PROBLEM TO BE SOLVED: To constitute a method of sampling an acoustic source, a method of determining the location of the acoustic source, a method of searching the acoustic source, and a method of intensifying the acoustic signal from the acoustic source, and to improve the accuracy of the acoustic source search. SOLUTION: The present invention includes the sampling of the acoustic source 210, in a plurality of acoustic receivers 205, 315 that differ in locations; the each acoustic receiver imparts a time stamp to an acoustic sample received in the each using a system time (320, 330); the each acoustic receiver transmits the acoustic sample imparted with the time stamp to a central controller (325); and the central controller 525 determines the location of the acoustic source (630), in response to the reception of the acoustic sample imparted with the time stamp, from each of the plurality of acoustic receivers.
