There are several technical challenges to obtaining high-quality recordings of cochlear potentials in human electrocochleography (ECochG). These challenges include electrical artifacts from devices such as acoustic transducers, biological artifacts from excessive myogenic and electroencephalographic potentials, and issues associated with the placement of a tympanic membrane (TM) electrode on the eardrum. This article presents approaches for dealing with these challenges for ECochG measurement using a TM electrode. Emphasis is placed on eliminating stimulus artifact, optimizing the placement of the electrode, and comparing a custom-made electrode with a commercially-available electrode. This comparison revealed that the custom-made electrode results in greater subject comfort, superior ease of placing the electrode on the eardrum, and larger compound action potential (CAP) amplitudes.

获得高质量耳蜗电图记录的技术

在人类耳蜗电图 (ECochG) 中获得高质量的耳蜗电位记录存在一些技术挑战。这些挑战包括声换能器等设备产生的电伪影、过度肌源性和脑电电位产生的生物伪影，以及与在鼓膜上放置鼓膜 (TM) 电极相关的问题。本文介绍了使用 TM 电极应对 ECochG 测量这些挑战的方法。重点是消除刺激伪影、优化电极的放置以及将定制电极与市售电极进行比较。该比较表明，定制电极可以提高受试者的舒适度，并且可以轻松地将电极放置在耳膜上，
