Analysis of feedback cancellation in hearing aids with Filtered-x LMS and the direct method of closed loop identification.

Feedback cancellation in hearing aids based on Filtered-X LMS is analyzed. The data used for identification of the feedback path are the output and input signals of the hearing aid. The identification is thus done in a closed loop. Tracking characteristics and bias of the optimal estimate are discus...
