Patent ID: 8553904

Claim:
A method of locating a sound source using a computing device, the method comprising: executing, by the computing device, an iterative process, each iteration of the iterative process comprising: subdividing a current space into a plurality of subregions, each subregion having an associated subregion volume; computing a sound source power for each subregion; selecting a subregion of the plurality of subregions having a largest sound source power of the computed sound source powers; determining whether the subregion volume associated with the selected subregion is less than a threshold volume; in response to determining that the associated subregion volume is equal to or exceeds the threshold volume, setting the current space to the subregion having the largest sound source power, and repeating the iterative process; and in response to determining that the associated subregion volume is less than the threshold volume, outputting the subregion having the largest sound source power as a location of the sound source.
