Noise Induced Hearing Loss

Noise Induced Hearing Loss (NIHL) is an occupational disease recognized in the Workplace Safety & Insurance Act (WSIA), and compensated for by the WSIB.

NIHL is a permanent bilateral hearing loss resulting from being exposed to high levels of noise for a long time. Occupational or work-related NIHL is the result of long term exposure to hazardous noise levels in the workplace.
  • Please note that if your hearing loss is due to sudden exposure to noise, physical injury or chemical exposure, for more information you can call 416-344-1000 (TTY: 1-800-387-0050) or 1-800-387-0750, Monday to Friday from 7:30 a.m. to 5:00 p.m.. To learn more about this type of hearing loss, see WSIB policy: 15-04-01 Traumatic Hearing Loss.
NIHL is one of the most common occupational diseases, and one of the most preventable.

Our NIHL program ensures workers with occupational NIHL receive the services and equipment they need to address their hearing loss and improve their quality of life.
