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.
