Patent ID: 7346176

Claim:
A system for sensing and compensating for at least one error signal, the system comprising: an acoustic pick-up device having a first microphone disposed at a first distance from a desired acoustic source, and a second microphone disposed at a second distance from the desired acoustic source, each of the first microphone and the second microphone receiving acoustic signals generated from the desired acoustic source, and in response, transducing the acoustic signals into audio signals; a position estimation circuit coupled to receive the audio signals from the first microphone and the second microphone, and adapted to produce, from the audio signals of both first and second microphones, an error signal to indicate angular and/or distance mispositioning of the acoustic pick-up device relative to the desired acoustic source that results in the acoustic signals received by the acoustic pick-up device failing to achieve proper or adequate noise cancellation and resulting in the audio signals being degraded; and a controller using the error signal to compensate for the acoustic pick-up device being mispositioned by providing the audio signals from at least one of the first microphone and the second microphone to an output.
