unwanted sound, is one of the most pervasive occupational health exposures, and as such, requires that employers take appropriate action when exposure to employees reach certain threshold levels. It
is a by-product of many industrial processes and consists of pressure
changes in a medium (usually air), caused by vibration or turbulence.
These pressure changes produce waves emanating away from the turbulent or vibrating source. Exposure to high levels of noise has the potential to cause hearing loss. The extent of damage depends primarily on the intensity of the noise and the duration of the exposure.
Noise-induced hearing loss can be temporary or permanent. Temporary hearing loss results from short-term exposures to noise, with normal hearing returning after period of rest. Generally, prolonged exposure to high noise levels over a period of time gradually causes permanent damage.
