Abstract

Fifty audiologically normal young adults, 25 men and 25 women, were submitted to the auditory brainstem response (ABR) test. The mean latencies of the waves I, II, III, IV and V and the interpeak latencies (IPLs) I-III, I-V and III-V were calculated and compared to the normative values published by other groups. We have observed a great similarity among these values, specially in the interpeak latencies. The latencies of the principal ABR parameters were compared between the sexes showing significant differences in all the waves, particularly in the wave V. No significant correlations were found among the values when the head size and the ABR principal components latencies were confronted.

摘要

五十名听力正常的年轻成年人，25名男性和25名女性，接受了听性脑干反应（ABR）测试。计算了波I、II、III、IV和V的平均潜伏期以及峰间潜伏期（IPL）I-III、I-V和III-V，并与其他研究小组公布的标准值进行比较。我们观察到这些值之间有很大的相似性，特别是在峰间潜伏期方面。比较了两性之间主要ABR参数的潜伏期，结果显示所有波均存在显著差异，尤其是波V。当将头围大小与ABR主要成分潜伏期进行对比时，未发现这些值之间存在显著相关性。
