person to another, and depends on the duration of
exposure. The U.S. Government's Occupational

Safety and Healt Administration (OSHA) has established
the maximum sound pressure levels that can be with
stood without causing damage, which are shown in the
table below. According to the OSHA regulations, any
exposure over the maximum limits indicated in the table
can reduce the hearing capacity of a person. To prevent
potentially dangerous exposure to high sound pressure
levels, anyone subjected to such levels must use
suitable protection. When an RCF product capable of
producing high sound levels is being used, it is
therefore necessary to wear ear plugs or protective
earphones when the limits shown in the table are
exceeded.
