The authoritative guide to South Africa's Noise-Induced Hearing Loss Regulations, covering 85 dBA noise zones, audiometric baseline testing, acoustic engineering controls, and SANS-approved hearing protection.
Acoustic noise zoning, audiometric baselines, and NIHL regulatory compliance.The Noise-Induced Hearing Loss Regulations establish 85 dBA normalized over an 8-hour shift as the statutory noise rating limit. Exceeding this limit triggers mandatory audiometry and PPE controls.
Following the baseline test, workers must receive a screening audiogram at least once every 12 months.
