Presbycusis, a bilateral sensorineural hearing loss caused by changes in the inner ear, is related to multiple factors such as noise exposure and otologic disease. In institute-based studies, we tried to determine the incidence of presbycusis in Korean populations living in Seoul, Kyunggi and Kangwon provinces by gender and age groups. The subjects were people who had visited health promotion centers. Pure tone audiometry was done over 20 years on 6,028 subjects. In a community-based study, the subjects were elderly residents of Kanghwa-do area. There were no obvious factors that could cause hearing impairment in the subjects. For the pure tone audiometry, hearing threshold was obtained by using the six-dimension method. The incidence of presbycusis for subjects aged 65 years and older was 37.8% and 8.3% for > or = 27 dB HL criterion and > or = 41 dB HL criterion, respectively. The incidence increased with age. A statistically significant difference in the hearing threshold was found between men and women aged 65 years or older. No differences were found between the community-based study and the institute- based studies. There was a high incidence (about 40%) of presbycusis among Koreans aged 65 years or older (for > or = 27 dB HL criterion). With an aging population, we anticipate that this report could be used to provide a basic data for the study of presbycusis.
老年性聋是一种由内耳变化引起的双侧感音神经性听力损失，与噪声暴露和耳科疾病等多种因素有关。在基于机构的研究中，我们试图按性别和年龄组确定居住在首尔、京畿道和江原道的韩国人群中老年性聋的发病率。研究对象为前往健康促进中心的人群。对6028名受试者进行了20多年的纯音听力测试。在一项基于社区的研究中，研究对象是江华岛地区的老年居民。这些受试者没有明显的可能导致听力障碍的因素。对于纯音听力测试，采用六维度方法获得听力阈值。对于65岁及以上的受试者，按照≥27dB HL标准和≥41dB HL标准，老年性聋的发病率分别为37.8%和8.3%。发病率随年龄增长而增加。在65岁及以上的男性和女性之间发现听力阈值存在统计学显著差异。基于社区的研究和基于机构的研究之间未发现差异。在65岁及以上的韩国人中（按照≥27dB HL标准），老年性聋的发病率很高（约40%）。随着人口老龄化，我们预计本报告可用于为老年性聋的研究提供基础数据。
