Abstract: Acoustic feedback management systems, devices and methods are described. In an aspect, an audio device may analyze a hearing profile of a user to incorporate the hearing profile into various feedback management techniques (e.g., decorrelation techniques, adaptive feedback cancellation techniques, etc.) to personalize the management of acoustic feedback for the audio device.

Abstract: Aspects of the subject technology provide for fault detection and microphone switching of audio device(s) in an audio system. In some implementations, a preferred microphone can be determined to be in a fault condition. In response to such determination, a selection of another microphone of the audio system can be initiated to become the preferred microphone.

Abstract: Aspects of the subject technology provide for calibration of audio devices in a case. In some implementations, the calibration techniques may include detecting that an audio device is docked in a case and a lid of the case is in a closed position, where the audio device is positioned in a cavity of the case. In addition, the calibration techniques may include emitting a test audio signal from a speaker of the audio device into the case. The device may include receiving, in response to the test audio signal, a received signal at a sensor inside the case. Moreover, the device may include obtaining a correction for the audio device based on the received signal.
