preventing noise-induced hearing loss
... The damage done by noise depends mainly on how loud it is and on the duration of exposure. The frequency or pitch can also have some effect since high-pitched sound are more damaging than low-pitched ones. Noise may tire out the inner ear, causing temporary hearing loss. After a period of time off, ...
