Patent ID: 8771166

Claim:
An implantable auditory stimulation system, comprising: a plurality of microphones, including at least a first microphone, operative to transcutaneously receive acoustic signals and generate a first microphone output signal in response thereto, and a second microphone operative to transcutaneously receive acoustic signals and generate a second output signal in response thereto; a processor, operatively interconnected to said first microphone and to said second microphone, adapted to use said first microphone output signal and said second microphone output signal to generate a drive signal; and, an implantable auditory stimulation device, operatively interconnected to said processor, adapted to stimulate an auditory system of a patient in response to said drive signal, wherein said first microphone has a first predetermined minimum sensitivity across a first predetermined frequency range, wherein said second microphone has a second predetermined minimum sensitivity across a second frequency range, and wherein said first and second predetermined frequency ranges are at least partially non-overlapping, wherein the first and second predetermined minimum sensitivities are sensitivities corresponding to a specified output signal having a given signal-to-noise ratio for an input having a given magnitude.
