The correspondence between ABR thresholds to tone pips and behavioral thresholds at 500, 1000 and 2000 Hz was studied in 13 normal and 55 hearing-impaired children, including 42 sensori-neural losses and 13 conductive losses. The children's ages ranged from 1 year 3 months to 8 years. Tone pips were provided with 2-cycle rise-fall times and 2-cycle plateaus. The correlations between the two measures were highly significant at 3 frequencies both in sensori-neural losses and conductive losses. In the subjects with sensori-neural losses, the ABR thresholds tended to be lower than the behavioral thresholds. Mean threshold differences between the ABR and behavioral audiometry at each frequency in sensori-neural losses were 1.6, 0.26 and 5.8 dB, respectively. On the other hand, in the subjects with conductive losses, the ABR thresholds were higher than the behavioral ones by 9.6, 7.8 and 7.5 dB at respective frequencies. Therefore, the hearing acuity in young children with sensori-neural losses can be predicted with accuracy from the ABR thresholds to tone-pips at 500, 1000 and 2000 Hz.
在13名正常儿童和55名听力受损儿童中研究了短纯音ABR阈值与500、1000和2000Hz行为阈值之间的对应关系，其中包括42例感音神经性听力损失和13例传导性听力损失。儿童年龄从1岁3个月到8岁。短纯音的上升-下降时间为2个周期，平台期为2个周期。在感音神经性听力损失和传导性听力损失中，这两种测量方法在3个频率上的相关性都非常显著。在感音神经性听力损失的受试者中，ABR阈值往往低于行为阈值。感音神经性听力损失中各频率ABR与行为测听的平均阈值差异分别为1.6、0.26和5.8dB。另一方面，在传导性听力损失的受试者中，各频率的ABR阈值分别比行为阈值高9.6、7.8和7.5dB。因此，可根据500、1000和2000Hz短纯音的ABR阈值准确预测感音神经性听力损失幼儿的听力敏锐度。
