21.
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 danger
ous 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.
Ear plugs 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 excess of the limits set forth here:

Rigging Precautions: When mounting or suspending loudspeaker enclo-
sures, it is essential that load ratings, rigging techniques, and special
safety considerations be appropriate for the installation. Use only the
mounting/rigging points on the loudspeaker enclosure intended for
this purpose. The user must determine the load requirements, dynamic
loading, and any other contributing factors affecting the loudspeaker
installation. The user must determine the proper design factor for
specific applications and the required load rating of the connection to
structure. Comply with all applicable federal, state, and local regulations.
We strongly recommend the following rigging system practices:
• Documentation: Thoroughly document the mounting/rigging
design with detailed drawings and parts lists.
• Analysis: Have a licensed structural engineer or other qualified
professional review and approve the mounting/rigging design
before its implementation.
• Installation: Use personnel experienced and qualified for mount
ing/rigging loudspeakers in accordance with and in compliance
with all federal, state and local regulations.
DANGER: Loudspeakers should be mounted or suspended only
by persons with knowledge of the proper hardware and rigging
techniques. When stacking or pole-mounting loudspeakers, be
sure that they are stabilized and secured from falling over or being ac
cidentally pushed over. Failure to follow these precautions may result
in damage to the equipment, personal injury, or death.
