1. A system for determining the three dimensional location of an acoustic event producing sound in a medium, comprising:

  • five or more sensing elements at substantially the same elevation and in spatially distributed predetermined locations with respect to the acoustic event, for sensing sound in the medium and generating notification signals upon sensing sound from the acoustic event;

    a processor;

    a communication interface between the five or more sensing elements and the processor for communicating the notification signals from the five or more sensing elements to the processor; and

    said processor is configured to determine the speed of sound in the medium and to calculate the three dimensional location of the acoustic event as a function of the times of generation of the notification signals and the respective predetermined locations of the five or more sensing elements, by using a linear minimization algorithm.
