Research and Implementation of Echo Cancellation in HearingAids Based on Embedded System
摘要
Abstract
Echo leads to howling in hearing aids,demolishes the hearing device and impairs the residual hearing of the patients.Adaptive echo cancellation in hearing aids based on normalized least mean squares(NLMS)algorithm was studied.By comparing the MSE,ERLE of LMS algorithm and NLMS algorithm,we found that NLMS algorithm has more preferable echo cancellation performance in digital hearing aids.In addition,NLMS algorithm was implanted into embedded platform.Experiments validate the performance of the NLMS algorithm.So it is of important practice value for echo cancellation in hearing aids.关键词
