Screening for hearing defect by questionnaire and audiogram was undertaken in two group practices in the South-east of England in a total of 2,278 people aged 40-64 years.The prevalence of deafness in the combined populations of these two practices as measured by audiogram was found to be 5.8 per cent (+/- 0.5 per cent; one standard error). This figure is much more than estimates derived from American data for use in Britain. The prevalence of deafness was shown to increase with lower social class and age. The questionnaire was found to be unreliable for prevalence studies, but was thought to have some use as a screening instrument.There was an incidental finding of increased hearing defects in the left ears of men. The firing of rifles was felt to be a possible explanation of this.
在英格兰东南部的两个团体诊所，对2278名年龄在40至64岁之间的人进行了问卷调查和听力图检查以筛查听力缺陷。通过听力图测量，这两个诊所合并人群中的耳聋患病率为5.8%（±0.5%；一个标准误差）。这个数字远高于从美国数据推算并用于英国的估计值。耳聋患病率随社会阶层降低和年龄增长而升高。问卷调查在患病率研究中不可靠，但被认为作为筛查工具还有些用处。偶然发现男性左耳听力缺陷增多。有人认为步枪射击可能是其原因。
