This descriptive study defined an effective hearing testing protocol for elementary school-aged children (N = 41). It compared the identification of hearing loss and middle ear disease using pure tone threshold audiometry with tympanometry to using pure tone threshold audiometry. Betty Neuman's Systems Model was used as the conceptual framework for this study. Results showed that a greater number of ears were identified with middle ear disease using the research protocol (n = 22) than would have been identified with middle ear disease (n = 9) using pure tone audiometry alone. The same number of ears (n = 26) were identified with hearing loss using either method. The study further demonstrates a difference between the first and second hearing test results using the specified protocol that validates the necessity for repeating the two tests after 4 weeks before making referrals.
这项描述性研究为小学年龄段儿童（N = 41）确定了一种有效的听力测试方案。它将使用纯音阈值测听法结合鼓室图来识别听力损失和中耳疾病的情况与仅使用纯音阈值测听法进行了比较。贝蒂·诺伊曼的系统模型被用作本研究的概念框架。结果表明，使用研究方案（n = 22）识别出患有中耳疾病的耳朵数量比仅使用纯音测听法（n = 9）识别出患有中耳疾病的耳朵数量更多。两种方法识别出患有听力损失的耳朵数量相同（n = 26）。该研究进一步证明了使用指定方案进行的首次和第二次听力测试结果之间存在差异，这证实了在进行转诊前有必要在4周后重复这两项测试。
