中文摘要: |
本文探讨了耳声发射及其分类、特性、目前存在的问题和相关研究方法,并提出一种改进的小波阈值处理方法,它是基于一
种多分辨分析小波阈值去噪,在传统的软、硬阈值去噪基础上设立两个变量,通过调节这两个变量有效地达到去除噪声的效果。

英文摘要: |
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.
Key words: OAE; Signal Processing; Threshold ofWavelet |
