25. Exposure to extremely high noise levels may cause a 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 time. The U.S. Government’s Occupational Safety and Health Administration (OSHA)
has specified the following permissible noise level exposures:
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 a
permanent hearing loss, if exposure is in excess of the limits as set out 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.
