The electrically elicited auditory brain-stem response (EABR) has been proposed as a tool for use in cochlear implant device setting. To systematically examine the relationships of psychophysical perceptions and EABRs, implant users underwent a series of comparative measurements. The characteristics of the EABR were assessed for their predictive value in determining the subjective measures needed to set the implant device.
Characteristics of the EABR and various perceptual measures in a group of cochlear implant users served as compared variables in a correlational study.
The study was carried out in the audiology clinic of a university hospital. The audiology clinic maintained a fully equipped evoked potential laboratory, and was part of an otolaryngology department that supported a cochlear implant program.
The subjects consisted of 10 consecutively selected postlinguistically deafened adult multichannel cochlear implant users.
Morphology, latency, and amplitude measures of the EABR recordings were compared with behavioral perceptions of threshold, most comfortable and uncomfortable loudness levels.
Perceptual measures of threshold were found to be significantly related to the threshold of the EABR across subjects and electrode position. Simple linear regression analysis was used to measure the degree of the relationship. An r value of 0.89 attests to a significant relationship. The EABR wave latencies and amplitudes were found to have no significant relationship to any of the perceptual measures examined.
Although EABR cannot replace behavioral measurements for device setting, in difficult cases EABR thresholds may be used as a starting point from which to estimate settings for the device.
电诱发听觉脑干反应（EABR）已被提议作为一种用于人工耳蜗装置设置的工具。为了系统地研究心理物理感知与EABR之间的关系，人工耳蜗使用者接受了一系列比较测量。评估了EABR的特征在确定设置人工耳蜗装置所需主观测量方面的预测价值。
在一项相关性研究中，将一组人工耳蜗使用者的EABR特征和各种感知测量作为比较变量。
该研究在一家大学医院的听力诊所进行。该听力诊所设有设备齐全的诱发电位实验室，是支持人工耳蜗项目的耳鼻喉科的一部分。
受试者包括10名连续入选的语后聋成年多通道人工耳蜗使用者。
将EABR记录的形态、潜伏期和振幅测量结果与阈值、最舒适和不舒适响度水平的行为感知进行比较。
发现受试者和电极位置的阈值感知测量与EABR的阈值显著相关。使用简单线性回归分析来测量这种关系的程度。r值为0.89证明存在显著关系。发现EABR波潜伏期和振幅与所检查的任何感知测量均无显著关系。
虽然EABR不能替代用于装置设置的行为测量，但在困难情况下，EABR阈值可作为估计装置设置的起点。
