19.

Exposure to extremely high noise levels may cause a permanent hearing gloss.  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 time.  The U.S. Government's Occupational Safety and  Health 
Administration (OSHA) has specified the following permissible noise level exposure.

Duration Per Day In Hours

Sound Level dBA, slow response

90

92

97

100

1 ½

102

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 in 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 exceeds the limits 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.
