Patent ID: 8767975

Claim:
A method of distinguishing sound sources, comprising the steps of: transforming data, collected by a plurality of transducers which each react to a characteristic of an acoustic wave, into a plurality of signals, one for each respective transducer, the transducers being separated by a distance of less than about 70 mm or greater than about 90 mm, the plurality of transducers having a location; separating each of the plurality of signals into a corresponding plurality of frequency bands; for each frequency, comparing a magnitude difference of corresponding frequency bands of the plurality of signals to a predetermined first magnitude difference threshold value, the magnitude difference threshold value associated with a predetermined distance from the location of the plurality of the transducers; and causing, for a first signal of the plurality of signals, a relative gain change for a first set of frequency bands relative to a second set of frequency bands of the corresponding frequency bands of the first signal, the first set of frequency bands including frequency bands where the magnitude difference falls on one side of the magnitude difference threshold value, the second set of frequency bands including frequency bands where the magnitude difference falls on the other side of its the magnitude difference threshold value, such that the sound sources are discriminated from each other based on their distance from the transducers.
