| The risk of noise-induced hearing loss is often ignored until too late because: |
 |
Hearing loss causes no pain |
|
Workers may feel discomfort and/or pain from excessive noise, but not from the hearing loss |
|
The loss occurs gradually over time, so that exposed workers don’t notice the loss until significant damage has occurred |
Once damaged, hearing cannot be restored. Damaged hearing can affect job performance, health and productivity.
A new noise regulation came into effect on July 1, 2007 in Ontario which requires employers to limit worker noise exposure to 85 dBA, to put into place measures to control exposures and to post warning signs where noise exceeds 85 dBA.
Why be concerned about noise?
The Workplace Safety and Insurance Board estimates that $100 million in compensation costs have been paid out in the last decade. |

Exposure to elevated noise levels may impact the quality of life for workers and their families and may cause: |
|
Hearing Loss |
|

|
Physiological Effects |
|
Lower Productivity |
|
