HYPOTHESIS
Otoacoustic emissions provide an alternative to traditional pure tone hearing screening in a diverse grade school population.
BACKGROUND
Mandated pure tone hearing screening programs for grade school children have several significant limitations. Otoacoustic emissions have been shown to be a reliable screening test in newborns, but there are no data on screening a diverse grade school population.
METHODS
Five hundred eighty-three grade school children in four separate school populations were screened for hearing loss using the standard pure tone four-frequency protocol and transient evoked otoacoustic emissions. Students failing either test received a comprehensive audiogram by an audiologist that served as the "gold standard." Sensitivity and specificity of both tests were compared.
RESULTS
The sensitivity and specificity of pure tone screening was 87% and 80%, respectively, compared with 65% and 91% for transient evoked otoacoustic emissions.
CONCLUSION
Pure tone screening was a statistically significant better screening test for detecting hearing loss in this population of grade school children.
假设
耳声发射可为不同的小学人群提供一种替代传统纯音听力筛查的方法。
背景
针对小学儿童的法定纯音听力筛查项目存在若干重大局限性。耳声发射已被证明是新生儿可靠的筛查测试，但尚无关于筛查不同小学人群的数据。
方法
采用标准纯音四频率方案和瞬态诱发耳声发射，对四个不同学校人群中的583名小学儿童进行听力损失筛查。任何一项测试未通过的学生均由听力学家进行全面听力图检查，该检查作为“金标准”。比较了两项测试的敏感性和特异性。
结果
纯音筛查的敏感性和特异性分别为87%和80%，而瞬态诱发耳声发射的敏感性和特异性分别为65%和91%。
结论
在这群小学儿童中，纯音筛查在检测听力损失方面是一种统计学上显著更好的筛查测试。
