A cross sectional study to determine the prevalence of hearing loss and hearing impairment was conducted on 286 male subjects from a rural area. The sample was chosen by using a simple random sampling method. Prevalence of symptoms of tinnitus, ear disease, ear drum perforation and infection of external auditory meatus was 19.0 per cent, 6.7 per cent, 3.5 per cent and 0.4 per cent respectively. Air conduction audiometry tests showed the prevalences of hearing impairment of the left, right and both ears (aged 15-30 years) were 5.9%, 8.8% and 0% respectively. The prevalence of hearing loss increased with age. The higher frequencies (> 4KHz) appeared to be more affected than the lower frequencies.
对来自农村地区的286名男性受试者进行了一项横断面研究，以确定听力损失和听力障碍的患病率。样本采用简单随机抽样方法选取。耳鸣、耳部疾病、鼓膜穿孔和外耳道感染症状的患病率分别为19.0%、6.7%、3.5%和0.4%。气导听力测试显示，左耳、右耳和双耳（15至30岁）听力障碍的患病率分别为5.9%、8.8%和0%。听力损失患病率随年龄增长而增加。高频（>4kHz）似乎比低频更容易受到影响。
