The present invention relates to a sound source recognition method and a device thereof. According to the sound source recognition method of the present invention, an acoustic signal is detected from four acoustic sensors arranged in a rectangular shape when viewed in a horizontal direction, and the acoustic arrival time is measured. Six interaural time differences (ITDs) are generated based on a difference in the acoustic arrival time between each acoustic sensor, and a location of a sound source is estimated based on the six ITDs. In addition, by using a summed signal from the four acoustic sensors, a feature of the sound source is extracted and classified so as to recognize the type of the sound source.

    본 발명은 음원 인식 방법 및 장치에 관한 것이다. 본 발명의 음원 인식 방법에 따르면 수평 방향으로 보았을 때 직사각형의 형상으로 배열된 4개의 음향센서로부터 음향신호를 검출하고, 음향 도착시간을 측정하고, 각 음향센서들 간의 음향 도착시간 차이에 기초하여 6개의 ITD(interaural time difference)를 생성하며, 상기 6개의 ITD에 기초하여 음원의 위치를 추정한다. 아울러, 4개의 음향센서로부터의 합산 신호를 이용하여 음원의 특징을 추출하고 분류하여 음원의 종류를 인식한다.
