Abstract:
Disclosed is a method for optimizing noise cancellation in a headset, the headset comprising a headphone and a microphone unit comprising at least a first microphone and a second microphone, the method comprising: generating at least a first audio signal from the at least first microphone, where the first audio signal comprises a speech portion from a user of the headset and a noise portion from the surroundings; generating at least a second audio signal from the at least second microphone, where the second audio signal comprises a speech portion from the user of the headset and a noise portion from the surroundings; generating a noise cancelled output by filtering and summing at least a part of the first audio signal and at least a part of the second audio signal,   where the filtering is adaptively configured to continually minimize the power of the noise cancelled output, and where the filtering is adaptively configured to continually provide that at least the amplitude spectrum of the speech portion of the noise cancelled output corresponds to the speech portion of a reference audio signal generated from at least one of the microphones.

Claim (Index 16):
A method for optimizing noise cancellation in a headset of uncalibrated microphones, the headset comprising a headphone and a microphone unit comprising at least a first microphone and a second microphone, the method comprising:\n using first and second microphones which are uncalibrated with respect to a user's mouth position; generating at least a first audio signal from the at least first microphone, where the first audio signal comprises a speech portion from a user of the headset and a noise portion from the surroundings; generating at least a second audio signal from the at least second microphone, where the second audio signal comprises a speech portion from the user of the headset and a noise portion from the surroundings; generating a noise cancelled output by filtering and summing at least a part of the first audio signal and at least a part of the second audio signal, where the filtering is adaptively configured to continually minimize the power of the noise cancelled output, and where the filtering is continually being adapted to provide that at least the amplitude spectrum of the speech portion of the noise cancelled output corresponds to the speech portion of a reference audio signal generated from at least one of the microphones without knowledge and regardless of the position of the first and second microphones with respect to the user.
