Abstract
A system and method for detecting, identifying, and fixing the location of the source of an acoustic event. The inventive system includes: a plurality of sensors dispersed at somewhat regular intervals throughout a monitored area; a communication network adapted to deliver information from the sensors to a host processor; and a process within the host processor for determining, from the absolute times of arrival of an event at two or more sensors, a position of the source of the event. Acoustic events are detected and analyzed at each sensor so that the sensor transmits over the network: an identifier for the sensor; an identifier for the type of event; and a precise absolute time of arrival of the event at the sensor. In a preferred embodiment, the system also identifies the type of weapon firing a gunshot.

15. A method of processing communications related to weapon fire identification, the method comprising:
-
accessing a wireless network, wherein at least three sensors across an area to be monitored are networked, and wherein each of the at least three sensors is configured to detect an acoustic event; obtaining sensor location data for each of the at least three sensors; performing time of arrival processing of the acoustic event at each of the at least three sensors; determining an approximate location of a source of the acoustic event as a function of arrival time and sensor location data; and transmitting information including the approximate location or data related to the approximate location via a network.
