ABOUT NOISE-INDUCED HEARING LOSS
We experience sound in our environment every day, such as the sounds from television and radio,
people conversing, and traffic. Normally, we hear these sounds at safe levels that do not affect our hearing.
However, when we are exposed to harmful noise – sounds that are too loud or loud sounds that last a long time – sensitive structures in our inner ear can be damaged, causing noise-induced hearing loss. These sensitive structures, called hair cells, are small sensory cells that convert sound energy into electrical signals that travel to the brain. Once damaged, our hair cells cannot grow back.
