Abstract:
A pair of earphones have microphone arrays each including a front microphone and a rear microphone. A processor uses a first set of filters to combine the four microphone signals to generate a far-field signal that is more sensitive to sounds originating a short distance away from the earphones than to sounds close to the apparatus, and provides the far-field signal to the speakers for output. The processor also uses a second set of filters to combine the four microphone signals to generate a near-field signal that is more sensitive to voice signals from a person wearing the earphones than to sounds originating away from the earphones, and provides the near-field signal to a communication system.

Claim (Index 6):
The apparatus of  claim 1 , wherein the processor comprises a far-field array sub-processor for applying the first set of filters, and a communication sub-processor for applying the second set of filters, and wherein the sub-processors are configured to generate the near-field signal by:\n in the far-field array sub-processor,\n summing signals corresponding to a first one of the microphones in the first array and a first one of the microphones in the second array to form a combined front microphone signal, and \n summing signals corresponding to a second one of the microphones in the first array and a second one of the microphones in the second array to form a combined rear microphone signal; and \n in the communication sub-processor,\n filtering the combined front microphone signal to form a filtered combined front microphone signal, \n filtering the combined rear microphone signal to form a filtered combined rear microphone signal, and \n combining the filtered combined front microphone signal and the filtered combined rear microphone signal to form a directional microphone signal; \n the near-field signal comprising the directional microphone signal.
