How Noise Hurts EarsExposure to loud sounds may cause permanent physical damage to your hearing, just like heat causes a burn or a sharp object causes a cut. You can't see or feel the damage from noise, but it can be measured on hearing tests.Inside our inner ears are thousands of tiny hair cells that send hearing signals to the brain. These hair cells act like the blades of grass in your lawn -- if you walk across them too much or stomp on them too hard, they will eventually bend, break and die out. Listening to loud sounds too long or at too high a volume will damage these irreplaceable delicate hair cells resulting in permanent hearing loss. |
