Zusammenfassung:	The present invention relates to a sound source measurement apparatus capable of the precision of sound source position estimation by minimizing a time synchronization error of the sound source measurement apparatus at a distance on the sea. The sound source measurement apparatus according to the embodiment of the present invention comprises: a sound detector measuring a sound signal; an oscillator generating and outputting an external clock; and a microprocessor receiving the sound signal measured by the sound detector and calculating a time of capturing the sound signal based on the external clock. 본 발명의 실시예에 따른 음향센서장치는, 음향 신호를 측정하는 청음기; 외부 클럭을 생성하여 출력하는 오실레이터; 및 상기 청음기로부터 측정된 음향 신호를 수신하고 상기 외부 클럭을 기준으로 상기 음향 신호의 포착 시점을 계산하는 마이크로프로세서;를 포함하는 음향센서장치를 제공할 수 있다.
