Understanding Occupational Noise Risks
Excessive workplace noise is a leading cause of hearing loss in Australian workplaces. Unmanaged noise impacts not only worker health and safety but also communication, productivity and regulatory compliance. An effective workplace noise assessment, also known as occupational noise assessment, is essential to protect your people and fulfil your legal obligations.
Why Is a Noise Assessment Required?
- Under Australian Work Health and Safety (WHS) and/or Occupational Health and Safety (OH&S) Regulations, a Person Conducting a Business or Undertaking (PCBU) must identify, assess and control risks from hazardous noise.
- Workplace noise must not exceed 85 dB(A) averaged over an 8-hour shift, or 140 dB(C) peak.
- Workplace noise assessment is required when hazardous exposures are suspected, following changes in equipment or processes, or to maintain compliance.
- If noise risks persist, a hierarchy of controls is mandated: engineering controls (such as enclosures and maintenance), administrative controls (e.g. scheduled breaks), and personal hearing protection as a last resort.
- Health surveillance, including audiometric testing, is required for workers who are required to wear hearing protection devices to control noise exposure.

Detailed measurement of noise exposure at your site, followed by clear interpretation and practical, tailored recommendations. - How frequently should noise be reassessed?
Every five years, or sooner if significant changes occur in processes, equipment, or staff feedback. - What are the legal workplace noise limits?
85 dB(A) LAeq,8h or 140 dB(C) peak, as set by Safe Work Australia and state authorities. - Is audiometric testing required for high-noise workplaces?
Yes—Two yearly testing is required at or above action levels and hearing protectors are required to minimise noise exposure. - Do you conduct workplace noise assessments in Australia?
