As part of a cross-sectional prevalence study aimed towards elucidation of the relationship between physical fitness and coronary heart disease, information concerning the hearing ability and hearing disorders was included into postal questionnaires. These were distributed to 5 050 male subjects at a median age of 53 years, range 45-65 years, and employed in public and private Copenhagen companies. A random sample of subjects was drawn from the respondents and subjected to audiological examination (N = 206). The prevalence of hearing impairment, based on the criterion of an audiometric pure-tone threshold averaged over 500, 1 000, 2 000 and 4 000 Hz greater than or equal to 25 dB HL, is 35 +/- 5%, which compares fairly well with the number of 44 +/- 7% complaining of subjective hearing impairment. Only 16 +/- 5% had normal hearing sensitivity, and 38 +/- 7% had permanent, noise-induced hearing impairment. The prevalence and characteristics of hearing impairment are compared with a recent English epidemiological investigation using an identical average of pure-tone thresholds as criterion for hearing impairment. Furthermore, the present results are considered in view of different criteria for hearing impairment and their relation to subjective complaints of reduced hearing ability. Based on the anamnesis, the pure-tone audiometric data and additional tests used for topical diagnostic purposes, the prevalence of various aetiologies of hearing impairment is indicated for the male age group in question.
作为一项旨在阐明身体素质与冠心病之间关系的横断面患病率研究的一部分，有关听力和听力障碍的信息被纳入邮政调查问卷中。这些问卷被分发给哥本哈根5050名年龄中位数为53岁（范围45 - 65岁）、受雇于公共和私人公司的男性受试者。从受访者中抽取了一个随机样本进行听力检查（N = 206）。基于500、1000、2000和4000赫兹平均纯音听阈大于或等于25分贝听力级的标准，听力障碍的患病率为35±5%，这与44±7%主诉主观听力障碍的人数相当吻合。只有16±5%的人听力敏感度正常，38±7%的人有永久性噪声性听力障碍。将听力障碍的患病率和特征与最近一项以相同纯音听阈平均值作为听力障碍标准的英国流行病学调查进行了比较。此外，还根据不同的听力障碍标准及其与听力能力下降主观主诉的关系来考虑目前的结果。根据病史、纯音听力测定数据以及用于局部诊断目的的其他检查，指出了所讨论男性年龄组中听力障碍各种病因的患病率。
