Exposure to extremely high noise levels may
cause permanent hearing loss. Individuals vary
considerably in susceptibility to noise-induced
hearing loss but nearly everyone will lose some
hearing if exposed to sufficiently intense noise
for a period of time. The U.S. Government’s
Occupational Safety and Health Administration
(OSHA) has specified the permissible noise level
exposures shown in the following chart. According
to OSHA, any exposure in excess of these permissible

limits could result in some hearing loss. To ensure
against potentially dangerous exposure to high
sound-pressure levels, it is recommended that all
persons exposed to equipment capable of producing
high sound-pressure levels use hearing protectors
while the equipment is in operation. Earplugs or
protectors in the ear canals or over the ears must
be worn when operating the equipment in order
to prevent permanent hearing loss if exposure is in
