These are results from a 2016 study by WorkSafe BC in British Columbia. Data was collected in 2016 from more than 160,000 hearing tests. Hearing loss can go unnoticed by a worker for years or even decades after the initial exposure or series of exposures. Since 2006 there have been more than 37,000 accepted claims for noise-induced hearing-loss in B.C. In the U.S., an estimated $242 million is spent annually on workers' compensation for hearing loss disability.
Because construction sites are so noisy, OSHA has issued specific hearing standards for construction. OSHA sets legal limits on noise exposure in the workplace, based on a worker's time weighted average over an 8 hour day. OSHA's noise permissible exposure limit (PEL) is 90 dBA for all workers for an 8 hour day. However, the National Institute for Occupational Safety and Health (NIOSH) has recommended that all worker exposures to noise should be controlled below a level equivalent to 85 dBA for eight hours to minimize occupational noise induced hearing loss. NIOSH has found that significant noise-induced hearing loss occurs at the exposure levels equivalent to the OSHA PEL.
Noise may be a problem in your workplace if:
- You hear ringing or humming in your ears when you leave work.
- You have to shout to be heard by a coworker an arm's length away.
- You experience temporary hearing loss when leaving work.
