ABSTRACT:
An acoustical sound system that triangulates the position of an unknown external sound source by computer analysis. The external sound intensity is measured in three fixed sound sensors. The computer inputs the sound intensities and by the inverse square law of intensity vs distance calculates the coordinates of the external sound source. In addition, once the source's position is known, the computer points a paraboloid microphone and speaker combined, towards the direction of the sound source. This allows a more localized bidirectional link between the source and other electronic connection source.
