Abstract

The association between contralateral stimulation and evoked otoacoustic emissions (EOAEs) allows study of sound-evoked olivocochlear feedback and then of the medial olivocochlear system. A method allowing quantification of sound-evoked olivocochlear feedback is proposed. The feedback is present in almost all normal-hearing subjects, but with great interindividual variability. In sensorineural hearing loss, the feedback is present in 20 out of 21 subjects. One paradoxical clinical case is described with a unilateral increase of EOAE intensity during contralateral stimulation.

摘要

对侧刺激与诱发耳声发射（EOAE）之间的关联使得对声音诱发的橄榄耳蜗反馈以及内侧橄榄耳蜗系统的研究成为可能。本文提出了一种能够对声音诱发的橄榄耳蜗反馈进行量化的方法。几乎所有听力正常的受试者都存在这种反馈，但个体之间差异很大。在感音神经性听力损失患者中，21名受试者中有20名存在这种反馈。本文描述了一个矛盾的临床病例，该病例在对侧刺激期间出现了EOAE强度单侧增加的情况。
