Personal audio device, such as a wireless telephone includes a noise cancellation circuit, the circuit noise from the reference microphone signal, the injected anti sinhoeul wall outlet or the transducer output, cancellation of ambient audio sound - generating a protection signal, and the noise results. Noise-adaptive control of the anti-signal, and the electrical through the transducer from the noise cancellation circuit to estimate the acoustic path, the error microphone for measuring the output of the transducer is provided near the speaker. Noise-protection signals are generated adaptively in order to minimize the ambient audio sound at the error microphone. The processing circuit for performing adaptive noise cancellation (ANC) function is also based on and / or error in one of the microphone signals or to filter both, to deflect the adaptation of the adaptive filter in one or more frequency regions at the error microphones close to the audio sound change the information in the minimization of.
