Abstract
A system for locating a sound source includes at least four emitter/receiver pairs, each emitter/receiver pair of the at least four emitter/receiver pairs including a laser emitter and a receiver external to an enclosed structure. The laser directs a laser beam onto a respective reflector surface location on an outer surface of the structure, the respective reflector surface location being caused to vibrate due to sound waves generated from a sound source at a sound source location within the enclosed structure. The receiver receives vibrational signals from the laser beam on the surface at the respective reflector surface location and converting the vibrational signals to acoustic signals. A processor coupled to the emitter/receiver pairs for utilizing the acoustic signals to determine a time difference of arrival of the sound waves to the respective reflector surface locations to determine the sound source location based on the time difference of arrivals.
