模拟耳声发射信号的传统去噪方法

Denoising Simulated Otoacoustic Emissions by Conventional Method

耳声发射是近年听觉生理、听觉临床、声学等领域的研究热点.本文尝试通过建立仿真耳声发射信号,再加上噪音信号,合成带噪音的模拟耳声发射信号,然后采用传统的方法进行去噪,分析去噪效果,得出传统消噪方法的误差范围.

Recently,otoacoustic emissions （OAEs） is a hot topic of auditory physiology,auditory clinic and acoustics. Th e aim of the present study is to determine the error range of OAEs denoised by conventional method,which is synthesized by mixing noisy with stimulated OAEs.
