(2.1.1) Sound Level
Permanent hearing loss may be

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.
