作者分别用不同强度和不同频率的短纯音串作为刺激研究了平均听觉脑干诱发反应的功率谱。当强度为80dB SL而纯音频率分别为2千赫和4千赫时,其功率谱的频段在50赫到1300赫之间,并在50赫～150赫、500赫～600赫和1000赫～1100赫之间出现显著的峰值(分别命名为峰A、峰B和峰C)。峰与峰之间在400赫和850赫左右各有一个谷。峰和 The authors studied the average auditory brainstem response spectrum with short pure tone strings of different intensities and frequencies respectively. When the intensity is 80dB SL and the pure tone frequencies are 2 kHz and 4 kHz respectively, the frequency spectrum of the power spectrum is between 50 Hz and 1300 Hz, and the frequency range of 50 Hz to 150 Hz, 500 Hz to 600 Hz and 1000 Hz, Significant peaks appeared between 1100 Hz (named Peak A, Peak B, and Peak C, respectively). There is a valley between peak and peak at around 400 Hz and 850 Hz. Peak and
