| Abstract |
The objectives of this study were to describe workplace noise exposures, risk factors for hearing loss and hearing levels among sand and gravel miners, and to determine whether full shift noise exposures resulted in changes in hearing thresholds from baseline values. A total of 317 sand and gravel miners were interviewed regarding medical history, leisure-time and occupational noise exposure, other occupational exposures and use of hearing protection. Audiometric tests were performed before the work shift and immediately after the work shift. Full shift noise dosimetry was conducted. It was found that overall, sand and gravel workers have excessive noise exposures and significant hearing loss, and demonstrate inadequate use of hearing protection. Well-designed hearing conservation programs, with reduction of noise exposure, are clearly needed. |
