Lend Me Your Ears
Exposure to extremely
high noise levels may cause
permanent hearing loss. In-
dividuals vary considerably
in susceptibility to noise-
induced hearing loss, but nearly everyone
will lose some hearing if exposed to suffi-
ciently intense noise for a period of time.
The U.S. Government's Occupational
Safety and Health Administration (OSHA)
has specified the permissible noise level ex-
posures shown in this chart.

pable of producing these levels use hearing
protectors while this unit is in operation.
