National Center for Environmental Health

CDC’s National Center for Environmental Health (NCEH) plans, directs, and coordinates a program to protect the American people from environmental hazards. We promote a healthy environment and prevent premature death,  avoidable illness and disability caused by non-infectious, non-occupational environmental and related factors. We are especially committed to safeguarding the health of vulnerable populations – such as children, the elderly, and people with disabilities – from certain environmental hazards.

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.
