PREVENT HEARING LOSS
Just as you would take preventative measures to protect yourself from heart disease or diabetes, or your head from injury if you cycle or ski, it pays to protect yourself from occupational hearing loss and hearing problems caused by exposure to loud music, motors and gun shots.
Sounds That Can Damage Your Ears
Industrial workplace noises, gunfire, loud music and other common, everyday sounds that are louder than 85 decibels can cause permanent hearing loss. Just how loud is 85 decibels?
Recommended exposure limits to decibels vary. Most jurisdictions in Canada limit 85 dB for a full, eight-hour work shift, but it is 90 dB in Quebec and 87 dB for organizations that follow the Canadian federal noise regulations. However, to reduce your chances of hearing loss you should use adequate hearing protection if your exposure to decibels will be more than the limits in this table.
