Noise is of the most widespread and underestimated of workplace hazards. Workers exposed to high noise levels are at risk of suffering permanent noise induced hearing loss. Noise at lower levels can also be a hazard.

The Victorian Occupational Health and Safety Regulations, 2007  limit exposure to 85 decibels (A) averaged over 8 hours, with a peak level of 140dB(C). If the noise level in a workplace is 88 decibels(A), then the maximum time a worker can be exposed is four hours, and so on.

Exposure to noise levels over this will lead to permanent damage.
