当这些婴儿处于稳定的生理状态并准备出院时，从重症监护室（ICN）的毕业生中获得听觉脑干反应（ABR）。强度范围从ABR阈值到80 dB nHL，所有记录均在隔音室中进行。这里回顾的数据来自585名婴儿，他们的听力可能正常，根据双侧ABR阈值为30 dB nHL或更低，为了确保人口统计的估计不受耳朵之间的高度相关性的影响，大多数分析中只使用左耳的数据。孕龄（CA）与ABR潜伏期之间的相关性大于胎龄（GA）或实足年龄（CHA）与相同潜伏期之间的相关性。将数据分为六个CA组进行进一步分析。所有反应成分潜伏期的分布形状相似，并依赖于CA，表现出有序的潜伏期随年龄的增加而减少。这些分布与正态分布无显著差异，并且与正态分布拟合良好。因此，可以从平均值和标准差获得对平均值的准确估计。结果表明，在评价ABR潜伏期时，考虑CA是重要的。
Auditory brainstem responses (ABR) were obtained from graduates of an intensive care nursery (ICN) when those babies were in stable physiological states and ready for hospital discharge. Intensity ranged from ABR threshold to 80 dB nHL, and all recordings were made in a sound-isolated chamber. The data reviewed here are from 585 babies having presumably normal hearing, based upon bilateral ABR thresholds of 30 dB nHL or less. To insure that estimates of population statistics were not biased by high correlations between ears, only the data from the left ears were used in most analyses. Larger correlations were observed between conceptional age (CA) and ABR latencies than between either gestational age (GA) or chronological age (CHA) and the same latencies. Data were grouped into six CA groups for further analyses. Distributions of all response-component latencies were similar in shape and depended upon CA, showing orderly decreases in latency with increasing age. None of these distributions differed significantly from normal, and they were well fitted by normal ogives. Thus, accurate estimates of percentiles can be obtained from the means and standard deviations. The results indicate that it is important to take CA into account when evaluating ABR latencies.
