Sound Level

Permanent hearing loss may be caused

by exposure to extremely high noise

levels. The U.S. Occupational Safety and

Health Administration (OSHA) has

specified permissible exposures to

certain noise levels. According to OSHA,

exposure to high sound pressure levels

(SPL) in excess of these limits may result

in hearing loss. When using equipment

capable of generating high SPL, use

hearing protection while such equipment

is under operation.
