离散平稳小波分析（DSWA）用于听觉诱发电位（AEPs）的波形分析是众所周知的。我们还将DSWA应用于听觉脑干反应（ABR），其中ABR是AEP的一种类型。ABR被诱发为从输入声音刺激到耳朵的10 ms期间的人脑响应。ABR是人类客观测听的重要指标之一。ABR是通过对多个波形进行平均而获得的。因此，传统的方法有时需要大约两千个波形进行平均。在本文中，DSWA被应用到平均波形的每一个过程。ABR分为快ABR和慢ABR。快速ABR可以通过仅平均10个波形来获得。另一方面，慢ABR似乎是一个自发的脑电同步信号。为了获得慢ABR，需要对300个波形进行平均。提出了一种ABR峰值延迟检测的并行处理方法。我们所提出的方法检测峰值lavonium比传统方法快六倍。
It is well known that discrete stationary wavelet analysis (DSWA) is applied to waveform analysis of auditory evoked potentials (AEPs). We also applied the DSWA to Auditory Brainstem Responses (ABRs), where an ABR is a type of AEPs. An ABR is evoked as human brain responses during 10 ms from input sound stimulation to the ears. The ABR is one of important indicators for the human objective audiometry. The ABR has been obtained by averaging many waveforms. Therefore the conventional methods sometimes need about two thousands waveforms for averaging. In this paper, the DSWA is applied to each process of averaging waveforms. The ABR consists of fast ABR and slow ABR. The fast ABR can be obtained by averaging only ten waveforms. On the other hand, the slow ABR seems to be a spontaneous electroencephalographic synchronization signal. To obtain the slow ABR needs to average three hundreds waveforms. We propose a concurrent processing method to detect peak latencies of ABR. Our proposed method detects peak latencies six times faster than the conventional methods.
