Abstract :
Conventional adaptive feedback cancellers (FBC) exhibit poor performance for acoustic leakage reduction in hearing aids. In this paper, a modified frequency domain fast block least mean square (LMS) adaptive feedback canceller is proposed that provides good cancellation efficiency, convergence behavior, and more efficient hardware complexity when compared to the time domain LMS approach.
