Abstract

A method for determining a physical location of a source is provided. The method includes receiving an acoustic signal from a source placed within an acoustic monitoring area. The method also includes processing a received acoustic signal. The processing is configured to use data from at least two sensors. Also included is identifying an approximate localized point in the acoustic monitoring area. The approximate localized point defines a physical location of the source. The method further includes reporting the physical location of the source over a network.
