NOISE SUPPRESSION BASED ON CORRELATION OF SOUND IN A MICROPHONE ARRAY

摘要

A microphone array includes a left microphone, a right microphone and a processor to receive a right microphone signal from the right microphone and a left microphone signal from the left microphone. The processor determines a timing difference between the left microphone signal and the right microphone signal. The processor determines whether the timing difference is within a time threshold. The processor time shifts one of the left microphone signal and the right microphone signal based on the timing difference. The processor also sums the shifted microphone signal and the other microphone signal to form an output signal.
