| 摘 要： | 将小波变换这种时频域信号分析方法用于人类听性脑干反应（ＡＢＲ）分析，以了解小波变换在人类ＡＢＲ信号分析中的应用价值。研究对象分为两组，正常组１４例（２８耳），感音性聋组１７例（２７耳），分别采集７５ｄＢｎＨＬ短声诱发的ＡＢＲ，用小波处理软件进行变换，将变换前后信号的时域值作配对统计处理。所得结果与豚鼠ＡＢＲ分析相似。小波变换用于人类ＡＢＲ的分析以３尺度变换最为合适，经过这种变换原信号的时域特征保持

| Abstract: | To find out the value of wavelet transform when it is applied in analysis of human's auditory brainstem responses (ABR). The subjects was clivided into two groups,one group is normal hearing subjects (14 cases,28 ears) and another is sensorial hearing loss subjects (17 cases, 27ears). ABR of the two groups was collected and represented with wavelet transform respectively.The signals of pre-and post being transferred was contrasted and dealt with statistics. Similar to the analysis of guinea pig's ABR,the wavelet transform scale 3 is mostly adequate to the analysis of human's ABR. The time's field after transforming is not changed and the emerged rate of wave I is increased, IV-V compound is divided clearly. So the measurement of I-V range is more precise.Analysing human's ABR with wavelet transform is more precise in measurement of I-V range than with former methods. |
