Click-evoked otoacoustic emissions (OAEs) were recorded from both ears in two groups of neonates ranging in age from a few days to two months after birth. The first group consisted of 55 full-term neonates with normal developmental history and health status, including absence of middle ear disease and familial history of hearing loss. The second group consisted of 40 infants admitted to an intensive care baby unit for various pathological conditions (anoxia, prematurity, hyperbilirubinemia, meningitis). The method achieved 97% success in assessing cochlear function in the normal group; it was possible to identify a clear and reproducible response in all ears, except 3, at 70 dB SPL (i.e. approximately 30 dB nHL). The detection-threshold of OAEs was comparable to that measured in adult ears. Several babies from the second group produced no OAEs and were also tested by auditory brainstem responses (ABR): these infants demonstrated ABR thresholds higher than 30 dB nHL. OAEs provide an objective tool for a rapid and effective screening test for cochlear impairment in neonates.
对两组出生几天至两个月大的新生儿双耳进行了瞬态诱发耳声发射（OAE）检测。第一组由55名足月新生儿组成，他们发育史和健康状况正常，包括无中耳疾病和听力损失家族史。第二组由40名因各种病理状况（缺氧、早产、高胆红素血症、脑膜炎）入住重症监护病房的婴儿组成。该方法在评估正常组耳蜗功能方面成功率达97%；在70 dB SPL（即约30 dB nHL）时，除3只耳朵外，所有耳朵都能检测到清晰且可重复的反应。OAE的检测阈值与成人耳朵测得的阈值相当。第二组中的几名婴儿未产生OAE，也进行了听性脑干反应（ABR）测试：这些婴儿的ABR阈值高于30 dB nHL。OAE为新生儿耳蜗损伤的快速有效筛查测试提供了一种客观工具。
