Abstract:
Audio devices and methods are provided for detecting instability in an associated feedforward audio processing system. A microphone provides a feedforward signal for processing by a feedforward filter. The processed signal may provide noise reduction and/or sound enhancement associated with the surrounding environment. The processed signal contributes to a driver signal provided to an acoustic transducer, e.g., a driver, to produce acoustic signals for a user. A processor is configured to detect an indication of instability in one or more of the signals, and to adjust a phase response of the feedforward signal path in response to detecting the indication of instability.

Claim (Index 1):
An audio device comprising:\n a microphone to provide a first signal; a processor comprising a filter, the processor configured to receive the first signal and provide a second signal, the second signal based at least in part upon processing the first signal using the filter, the second signal being an anti-noise signal; and an acoustic transducer to convert a third signal, based at least in part upon the second signal, into an acoustic signal, the third signal being a driver signal; wherein the processor is also configured to detect an indication of instability in any of the first signal, the second signal, or the third signal and to adjust a phase response of the filter in response to detecting the indication of instability, the adjusted phase response being a fixed bandwidth fixed gain phase adjustment.
