Industrial deafness is a form of occupational noise-induced hearing loss (NIHL) caused by prolonged exposure to loud sound in workplaces such as construction, manufacturing, mining, aviation, and heavy industry. In Australia, workplace noise is one of the most common contributors to long-term hearing changes, yet many people may not recognise the early symptoms until the loss has progressed.
That’s why it’s important to understand the early signs to protect your hearing and know when to seek a workplace hearing assessment or explore whether you may be eligible for an industrial deafness claim or compensation.
This article explains the common symptoms, how noise affects hearing over time, and what steps you can take if you suspect industrial hearing loss.
What Is Industrial Deafness?
Industrial deafness refers to permanent hearing loss caused by repeated or intense exposure to loud occupational noise. This may include:
- Machinery and tools
- Engines and motors
- Drilling, grinding and cutting equipment
- Plant rooms
- Construction sites
- Aircraft and mining operations
Over time, these sounds can damage the tiny hair cells inside the inner ear that help transmit sound signals to the brain. The result is gradual, irreversible hearing loss that often develops over many years.
7 Common Signs and Symptoms of Industrial Deafness
Below are some of the most frequent industrial deafness symptoms that workers in Australia report. Not everyone experiences all symptoms, but recognising early changes is an important step in protecting your hearing health.
1. Difficulty Hearing Speech in Background Noise
One of the earliest signs of noise-induced hearing loss is struggling to follow conversations in noisy environments, such as:
- Work sites
- Cafés
- Social gatherings
- Busy offices
You may feel that people are “mumbling”, or you can hear the voice but cannot make out the words clearly.
2. Asking People to Repeat Themselves
If you frequently find yourself saying, “Sorry, what was that?” During conversations, this may indicate reduced clarity rather than reduced volume. Industrial deafness often affects high-frequency sounds first, making speech harder to understand.
3. Turning Up the TV or Radio Volume
Another common sign is needing a louder volume than those around you. Some people also notice that they struggle more with high-pitched sounds, such as:
- Birds chirping
- Phone notifications
- Children’s voices
This is typical of NIHL patterns.
4. Ringing in the Ears After Work (Tinnitus)
Hearing ringing, buzzing or humming after noisy shifts may indicate stress on the auditory system. While tinnitus does not always mean permanent loss, persistent symptoms can be associated with long-term industrial noise exposure.
5. Muffled Hearing After Noisy Shifts
A temporary reduction in hearing, known as a temporary threshold shift, may occur after exposure to loud noise. If this becomes a recurring pattern, it may signal that the ears are not recovering fully between shifts.
6. Trouble Hearing Phone Calls
Many workers notice that they:
- Miss words during phone calls
- Struggle to hear quiet or high-pitched callers
- Hear the phone ringing, but cannot make out the speech clearly
This can be an early functional sign of industrial deafness.
7. Hypersensitivity to Loud Sounds (Hyperacusis)
Some individuals develop sensitivity or discomfort around loud sounds. This may occur alongside tinnitus or hearing loss and often reflects changes in how the auditory system processes sound.
How Industrial Deafness Is Assessed
If you suspect hearing changes from workplace noise, it may be helpful to get a comprehensive industrial deafness hearing test with an audiologist. This typically includes:
- Audiometry (hearing test): Measures hearing levels across pitches
- Tympanometry: Checks middle ear function
- Case history: Noise exposure, employment history and symptoms
- Comparison with baseline tests: If workplace WHS testing has been completed
In Australia, WHS guidelines outline audiometric testing requirements for workers exposed to hazardous noise (AS/NZS 1269). Many organisations conduct baseline and follow-up hearing checks to monitor changes over time.
Industrial Deafness Claims and Compensation in Australia
If hearing loss is linked to workplace noise, you may be eligible for an industrial deafness claim through state-based schemes such as:
- SIRA NSW (Statutory compensation criteria)
- WorkCover/WorkSafe QLD
- Other state workers’ compensation systems
Eligibility depends on factors such as:
- Degree of hearing loss
- Work history and noise exposure
- Audiological test results
- Medical and workplace documentation
An audiologist can provide the required hearing assessment for a claim, and may recommend follow-up with a GP, specialist or compensation representative depending on your circumstances.
If you’re looking for a guide on how you can claim your industrial deafness claim, Audience Hearing can help you with it when you’re in or around Mt Annan, Mollymook, Liverpool and Leppington.

Frequently Asked Questions
1. What is industrial deafness?
Industrial deafness refers to permanent hearing loss caused by long-term or repeated exposure to loud noise in the workplace. It often develops gradually and may affect speech clarity, sound awareness and overall communication.
2. What are the early symptoms of industrial deafness?
Common early signs include difficulty hearing speech in background noise, asking others to repeat themselves, turning up the TV or radio, muffled hearing after shifts, ringing in the ears and trouble hearing phone calls. Symptoms vary between individuals.
3. Can industrial deafness be reversed?
In most cases, noise-induced hearing loss is permanent. However, early detection, appropriate hearing protection and management strategies may help prevent further deterioration and support day-to-day communication.
4. How is industrial deafness diagnosed?
A qualified audiologist performs a hearing assessment that includes audiometry, tympanometry and a detailed case history. Results may be compared with previous workplace baseline tests if available.
5. Can tinnitus be a sign of industrial deafness?
Yes. Tinnitus (ringing or buzzing in the ears) may occur after noise exposure and is commonly reported by workers with noise-induced hearing loss. Persistent tinnitus should be assessed by an audiologist or GP.
6. What is a workplace hearing test?
A workplace hearing test assesses hearing levels for workers exposed to hazardous noise. Testing helps identify early changes and supports safety compliance under WHS guidelines such as AS/NZS 1269.
7. Am I eligible for an industrial deafness claim?
Eligibility varies by state and depends on factors such as degree of hearing loss, employment history, noise exposure and medical evidence. Assessment by an audiologist is typically required to support a claim. For detailed advice, workers should consult their relevant state compensation body or legal representative.
8. Which compensation schemes cover industrial deafness in Australia?
Different states operate separate systems, including SIRA NSW, WorkCover/WorkSafe QLD and other state-based workers’ compensation schemes. Each has its own criteria for hearing loss claims.
9. What should I do if I think I have industrial deafness?
If you notice changes in your hearing, book a hearing assessment with an audiologist. They can help identify whether noise exposure is contributing to your symptoms and advise on next steps, including potential referral or claim pathways if appropriate.
10. How can I protect my hearing at work?
Using correctly fitted hearing protection, reducing time spent in noisy areas, taking listening breaks and participating in regular hearing checks can help reduce the risk of ongoing noise-related hearing loss.
