Screening tympanometry disclosed abnormalities in as many as 66% of unselected kindergarten children, including 29% with type B tympanograms. Abnormalities were more frequent in February than September and more frequent in boys than girls. Abnormalities often subsided spontaneously within six weeks. Tympanometric abnormalities were not found more frequently in a small group of children with allergic respiratory disease.
对未筛选的幼儿园儿童进行鼓室导抗图检查发现，多达66%的儿童存在异常，其中29%呈B型鼓室导抗图。2月的异常情况比9月更常见，男孩比女孩更常见。异常情况通常在六周内自行消退。在一小群患有过敏性呼吸道疾病的儿童中，鼓室导抗图异常并未更频繁地出现。
