摘    要:虽然非线性助听器选配算法相继被提出,但对各选配算法的研究并不充分.对常用的NAL-NL1和DSLi/o]5.0等选配算法进行了研究与仿真.首先研究了各选配算法的设计原则,并仿真分析了在各种典型听力图下,各算法所给出的声学响应特性(增益、拐点、压缩比、各频段的强调程度等),计算了客观的评价指标(响度、语音清晰度等).实...

关 键 词:非线性助听器  设计原则  NAL-NL1  DSL[i/o]5.0  声学响应特性  响度和语音清晰度

Abstract:Various fitting methods for non-linear hearing aids have been proposed.But the study of these fitting meth-ods is not sufficient,and no such work has been done in China.This paper gives the study and the simulation of com-mon fitting methods for non-linear hearing aids,such as NAL-NL1 and DSL5.0.First,it studies the design principles of these fitting methods.Then,it simulates and analysis the acoustic response characteristics of fitting methods under various typical audiograms,such as gain,knee points,compr...
Keywords:non-linear hearing aids  design principles  NAL-NL1  DSL5  0  acoustic response characteristics  loud-ness & speech intelligibility
