查询词典 emissions

Objective To investigate the optimal time of distortion product otoacoustic emissions in newborn hearing screening and to obtain the basic properties of DPOAE in the normal newborns. Methods DPOAE were recorded 1 to 5 days postpartum in 40 ears of 20 healthy newborns with Celesta 503 Cochlear Emission Analyzer.

目的 研究新生儿畸变产物耳声发射听力筛选的最佳时机，了解正常新生儿DPOAE的基本特征；方法应用Celesta 503型耳声发射分析仪对20名正常新生儿出生后1～5天逐日进行DPOAE测试。
