SYSTEMS AND METHODS FOR REDUCING UNWANTED SOUNDS IN SIGNALS RECEIVED FROM AN ARRANGEMENT OF MICROPHONES

摘要

A system and method for reducing unwanted sounds in signals received from an arrangement of microphones including: sensing sound sources distributed around a specified target direction by way of an arrangement of microphones to produce left and right microphone output signals; determining the power of the left and right microphone signals; determining the minimum of the two microphone power measures; and, attenuating the signals based on a comparison of the left and right microphone power measures with the minimum power measure.
