摘要

传统的自适应反馈消除器(FBC)在减少助听器的声漏方面表现不佳。本文提出了一种改进的频域快速块最小均方(LMS)自适应反馈对消器，与时域LMS方法相比，该方法具有良好的对消效率、收敛性和更低的硬件复杂度。

A modified fast block LMS acoustic feedback cancellation for hearing aids

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.
