چکیده
- 其他摘要：Background and aims Overexposure to industrial noise pollution induce hearing loss workers. Occupational hearing loss may cause interference whit oral communication, so it may increase the risk of occupational accidents in workplace as well as affects whit social activities. This study was conducted on Lavan Island, are of oil extracting regions in the south of Iran. The object of this study was to evaluate noise pollution and determining the effect of noise enclosure on noise abatement. Methods The noise sources were recognized and noise pressure level was measured by CEL- 440. Noise dose of the exposed workers in high level noise area were measured by CEL 272. Results Major noise sources were gas turbines, diesel generators, compressors, fans and gas containing pips, noise contour map revealers that noise level were higher than the recommended national exposure limit. The results of workers noise dose show that their noise exposure were higher than the recommended value, (p Conclusion By enclosing the noise sources, noise pressure levels can be lowered douse to acceptable levels but limitation of applying enclosure should be regarded.
