, A personal audio device, such as a wireless telephone generates a squelch signal from the reference microphone signal is adaptively, and inserts the squelch signal to the sub-speaker or other output transducer to cause the removal of an audio sound from the surroundings. Error near the speaker microphone is also provided in order to provide an error signal indicative of the efficiency of noise reduction. Secondary path estimation adaptive filter from the noise reduction circuit through the electric transducer - is used to estimate the acoustic path, it allows the audio source to be removed from the error signal. The adaptation of the adaptive filter is sequenced (sequencing) and the updating of their coefficient does not cause the instability or error during the update. Level of the audio source on the audio of the surrounding may be determined to determine whether the system is capable of producing a false squelch / or instability.
