An epidemiological study was carried out, based on 590 randomly selected subjects, aged from 20 to 80 years, in the province of Ostergötland in Sweden. The results obtained were similar to published results from other countries, with an overall prevalence of subjects with average hearing threshold levels over the frequencies 0.5, 1, 2 and 4 kHz (M4) equal to or exceeding 25 dB HL for the better ear (BE) of 16.9% (95% CI: 13.819.9%). For M4 BE > or = 35 dB HL, the prevalence was 7.7% (95% CI: 5.5-9.8%), for M4 BE > or = 45 dB HL, the prevalence was 3.3% (95% CI: 1.9-4.8%), and for M4 BE > or = 65 dB HL, the prevalence was 0.2% (95% Cl: 0.0-0.6%). The overall prevalence of reported tinnitus was 13.2% (95% CI: 10.5-16.0%). In the population under study, 7.7% of the subjects were estimated to benefit from a hearing aid, while the prevalence of hearing aid users was 2.4%.
在瑞典东约特兰省，针对590名年龄在20至80岁之间的随机选取受试者开展了一项流行病学研究。所获结果与其他国家公布的结果相似，在0.5、1、2和4千赫兹频率（M4）下，较好耳（BE）平均听力阈值水平等于或超过25分贝听力级（dB HL）的受试者总体患病率为16.9%（95%置信区间：13.8%-19.9%）。对于M4 BE≥35 dB HL，患病率为7.7%（95%置信区间：5.5%-9.8%）；对于M4 BE≥45 dB HL，患病率为3.3%（95%置信区间：1.9%-4.8%）；对于M4 BE≥65 dB HL，患病率为0.2%（95%置信区间：0.0%-0.6%）。报告耳鸣的总体患病率为13.2%（95%置信区间：10.5%-16.0%）。在所研究的人群中，估计7.7%的受试者可受益于助听器，而助听器使用者的患病率为2.4%。
