使用鼓膜电极从 20 名听力正常的受试者和 10 名患有梅尼埃病的受试者获得耳蜗电图记录。刺激包括喀哒声和 6,000 Hz 的突发音调。两组之间的总电位 (SP) 幅度、动作电位 (AP) 幅度或 SP/AP 幅度比的结果没有显着差异。根据评估之日的症状或听力阈值来解释结果似乎并没有改善两组之间的分离。为了区分正常患者和梅尼埃病患者，已经提出了各种 SP/AP 振幅比标准。将这些建议的标准应用于我们的数据并没有成功区分两组。
Electrocochleographic recordings were obtained from 20 subjects with normal hearing and 10 subjects with Meniere's disease by using an eardrum electrode. Stimuli included clicks and 6,000-Hz tone bursts. Results were not significantly different between the two groups for summating potential (SP) amplitude, action potential (AP) amplitude, or the SP/AP amplitude ratio. Interpreting the results in light of symptoms on the date of assessment or hearing threshold did not appear to improve separation between the two groups. Various SP/AP amplitude ratio criteria have been proposed in order to separate normal patients from those with Meniere's disease. Applying these proposed criteria to our data did not successfully separate the two groups.
