considerably in susceptibility to noise-induced hearing loss, but nearly everyone will lose some
hearing if exposed to sufficiently intense noise for a sufficient time. The U.S. Government's
Occupational Safety and Health Administration (OSHA) has specified the following permissible
noise level exposures:
Duration Per Day In Hours
8
6
4
3
2
1.5
1
0.5
0.25 or Less
According to OSHA, any exposure in excess of the above permissible limits could result in some hearing
loss. Earplugs or protectors to the ear canals or over the ears must be worn when operating this
amplification system in order to prevent a permanent hearing loss, if exposure is in excess of the limits as
set forth above. 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 such
as this amplification system be protected by hearing protectors while this unit is in operation.
