This retrospective cross-sectional study of median hearing threshold levels of males employed in two specific occupations shows that the trend with decreasing noise-induced hearing loss in Sweden during the 1970s and 1980s continues into the 1990s. In the occupational categories mechanical work and wood processing men in age groups 30-39, 40-49 and 50-59 years old examined during the time period 1971-76, 1981-86 and 1991-96 were compared. Possible explanations to the improvement might be a wider use of hearing protectors at work and less exposure to noise during military service. The results show that the awareness of noise-induced occupational hearing loss has improved but the hearing conservation programs are still necessary as hearing threshold levels in these occupational groups continue to be poorer than expected in relation to age.
