摘要:
Various aspects include a wearable audio device having active noise reduction (ANR). In some cases, a method for processing audio signals includes receiving a noise reduction signal configured to modify an audio signal and generate a noise reduced audio signal, the noise reduction signal having a nominal loop gain; and generating an adjusted noise reduction signal in response to a detected adverse low frequency event, the adjusted noise reduction signal having a modulated loop gain configured to reduce artifacts in the noise reduced audio signal.
