Know which noises can cause damage. Wear ear plugs when you are involved in a loud activity.
At 110 decibels, regular exposure of more than one minute risks permanent hearing loss.
At 100 decibels, no more than 15 minutes unprotected exposure recommended.
At 85 decibels, prolonged exposure to any noise above 85 decibels can cause gradual hearing loss.
