Audiometric Testing in WA: What Employers Need to Know About WHS Regulation 58
If your workers frequently use hearing protection because workplace noise exceeds the exposure standard, audiometric testing is no longer optional. In Western Australia, employers must understand when testing is required, how often it must occur, and what records and follow-up actions are needed to stay compliant.
Legal requirements for audiometric testing in WA
Hearing tests used to manage workplace noise exposure are now regulated under the WorkSafe WA WHS Regulations.
- The previous requirement to register baseline tests with WorkCover WA ended in 2024.
- Employers must focus entirely on meeting WHS Regulation 58 requirements.
- You must maintain suitable on-site testing records.
Many Western Australian PCBUs arrange audiometric testing only to discover their provider cannot deliver the ongoing surveillance, comparison of results over time, and practical reporting that Regulation 58 strictly requires.
Other providers can tie up staff for 30 minutes, and supply raw data without clear direction. This can leave the employer fully responsible for interpreting complex charts and figuring out the next legal steps.
The Exposure Standards Triggering Regulation 58
- Regulation 58 makes audiometric testing mandatory if workers wear earmuffs or earplugs to control noise above national exposure standards:
An 8-hour time-weighted average of 85 dB(A). - A peak noise level of 140 dB(C).
This requirement is critical for Western Australian industries where workers are regularly exposed to loud plant, machinery, fabrication tools, heavy vehicles, or processing equipment.
Key Compliance Checkpoints for WA Employers
