Auditory threshold using auditory brain-stem responses (ABR) was determined in 30 ears from normally-hearing infants and 16 ears from infants with sensorineural deafness. In the same population, evoked oto-acoustic emissions (EOAEs) in response to a click of 20-dB hearing level were recorded. The presence of EOAEs was correlated with ABR thresholds. Evoked oto-acoustic emissions were always present when ABR wave V threshold was equal to or below 30-dB hearing level. On the contrary, infants with ABR thresholds higher than 40-dB hearing level never had EOAEs. As the recordings of EOAEs could be obtained more rapidly than ABR thresholds (average duration: five minutes vs 40 minutes), EOAEs could hold some promise as an objective, easy, and noninvasive test for screening auditory dysfunction in infants.
利用听性脑干反应（ABR）测定了30名听力正常婴儿的30只耳以及16名感音神经性耳聋婴儿的16只耳的听阈。在同一人群中，记录了对20分贝听力级咔嗒声的诱发耳声发射（EOAE）。EOAE的存在与ABR阈值相关。当ABR波V阈值等于或低于30分贝听力级时，总是会出现诱发耳声发射。相反，ABR阈值高于40分贝听力级的婴儿从未有过EOAE。由于获取EOAE记录比获取ABR阈值更快（平均时长：5分钟对40分钟），EOAE有望成为一种客观、简便且无创的检测方法，用于筛查婴儿的听觉功能障碍。
