What is an audiometric assessment?
An audiometric assessment is a hearing test that checks how well a worker hears sounds at different pitches and volumes.
The first test sets a baseline for that worker's hearing. Every monitoring test after it is compared against that baseline, so any change shows up early.
Under Australian WHS laws, a business must provide these tests for workers who frequently wear hearing protection because noise in their role exceeds the exposure standard of 85 dB(A) averaged over eight hours. The baseline is due within three months of starting the work, and monitoring tests at least every two years after that.
Regular testing picks up noise-induced hearing loss in its early stages, while there is still time to investigate the cause and strengthen noise controls before the damage becomes permanent.
Actevate offers audiometry screening with our pre-employment health assessments, so every new starter's hearing is on record.
What the test involves
The test is painless and done in a quiet space, either at a clinic or at the workplace. It usually starts with a short history of the worker's noise exposure at work and outside it, then an ear check for blockages, before the worker listens to tones through headphones.
Note: Tests must be carried out by a competent person with the training and experience to run the test and interpret the results, ideally someone who also understands workplace noise risk and the demands of the worker's role. Testing must follow AS/NZS 1269.4:2014, the Australian standard for auditory assessment.
Why hearing loss deserves a place on your risk register
Noise-induced hearing loss is the single greatest cause of permanent hearing loss in Australia, and it is also the most preventable. It builds slowly, often over years, and by the time a worker notices it the damage cannot be reversed.
- 23,693 workers compensation claims were made for hearing loss in Australia between 2015 and 2020
- 80% of those claims came from trades, labourers and machinery operators
- Close to 30,000 hearing loss claims had been lodged since 2015 by 2023, most of them from long-term exposure to hazardous noise

SafeWork NSW names manufacturing, construction and transport, logistics and warehousing among the sectors with the most hearing loss claims. If your workforce is in one of these industries, audiometric testing is very likely already part of your legal duty.
Which workers need testing
Not every worker in a noisy workplace needs a hearing test. The duty applies to workers who are frequently required to wear hearing protection to protect them from noise above the exposure standard.
Info: The exposure standard for noise is an eight-hour average of 85 dB(A), or a peak of 140 dB(C). As a rough guide, if you need to raise your voice to talk to someone one metre away, the noise level is likely to be hazardous.
Handing out earplugs does not by itself trigger the testing duty. The trigger is how often a worker relies on hearing protection because noise in their role exceeds the standard. A noise assessment is the most reliable way to confirm which roles that covers.
Tip: List every role where hearing protection is required by signage, a site rule or the standard way the job is done. That list is the starting point for your testing program and for your next noise assessment.
When tests are due
The timing is consistent across the states covered here:
- A baseline test within three months of a worker starting the work that requires hearing protection
- Monitoring tests at least every two years after that, and more often for workers with very high average exposure across a shift
When each test happens matters too. Monitoring tests are best done a few hours into a shift, so they can pick up any short-term change in hearing. Where a test finds a change, a retest after at least 16 hours away from noise shows whether that change is temporary or permanent.
NSW
NSW requires audiometric testing under section 58 of the Work Health and Safety Regulation 2025. Workers employed before 1 January 2024 had to be tested before 1 January 2026, so every existing worker in scope should now have a baseline on file.
Queensland
The requirement began on 29 July 2025. New workers need a baseline within three months, and workers who started before 29 July 2025 must be tested before 29 July 2027.
Victoria
Victoria's OHS Regulations require testing within three months, at least every two years, and at any time a health and safety representative reasonably requests it. If two or more tests within two years show a drop of 15 dB or more at 3000, 4000 or 6000 Hz, the employer must arrange a full audiological examination.
Note: If any NSW workers in scope have not yet had a baseline test, the deadline has passed. Booking those tests is the first priority.
Tip: Add audiometry to your pre-employment medical for any role that needs hearing protection. In NSW, a pre-employment medical that includes an audiometric test can count as the worker's baseline, and Queensland will accept a pre-employment test that meets its criteria.

What to do with the results
Workers receive their results straight after the test, with an explanation of what they mean. Small changes between tests are not always clinically significant, which is why the retest matters before anyone draws a conclusion.
- Temporary threshold shift: the worker is retested on another day after at least 16 hours in quiet conditions
- Permanent threshold shift: the worker should be referred to a doctor, and in NSW the shift must be reported to your workers compensation insurer
- Tinnitus reported: treated the same way as a significant shift, with a review of noise controls
Reviewing your noise controls
A significant shift is a sign that noise controls may not be working for that worker or that task. SafeWork NSW expects businesses to look first at higher-order controls, such as isolating or engineering out the noise source, before relying on hearing protection. The review should also cover:
- Tasks that may have increased the worker's noise exposure
- Whether the hearing protectors suit the noise level
- How workers are trained to fit them, and whether they wear them for the whole shift
- Ototoxic chemicals, such as some solvents, that can damage hearing and could be substituted
If a worker's hearing loss affects their ability to work safely, you need to take reasonably practicable steps to support them. That might mean visual warnings alongside audible alarms, adjusted equipment volume or alternative duties.
Tip: When one worker shows a shift, check the hearing protection fit and controls for everyone doing the same task. A shift in one person is often the first sign of a gap that affects the whole team.
Records, cost and labour hire
- Cost: the employer organises and pays for every test, and workers don't need a doctor's referral
- Records: all test reports, including updated baselines, must be kept confidential, and workers must be given a copy of their reports when their employment ends
- Labour hire: the labour hire business is responsible for arranging and paying for testing, as it knows the worker's full noise exposure history, though the host business can pay instead if both agree
Note: In NSW, hearing test reports are health records, so they are covered by the Health Records and Information Privacy Act and the State Records Act. Store them with your other medical-in-confidence records, not on a personnel file.
My take: hearing test data is your best measure of noise risk
Most of my work in injury management starts after the damage is done. Noise-induced hearing loss is one of the few conditions where you can see the injury coming years in advance, but only if you are measuring it.
That is why I encourage employers to treat audiometric results as risk data, not a compliance record. A baseline captures the hearing a worker had on day one with your business. Without it, there is no reference point when a change shows up years later, and no way to separate what happened on your watch from what came before.
Monitoring results then tell you whether your controls are protecting people in practice. Looking across a team, the pattern matters more than any single test:
- Stable results across a team are evidence your noise management is working
- Small shifts clustered in one role or site usually point to a specific task, a piece of plant or hearing protection that isn't fitting properly
Read this way, a two-yearly test becomes an early warning system that lets you fix the gap long before it turns into permanent hearing loss and a claim.
