Abstract :
In this paper, a band-limited adaptive feedback cancellation algorithm for hearing aids is proposed. Utilizing the characteristics of the feedback oscillation, the algorithm provides better cancellation efficiency, convergence behavior and, hence, better output sound quality than the widely-used wideband feedback cancellation schemes
