Hearing loss due to exposure to high levels of noise in the workplace is a serious occupational illness. In some cases the damage is only temporary, but repeated exposure to excessive noise can cause permanent damage.
Sound levels are measured in decibels (dBA). Anything below 70dBA poses no risk. 85dBA is the approximate point when extended exposure can cause hearing damage. Occupational exposure limits (OELs) for noise are typically given as the maximum duration of exposure permitted for various noise levels.
