A system and method is provided for determining the three dimensional location of an acoustic event using a system of five or more sound sensing elements. The sensing elements are positioned at substantially the same elevation and in spatially distributed locations with respect to the acoustic event. The sensing elements generate notification signals indicating occurrence of the acoustic event. A central processor receives the notification signals, associates the locations of each of the sensing elements with the time at which each sensing element sensed the sound, determines the speed of sound for the medium, and calculates a three dimensional location for the acoustic event using a linear error minimization algorithm. A system of six or more sensing elements enables the processor further to discriminate between near simultaneous acoustic events.

A simulation system for generating movie “scenes” that show interactions between simulated entities that populate a synthetic environment used to support training exercises and equipment. The simulation system includes a simulation engine that produces simulated entity state and event data; a visualization suite that allows an editor to display 2-D and 3-D views of the synthetic battlespace and to hear the battlefield and communications sounds associated with an interaction; a digital data logger that records simulation entity state and event data; an editing processor that provides the functionality required to identify, filter, specify, and organize the “scenes” that make up an interaction of interest; a “scene” generator that converts the entity state and event data for the set of scenes that make up an interaction into a digital movie file; and a repository for storage of complete movies and copying of movies to removable media.
