Existing approaches to managing acoustic feedback in hearing aids attempt to increase attenuation in the feedback path by means of acoustic modifications or by decreasing gain. A new method of controlling feedback, Digital Feedback Suppression (DFS), has been made possible by digital signal processing and is available in a software-based commercial hearing aid. In this method, the hearing aid is able to monitor its input for feedback, and adds a cancellation signal when feedback is detected. The advantage of DFS is that feedback is eliminated without altering the frequency response of the hearing aid. In this presentation, the working principle of the DFS system will be explained and contrasted with other methods of feedback management. In addition, results of independent studies on the effect of the system will be presented, and recommendations for clinical usage will be discussed.
