摘要
A device is configured for identifying a direction of a sound. The device includes a controller comprising circuitry. The circuitry is configured to receive a first output from a first input device and a second output from a second input device. The circuitry is also configured to add a delay to the second output. The circuitry is also configured to compare the first output to the delayed second output in a plurality of directions to form a comparison. The circuitry is also configured to identify a number of null directions of the plurality of directions where a set of nulls exists based on the comparison.
