[Analysis for the auditory brainstem responses of human with wavelet transform].
To find out the value of wavelet transform when it is applied in analysis of human's auditory brainstem responses (ABR). The subjects was divided into two groups, one group is normal hearing subjects (14 cases, 28 ears) and another is sensorial hearing loss subjects (17 cases, 27 ears). 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.
