Vectorial analysis of the brain-stem auditory evoked potential (BAEP) elicited by either condensation and rarefaction stimuli was performed in 22 healthy subjects. Besides differences in latency of components III and V ('R' longer than 'C'), a significant difference was found between the directions of the vector calculated over the descending limb of wave III, with an ascending direction for 'C' responses and a contralateral direction for 'R' responses. The possible origins of these differences are discussed. It is concluded that the use of alternating or isolated single polarity clicks is not recommended, mainly when assessing integrity of central auditory pathways.
对22名健康受试者进行了由疏密刺激诱发的脑干听觉诱发电位（BAEP）的矢量分析。除了成分III和V的潜伏期存在差异（“R”长于“C”）外，在波III下降支计算的矢量方向之间也发现了显著差异，“C”反应的方向是上升的，而“R”反应的方向是对侧的。讨论了这些差异的可能来源。得出的结论是，不建议使用交替或孤立的单极性点击，主要是在评估中枢听觉通路的完整性时。
