本文分别对正常足月新生儿组和新生儿群体（正常足月新生儿和非正常足月新生儿）畸变产物耳声发射（distortionProductotoacousticemissions，DPOAEs）的检出率进行分析，并将DPOAE技术作为新生儿听力筛查方法对新生儿群体的听功能进行检测。结果显示：①正常足月儿测试频率（f2）=1．0kHZ的DPOAES检出率低于其他各检测频率；②正常足月儿在f2=1．0，1．3，5．0kHZ测试频率的DPOAEs检出率高于TEOAEs检出率；在f2=3．1kHZ测试频率，前者低于后者；③正常足儿中，46.67％的中耳负压耳，在测试频率（f2）低于2．0kHZ的频段未检出DPOAEs；④筛查儿（正常足月儿和非正常足月儿）的DPOAEs捡出率随口龄增长而增高；⑤在围产新生儿期，DPOAE筛查通过率低于TEOAE筛查通过率，然而，在生后6周两者之间无显著差异。
In this paper, the detection rates of distortion product otoacoustic emissions (DPOAEs) in normal term neonates and neonate populations (normal full-term newborns and non-normal term newborns) were analyzed respectively, and DPOAE technology was used as a freshmen Hearing screening method to detect neonatal hearing function. The results showed that: (1) DPOAES detection rate of normal full-term children test frequency (f2) = 1.0kHZ was lower than other test frequencies; (2) normal full-term children were tested at f2 = 1.0,1.3,5.0kHZ The detection rate of DPOAEs was higher than the detection rate of TEOAEs; at the frequency of f2 = 3.1kHZ, the former was lower than the latter; ③ In normal feet, 46.67% DPOAEs were not detected in the frequency band of 2.0kHZ; ④The detection rate of DPOAEs in screening children (normal term infants and non-normal term infants) increased with the growth of the population; (5) In the perinatal neonatal period, DPOAE screening pass rate Below the TEOAE screening pass rate, however, there was no significant difference between the two at 6 weeks after birth.
