听力损失的早期发现、诊断和康复对幼儿说话、语言和识别能力的发育是非常重要的。为确定婴幼儿听力损失发生的危险年龄,本文对自发耳声发射(SOEs)和诱发耳声发射(EOEs)随妊娠期改变的发生范围、振幅和频谱等基本特性进行了研究。将32～41周的新生儿,每两周分成一组共五个年龄组,对67名(134耳)早期新生儿做了SOEs和EOEs的记录。
Early detection of hearing loss, diagnosis and rehabilitation of young children to speak, the development of language and recognition ability is very important. In order to determine the age at risk of hearing loss in infants and toddlers, the basic characteristics of spontaneous otoacoustic emissions (SOEs) and evoked otoacoustic emissions (EOEs) with respect to their occurrence, amplitude and frequency during pregnancy were studied. The 32- to 41-week-old newborns were grouped into two groups of five age groups and SOEs and EOEs were recorded for 67 (134 ears) of early-term infants.
