摘要

耳蜗声调图决定了不同频率的行波沿基底膜的峰值位置。据推测，内淋巴水肿会通过改变耳蜗隔膜的硬度（尤其是顶点）来改变声调图。在这项在少数正常耳和水肿耳中进行的探索性研究中，我们报告了使用行为音高匹配和反射耳声发射相梯度延迟测量对耳间差异的初步测量结果。

Does Endolymphatic Hydrops Shift the Cochlear Tonotopic Map?

The cochlear tonotopic map determines where along the basilar membrane traveling waves of different frequencies peak. Endolymphatic hydrops has been hypothesized to shift the tonotopic map by altering the stiffness of the cochlear partition, especially in the apex. In this exploratory study performed in a handful of normal and hydropic ears, we report preliminary measurements of interaural differences assayed using behavioral pitch-matching supplemented by measurements of reflection otoacoustic-emission phase-gradient delays.
