耳声发射的建模与小波分析

MODELING AND WAVELET ANALYSIS OF OTOACOUSTIC EMISSION SIGNALS

本文在介绍本 组前已提出的耳 声发射全耳模 型的基础上， 进一步 讨论了 瞬态诱 发耳 声发射 信号 的连续小波分析 。分析了变换算 法和基本小波 的选择，得出 其不同 频率成 分与潜 伏期 的关系 以及利 用小波变换进行 耳蜗病变部 分定 位的 可能 性。把 仿真 结果与 对临 床数 据的 类似 分析 进行 比较 ，其概貌与趋势

After a short review of the “Whole ear Model of Otoacoustic Emission” proposed by us, a further investigation on the application of Continuous Wavelet Transform to the analysis of Transient Evoked OAE signals is made. The selection of algorithm and mother wavelet are considered and the frequency latency relation curve is then obtained. The possibility of using wavelet transform to localize the defected site of cochlea is discussed. A comparison is made between the simulation result and the result obtained by similar analysis using clinical data and they are essentially consistent.
