Power spectral analysis and digital filtration of the auditory brain stem responses to tone burst stimuli were carried out in three adult subjects with normal hearing. Three dominant peaks (peaks A. B, C), ranging in frequency 50-150, 500-600, and 1000-1100 Hz, were observed in the spectrograms of the responses to 4 kHz at 80 dB SL. Power of higher frequency components (peaks B and C) decreased markedly or disappeared completely with decreased intensity as well as decreased frequency of stimulus, while peak A around 100 Hz consistently appeared regardless of stimulus intensity or frequency. Main spectral components of the individual waves in the ABR were determined as follows: peak A for the slow positive deflection in the response, peak B for waves VI and VII, peak C for waves II and IV, and peaks B and C for waves I, III and V.
对三名听力正常的成年受试者进行了对短纯音刺激的听觉脑干反应的功率谱分析和数字滤波。在80 dB SL的4 kHz反应的频谱图中观察到三个主要峰值（峰值A、B、C），频率范围分别为50 - 150、500 - 600和1000 - 1100 Hz。随着刺激强度和频率的降低，高频成分（峰值B和C）的功率显著降低或完全消失，而100 Hz左右的峰值A无论刺激强度或频率如何始终出现。听觉脑干反应中各个波的主要频谱成分确定如下：反应中的缓慢正偏转对应峰值A，波VI和VII对应峰值B，波II和IV对应峰值C，波I、III和V对应峰值B和C。
