正常青年人和极年轻人的听性脑干反应（ABR）潜伏期比成年人长。因此，在评估年轻受试者时使用成人标准可能导致错误报告未受损受试者的异常。本研究通过对374例ABR正常、无听力障碍或神经系统异常危险因素的不同年龄组受试者进行ABR绝对值和峰间潜伏期测定，建立了一个新的标准数据集。将双指数函数拟合到从数据导出的多个潜伏期测量值，并从这些函数计算校正值表。儿童测量的变异性大于成人。建议的程序，使评估异常的ABR潜伏期作出所有受试者，无论年龄。
Auditory brainstem response (ABR) latencies in normal young and very young subjects are longer than in mature subjects. Use of adult norms in the assessment of young subjects may therefore result in the erroneous reporting of abnormalities in subjects who are in no way impaired. In this study a new normative data set was established by measuring ABR absolute and interpeak latencies in 374 subjects in different age groups with normal ABR and no risk factor for hearing impairment or neurological abnormality. Double exponential functions were fitted to a number of latency measures derived from the data and from those functions a table of correction values was computed. The variability in the measurements of the children is greater than that of the adults. Procedures are proposed which enable the assessment of abnormality of ABR latencies to be made for all subjects regardless of age.
