Correlations between the ABR (auditory brainstem response) and the variables of hearing loss, gender, head size and age were determined in simple and multiple regression analyses in 334 ears. The stepwise multiple regression analyses for waves I, III and V of the ABR was used to determine the relative importance of the variables. Regression equations were calculated for the latency of each wave. Wave I latency for all subjects is best predicted by hearing threshold at 8 kHz, gender and age, in that order. Wave III latency depends upon hearing threshold at 4 kHz, age and gender. The latency of wave V is best predicted by gender, age and head diameter with threshold at 4 kHz being of minor importance. The I-V interval depends upon head diameter and threshold at 8 and 4 kHz with age of minor importance. Hearing loss at 8 kHz would shorten the I-V interval, while a loss at 4 kHz would be expected to lengthen the interval. Correlations of these variables with the amplitude of I, III and V are also described. Latency and amplitude are correlated with different subject variables suggesting differences in their generation.
在对334只耳朵进行的简单和多元回归分析中，确定了听性脑干反应（ABR）与听力损失、性别、头围和年龄变量之间的相关性。采用ABR波I、III和V的逐步多元回归分析来确定这些变量的相对重要性。计算了每个波潜伏期的回归方程。所有受试者的波I潜伏期最好由8kHz听阈、性别和年龄依次预测。波III潜伏期取决于4kHz听阈、年龄和性别。波V潜伏期最好由性别、年龄和头径预测，4kHz阈值的重要性较小。I-V间期取决于头径以及8kHz和4kHz阈值，年龄的重要性较小。8kHz听力损失会缩短I-V间期，而4kHz听力损失预计会延长该间期。还描述了这些变量与波I、III和V振幅的相关性。潜伏期和振幅与不同的受试者变量相关，表明它们的产生存在差异。
