While investigating the possibilities of electrically induced hearing in cases of profound deafness, we observed that very often an appropriate stimulation of the cochlea could result in tinnitus cancellation. We present here a progress report on that phenomenon, including 15 subjects. Such a cancellation was restricted to tinnitus subjectively localized in the ear under test, we observed no effect on noises localized in the other ear, or centrally. This suppression occurred so long as the cochlea was stimulated and stopped when the stimulation ceased. This phenomenon was very reproducible and did not seem to affect simultaneous normal acoustic hearing. It is hypothesized that this phenomenon acts through an inhibition of abnormal activity of sensorineural elements of the electrically stimulated cochlea.
在研究深度耳聋病例中电诱发听力的可能性时，我们观察到，对耳蜗进行适当刺激常常会使耳鸣消失。在此，我们给出关于该现象的进展报告，涉及15名受试者。这种耳鸣消失仅限于主观定位在受试耳内的耳鸣，我们观察到对定位在另一只耳朵或中枢的噪声没有影响。只要刺激耳蜗，这种抑制就会发生，刺激停止时抑制也随之停止。这种现象具有很高的可重复性，而且似乎不影响同时存在的正常听觉。据推测，该现象是通过抑制电刺激耳蜗的感觉神经元件的异常活动而起作用的。
