| Abstract: | This article describes the Otoacoustic emission and its classification,characteristics,current problems and research methods,and improved wavelet threshold method,which is based on a multi-resolution analysis of wavelet threshold about the soft and hard traditional threshold and established two variables,by adjusting these two variables effectively achieve the effect of removing noise. |
