A new method is described for pediatric otologic exploration : cochlear acoustic emissions (CAE), and results reported of CAE recordings in 15 children with normal hearing and 31 infants at otoneurologic risk, suspected of having moderate or severe hypoacusia on conventional audiometry. Results were compared with those obtained by study of V wave threshold of AEP. The incidence of CAE in children and infants with normal hearing was 100%, the absence of CAE being related to a V ware threshold of AEP of 30 dB nHL or more. The CAE threshold is closely related to that of the V wave of AEP. The use of CAE, a rapid, non-invasive, objective audiometric method, could be a first line screening technic allowing separation, within several minutes, of a normal hearing population from one with a lesion of transmission or endocochlear apparatus with CAE V wave threshold of over 30 dB nHL. In addition, in children with a flat AEP the CAE allows study of the cochlear independently of auditory pathways.
耳蜗听觉发射（CAE），并报告了15名听力正常儿童和31名存在耳神经学风险的婴儿的CAE记录结果，这些婴儿在传统听力测试中疑似患有中度或重度听力减退。将结果与通过听觉脑干诱发电位（AEP）的V波阈值研究获得的结果进行了比较。听力正常的儿童和婴儿中CAE的发生率为100%，CAE缺失与AEP的V波阈值为30 dB nHL或更高有关。CAE阈值与AEP的V波阈值密切相关。CAE作为一种快速、无创、客观的听力测试方法，可作为一线筛查技术，在几分钟内将听力正常人群与CAE V波阈值超过30 dB nHL的传音或蜗内装置病变人群区分开来。此外，对于AEP平坦的儿童，CAE可独立于听觉通路研究耳蜗情况。
