Noise-induced hearing loss is 100 percent preventable. You can protect your hearing by paying attention to noises above 85 decibels in loudness, which can damage your ears. These include lawnmowers, snowblowers, motorcycles, firecrackers, and loud music.

Lower the volume on portable stereos and televisions. When you are involved in a loud activity, wear earplugs or other hearing protective devices. Be sure to protect children as well. Also, steer clear of loud noises that are too close or that last too long.
