Know which noises can cause damage (those at or above 85 decibels). Wear earplugs or other protective devices when involved in a loud activity (activity-specific earplugs and earmuffs are available at hardware and sporting goods stores). If you can't reduce the noise or protect yourself from it, move away from it.
