Hearing loss - Exposure to high sound
levels can cause permanent hearing loss.
The sound pressure level which leads to
hearing loss varies considerably from one 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 withstood 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 pres-
sure levels, anyone subjected to such levels must use
suitable protection. When an product capable of pro-
ducing 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.
