Three hundred ten randomly selected male shipyard workers, with an average age of 56 years, with an average of 19 years with their employer, excluding workers with evidence of other otologic or relevant neurologic disease, were analyzed in terms of hearing loss, tinnitus, vertigo, and family history of hearing loss. The audiograms showed bilateral, symmetrical mid to high frequency hearing loss with SRT of 21 db and 85 per cent PB word discrimination. Eleven per cent had a family history of hearing loss, but this did not correlate with the patients' hearing loss, tinnitus, or vertigo. Fifteen per cent of the patients gave a history of vertigo. Tinnitus occurred in 43 per cent of right ears and in 41 per cent of left ears. Statistical analysis showed that the tinnitus did not correlate with hearing loss at any frequency in the right ear but correlated significantly with hearing loss at 2000 and 3000 HZ in the left ear! These were significant but small. Multiple correlational analysis indicated.
