Abstract
System and method for controlling incoming acoustic signals at a portable accessory communication system provides improved management of noise levels. A plurality of acoustic microphone arrays (), formed of pairs of acoustic microphones, and a single vibration microphone () are enabled by pressing a push-to-talk (PTT) button (). An audio signal is input to the acoustic microphone arrays and a vibration signal is input to the single vibration microphone. The audio signal is detected and compared to the vibration signal to determine a high noise environment. The single vibration microphone () controls beam formation of the acoustic microphone arrays in high noise environments based on predetermined noise thresholds being exceeded and selecting an optimum acoustic microphone pair from the arrays to direct a null targeted at the noise source.
