HIGH SOUND PRESSURE LEVELS
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 sufficient
period of time. The U.S. Government’s Occupational and Health Administration (OSHA)
has specified the following permissible noise level exposures: Sound Duration Per
Day In Hours
Sound Level dBA, Slow Response
8 90
6 92
4 65
3 97
2 100
1 ½
102
1 105
½ 110
¼ or less
115
According to OSHA, any exposure in excess of the above permissible limits could result in some
hearing loss. Ear plugs or protectors to the ear canals or over the ears must be worn when operating
this amplification system in order to prevent 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.
