World Hearing Day
World Hearing Day: March 3rd. “Check your hearing.”
There is no cure for hearing loss! Damaged inner ear cells do not grow back. Protect your hearing by avoiding loud noise such as concerts and sporting events. Use earplugs or noise-cancelling earmuffs to protect your ears. If you already have hearing loss, take steps to keep it from getting worse. Get your hearing checked.
