Auditory-evoked brain stem response (BSR; wave V) was studied, using tone pips at three speech frequencies (500, 1 000 and 2 000 Hz) as stimuli. The tone pips consisted of 5-ms rise-decay times without a plateau. BSR recordings were made in 10 normal subjects and in 16 subjects with impaired hearing. In the normal subjects, BSR thresholds ranged from 10 to 20 dB SL at these three frequencies. In the subjects with impaired hearing, BSR thresholds corresponded well to conventional pure-tone thresholds at each frequency in cases of low- as well as high-frequency hearing loss. In all subjects with impaired hearing, the BSR thresholds were higher by as much as 25 dB than the pure-tone thresholds. The mean differences between these two thresholds at 500, 1 000 and 2 000 Hz were 11.3 +/- 8.0, 10.9 +/- 6.2 and 10.9 +/- 7.3 dB, respectively. Thus, we conclude that the BSR is useful for objective assessment of hearing thresholds at each of these speech frequencies.
使用三个言语频率（500、1000和2000赫兹）的短音作为刺激，对听觉诱发脑干反应（BSR；V波）进行了研究。短音的上升-下降时间为5毫秒，无平台期。对10名正常受试者和16名听力受损受试者进行了BSR记录。在正常受试者中，这三个频率下的BSR阈值范围为10至20分贝感觉级。在听力受损受试者中，在低频和高频听力损失的情况下，每个频率的BSR阈值与传统纯音阈值相当吻合。在所有听力受损受试者中，BSR阈值比纯音阈值高出多达25分贝。在500、1000和2000赫兹时，这两个阈值之间的平均差异分别为11.3±8.0、10.9±6.2和10.9±7.3分贝。因此，我们得出结论，BSR有助于对这些言语频率中的每一个频率的听力阈值进行客观评估。
