Working on the Tools? Custom Earplugs & Industrial Hearing Tests

Why standard foam plugs are dangerous on a job site—and how our custom-fitted solutions protect your ears without blocking out the conversation.

If you work in construction, manufacturing, or on the tools across Melbourne's Northern Suburbs, you already know that noise is just part of the job. But if you are leaving your shift in Campbellfield or Epping with a high-pitched ringing in your ears, your auditory system is warning you of permanent damage.

Industrial deafness is one of the most common workplace injuries in Australia. Yet, most tradies avoid wearing hearing protection because standard foam earplugs are uncomfortable, constantly fall out, and make it impossible to hear what's going on around them.

At LAC Audiology, we provide a better way. From manufacturing premium, custom-fitted earplugs to providing comprehensive baseline hearing tests for WorkCover claims, we help industrial workers protect their hearing without compromising their safety on site.

Safe Daily Tool Exposure Limits

Select a tool below to calculate the maximum safe exposure time before permanent inner-ear nerve damage begins.

Safe Limit
4 Minutes, 43 Seconds

Angle Grinder (105 dB(A)) • CRITICAL HAZARD

Permanent high-frequency hearing nerve damage and immediate onset tinnitus (ringing) occur within minutes of continuous exposure.


Why Foam Earplugs Fail on the Job Site

The biggest complaint we hear from tradies about standard, disposable foam earplugs is that they block out everything.

When you shove a foam plug into your ear, it aggressively muffles high-frequency sounds. You can't hear your radio, you can't hear your mates talking, and most dangerously, you might not hear a warning shout or a reversing forklift. Because they are frustrating and isolate you from your surroundings, most workers end up taking them out, leaving their ears completely exposed to angle grinders, drills, and heavy machinery.

The Solution: Custom Filtered Earplugs

You shouldn't have to choose between protecting your ears and hearing your surroundings. We manufacture premium Custom Filtered Earplugs designed specifically for industrial environments.

Here is why they are the ultimate tool for your kit:

  • A Perfect, Flush Fit: We take an exact 3D medical silicone impression of your ear canal. The plug sits flush inside your ear, meaning you can comfortably wear a hardhat or earmuffs over them, and they will never fall out when you sweat.

  • Filtered Acoustics: Unlike solid foam, our filtered plugs act like a volume knob. They feature acoustic filters that block out the dangerous, concussive sounds of machinery, but still let the frequencies of human speech pass through. You can comfortably talk to the person next to you while the grinder is running.

  • Fast Turnaround: Forget waiting weeks. We manufacture Instant Filtered Earplugs in our own lab, meaning you can get fitted today and pick them up tomorrow (or we can express post them to you).

Balanced Linear Protection

Our custom earmolds feature clinical-grade acoustic membrane filters. Rather than smothering sound like foam, they attenuate both low and high frequencies equally. This gives you a balanced reduction in decibels so you can hear your mates safely.


WorkCover & Baseline Industrial Hearing Tests

If you have been working in noisy environments for years, or you constantly struggle to hear conversations in noisy pubs, the damage may have already started.

Many workers eventually need to file a WorkCover claim for industrial deafness, but to do so, you need a clinically accurate record of your hearing loss.
At LAC Audiology, we provide comprehensive, diagnostic hearing assessments.

  • Clear the Wax First: Working in dusty environments often leads to severe earwax impaction. We use microsuction to clear the dust and wax from your ears before we test you, ensuring 100% accurate results.

  • Diagnostic Precision: We use state-of-the-art diagnostic equipment to map your exact hearing profile, giving you a crucial baseline record of your hearing health for your employer or future claims.

"Standard earplugs isolate you on the job site. Custom filtered plugs protect you from the machines while keeping you connected to your mates."
