This study was designed to estimate and compare measures of cochlear travelling wave delay and travelling wave velocity in normally-hearing adults. Travelling wave delay and velocity measures were estimated in 23 normally-hearing adults using three different test techniques: i) derived auditory brainstem responses (ABR); ii) derived frequency-following responses (FFR); and iii) tone-burst-evoked otoacoustic emissions (TBEOAE). Estimates from ABR and TBEOAE were comparable to each other in terms of both averaged group values and associated standard deviations. Furthermore, mean cochlear travelling wave velocity estimated from ABR and TBEOAE were comparable to published estimates. Average cochlear delays obtained using the derived FFR were significantly shorter than those obtained from the other two techniques, possibly due to the effect of cochlear microphonic contamination. Among the dependent variables investigated, measures of delay are to be preferred over velocity since the latter are based on uncertain values of cochlear distance.
本研究旨在估计和比较正常听力成年人的耳蜗行波延迟和行波速度测量值。使用三种不同的测试技术对23名正常听力成年人进行了行波延迟和速度测量：i）导出听觉脑干反应（ABR）；ii）导出频率跟随反应（FFR）；iii）短纯音诱发耳声发射（TBEOAE）。ABR和TBEOAE的测量值在平均组值和相关标准差方面彼此相当。此外，从ABR和TBEOAE估计的平均耳蜗行波速度与已发表的估计值相当。使用导出FFR获得的平均耳蜗延迟明显短于从其他两种技术获得的延迟，这可能是由于耳蜗微音污染的影响。在所研究的因变量中，延迟测量比速度测量更可取，因为后者基于耳蜗距离的不确定值。
