Noise Survey

Occupational noise surveys are conducted to evaluate noise rating levels at your workplace against the 85 dBA noise rating limit to quantitatively assess the risks of noise-induced hearing loss, and recommend corrective actions where necessary.

Noise is defined as unwanted, annoying or physiologically damaging sound. Prolonged exposure to workplace noise levels at or above the 85 dBA noise rating limit may cause permanent noise-induced hearing loss. Noise may also interfere with speech communication, cause annoyance and reduce the productivity of employees, which can result in fatigue and numerous other physiological and behavioural effects.

Prevent noise-related problems in the workplace

Noise-induced hearing loss hardly ever happens overnight. Rather, it accumulates over time with every unprotected exposure to hazardous noise, usually in both ears.

This progression can be detected by applying healthy hearing practices, including performing annual audiograms on employees. Audiograms can identify whether your employees are experiencing degradation in hearing, indicating permanent damage and that requires preventative action.

Noise-induced hearing loss regulations in South Africa

Every employer should have a workplace Noise Survey conducted at their premises to stay compliant with regulations in South Africa as required in terms of Sections 6 and 7 of the Noise-Induced Hearing Loss Regulations, Occupational Health and Safety Act and Sections 5, 9 and 12 of the Mine Health and Safety Act.
