Auditory brainstem response (ABR) can be used to measure the basilar membrane traveling wave velocity (TWV). Traveling wave velocity was calculated from the latency difference between wave V of different derived ABR and the cochlear location distance between the appropriate derived band center frequency. The latency of wave V of derived ABR produced by 6 noise-masked ABR using high pass filtered noise and the location of the corresponding cochlear partition (distance from the stapes foot-plate) were measured, and five traveling wave velocities were estimated based on this parameter. Ten subjects with normal hearing, 7 patients with Meniere's disease, and 8 patients with sensorineural hearing loss were used in this study. The traveling wave velocity in the sensorineural hearing loss group was within normal limits at all frequencies, whereas the traveling wave velocity at 8 kHz in the Meniere group greatly exceeded that of the normal and sensorineural hearing loss group.
听性脑干反应（ABR）可用于测量基底膜行波速度（TWV）。行波速度是根据不同衍生ABR的V波之间的潜伏期差异以及相应衍生频段中心频率之间的耳蜗位置距离计算得出的。测量了使用高通滤波噪声的6次噪声掩蔽ABR产生的衍生ABR的V波潜伏期以及相应耳蜗分区的位置（距镫骨足板的距离），并基于该参数估计了五个行波速度。本研究纳入了10名听力正常的受试者、7名梅尼埃病患者和8名感音神经性听力损失患者。感音神经性听力损失组在所有频率下的行波速度均在正常范围内，而梅尼埃病组在8 kHz时的行波速度大大超过正常组和感音神经性听力损失组。
