Most of us take our hearing for granted. When we go home after work and when we get up in the morning, we expect to hear. Human hearing is amazingly sensitive. Our ears can distinguish 400,000 different sounds and can detect sounds so quiet they cause the eardrum to vibrate less than 1/80 millionth of an inch. But that remarkable sensitivity does not have a lifetime guarantee.

Noise-induced hearing loss is the term for hearing damaged by exposure to excessive noise. The damage to hearing caused by too much noise may not be apparent for years. Hearing loss cannot be cured, but it can be prevented.
