Occupational Noise Surveys in terms of Noise-Induced Hearing Loss Regulation

Noise can be defined as annoying, physiologically or unwanted sound. Noise-induced hearing loss can occur from prolonged exposure to noise levels at or above 85 dB(A).

Compliance requirements:
Occupational Health, and Safety Act, Act No. 85 of 1993 (In accordance with the Noise Induced Hearing Loss Regulations)

Sampling Methodology:

Noise is one of the greatest risks most industries face and noise-induced hearing loss is one of the most common occupational disease for which compensation payouts are made.

According to the Noise-induced hearing loss regulations promulgated under the Occupational Health and Safety Act, all employers need to assess the risk of noise exposure for their employees. Once the risks are quantified and evidence exists that noise exposure may be at or exceed the noise rating limit of 85dB(A), a monitoring programme needs to be designed and area measurements need to be taken so that noise zones can be demarcated. Once these demarcations are made it is the responsibility of the employer to reduce noise liberation and exposure by implementing controls.
