Feedback suppression device and method for periodic adaptation of a feedback suppression device

摘要

A method is provided for adapting a feedback suppression device of a hearing device to a given situation in order to improve the quality of feedback suppression in hearing devices and in hearing aids in particular. In the method an adaptation procedure of the feedback suppression device is periodically activated and adaptation of the feedback suppression device is performed regularly even if a feedback detector does not detect a feedback situation. A feedback suppression device for a hearing device is also provided.
