound source detection and analysis algorithm for estimating the direction of the sound source.
