Abstract
Disclosed herein, among other things, are systems and methods for artifact detection and tuning of a feedback canceller. A method includes detecting an artifact of a feedback canceller during operation of a hearing device. Artifact data associated with the detected artifact is stored in a memory of the hearing device, the artifact data including information related to the detected artifact and information related to the hearing device during occurrence of the detected artifact. Artifact statistics are computed based on the stored artifact data, and the artifact data and the artifact statistics are transmitted to an external device. Comparison data is received from the external device, including results of a comparison of artifact data or artifact statistics of the hearing device to artifact data or artifact statistics of other devices. Parameters of the hearing device are automatically adjusted based on the comparison data to improve performance of the feedback canceller.
