Don’t let your hearing conservation program fall short – why the right environment matters in workplace hearing tests
By Mobile Screening CEO Simon Holt
At Mobile Screening, we’re proud to support workplaces across Australia — from major metro hubs to the most remote rural communities — with reliable, high-quality workplace hearing tests. Our specialised mobile units are fully equipped with soundproof booths that meet the strict standards of AS/NZS 1269.4:2014. It’s more than just a feature — it’s essential. But lately, we’ve noticed a trend that’s worth highlighting.
Some providers are cutting corners on testing environments
Some providers are offering hearing tests conducted in standard meeting rooms or office spaces. While this might seem convenient on the surface, it’s important to understand the risks and limitations involved.
The standard is clear — and for good reason
AS/NZS 1269.4:2014 specifies the Maximum Permissible Ambient Noise Levels (MPANLs) required for accurate hearing testing. These levels are in place to ensure that test results truly reflect a worker’s hearing ability — not the noise of air conditioning, traffic, or nearby conversations.
Even with sound-attenuating headphones, it’s virtually impossible to meet MPANLs in a regular office or meeting room. Without a certified soundproof booth, the risk of inaccurate results increases significantly.
That means potential hearing loss could go undetected — or healthy hearing could appear impaired — leading to poor decisions, unnecessary referrals, or missed early interventions.
What’s at stake?
A compromised hearing test can have serious consequences:
- False negatives can delay intervention and lead to long-term damage.
- False positives may result in unnecessary stress for workers or even unwarranted changes to their roles.
- Non-compliance with Australian standards can expose your business to legal and reputational risk.
When it comes to hearing conservation, shortcuts aren’t worth it.
A practical note
We understand that there are times when testing in a standard room may be the only practical option — particularly in extremely remote areas or when it’s simply not feasible to bring in a mobile unit.
In those situations, it’s important that the decision to test outside a booth is made by the workplace based on logistical necessity — not just because it’s the provider’s default setup. It’s a compromise, and one that should be clearly understood in terms of the potential impact on test accuracy.
What sets Mobile Screening apart
Every one of our mobile units is fitted with a purpose-built, soundproof booth that complies with AS/NZS 1269.4:2014. We also use industry-leading audiometric equipment and quality headphones that ensure reliable results, every time.
Our approach is built on accuracy, compliance, and convenience — and we bring it all directly to your site.
Questions to ask your provider
So if you’re reviewing your current provider or considering a hearing test program for the first time, make sure you ask the right questions:
- Are tests conducted in a certified soundproof booth?
- Is the environment compliant with AS/NZS 1269.4:2014?
- Can they guarantee the accuracy of their results?
