Patent ID: 8705781

Claim:
A method comprising: receiving a first audio input signal from a first audio transducer, wherein the first audio input signal has an amplitude and a phase; receiving at least one additional audio input signal from at least one additional audio transducer, wherein the at least one additional audio input signal has an amplitude and a phase; detecting at least one of wind noise or thermal noise in at least one of the first audio input signal or the at least one additional audio input signal; and using delay-sum beamforming to reduce at least one of wind noise or thermal noise in at least one of the first audio input signal or the at least one additional audio input signal, wherein using delay-sum beamforming includes: determining whether to apply a time delay to the first audio input signal or the at least one additional audio input signal, matching the amplitude of the first audio input signal and matching the phase of the first audio input signal to produce a first matched audio input signal, matching the amplitude of the at least one additional input signal and matching the phase of the at least one additional input signal to produce at least one additional matched audio input signal, adding the first matched audio input signal and the at least one additional matched audio input signal to produce an output signal, and transmitting the output signal to an output component of a hearing prosthesis.
