| Resumen |
In this study, a comprehensive noise survey of four lumber mills in British Columbia, Canada, using a randomized sampling strategy was carried out, resulting in 350 full-shift personal dosimetry measurements. Sound frequency spectrum data and information on hearing protector usage were also collected. A determinants-of-exposure regression model for noise was developed. The mean exposure level was found to be 91.7 dBA, well above the exposure British Columbia limit of 85 dBA. Of 52 jobs for which more than a single observation was made, only four were below the exposure limit. Twenty-eight jobs had means over 90 dBA, and four jobs had means over 100 dBA. Although the use of hearing protectors is high, it is unlikely that this provides complete protection against noise-induced hearing loss at the observed exposures. |
