Abstract

A system and method for detecting the exact location of an acoustic event, the system comprising a plurality of variably spaced sensors, wherein each sensor comprises an omnidirectional microphone for detecting the acoustic event; a global positioning system (GPS); and a transmitter receiver for transmitting (i) the time that the acoustic event arrived at a particular sensor and (ii) the location of the particular sensor at the time the acoustic event arrived at the particular sensor; and a central processor radio-linked to the plurality of variably spaced sensors comprising a software program comprising at least one algorithm for determining the location of the acoustic event.

Claims

1. A system for detecting the exact location of an acoustic event, the system comprising:

a plurality of variably spaced sensors, wherein each sensor comprises;

an omnidirectional microphone for detecting the acoustic event;

a global positioning system (GPS); and

a transmitter receiver for transmitting (i) the time that the acoustic event arrived at a particular sensor and (ii) the location of the particular sensor at the time the acoustic event arrived at the particular sensor; and

a central processor radio-linked to the plurality of variably spaced sensors comprising a software program comprising at least one algorithm for determining the location of the acoustic event.

2. A method for detecting the exact location of an acoustic event, the method comprising:

providing a system comprising;

a plurality of variably spaced sensors, wherein each sensor comprises;

an omnidirectional microphone for detecting the acoustic event;

a global positioning system (GPS); and

a transmitter receiver for transmitting (i) the time that the acoustic event arrived at a particular sensor and (ii) the location of the particular sensor at the time the acoustic event arrived at the particular sensor; and

a central processor radio-linked to the plurality of variably spaced sensors comprising a software program comprising at least one algorithm for determining the location of the acoustic event;

transmitting (i) the time the acoustic event arrived at the particular sensor and (ii) the location of the particular sensor at the time the acoustic event arrived at the particular sensor to the central processor;

applying a first algorithm to the time and location of the particular sensor to generate an approximate location of the acoustic event; and

applying a second algorithm to the time and location of the particular sensor to detect the exact location of the acoustic event.
