Hearing loss

Noise-induced hearing loss (NIHL) is the most common permanent work-related disease in Canada. Though hearing loss typically happens gradually, damage is permanent. Research shows that hearing loss involving a lesion or disease of the inner ear or the auditory nerve is caused by many factors other than occupational noise. For typical audiograms identifying different types of hearing loss please follow this link.

Occupational risk factors include long-term exposure to high-intensity noise, acoustic trauma and head injury. Research shows that an average exposure of 85 dBA over the course of a typical workday would result in an 8%* incidence of occupational NIHL after 40 years.
