Noise and Occupational Medicine: Common Practice Problems.

: Noise-induced hearing loss (NIHL) represents the second most common occupational disease in the US. Although the Occupational Safety and Health Administration (OSHA) has promulgated an occupational noise exposure standard and associated recordkeeping requirements, OSHA inspections increasingly document practices that violate both the noise standard and recordkeeping regulation. This paper describes five deviations from good clinical practices masking the true societal costs of NIHL, leading to missed prevention opportunities, and creating burdens for individuals and society. These include attributing NIHL to non-occupational sources, exculpating the workplace because of audiogram patterns without careful documentation, ignoring symptoms or physical examination findings, and simply denying work-relatedness, leading to employers inappropriately lining-out cases from the OSHA 300 log. The practices identified by OSHA suggest that many individuals are not following widely recognized and accepted practices when administering hearing conservation programs.
