Hearing aids are precision devices, and how you use and care for them makes a genuine difference to how well they perform. Small habits and oversights can quietly undermine the results you should be getting. At Audi Hearing, we see these patterns regularly. Here are the most important mistakes to avoid.

Key Takeaways
- Inconsistent wear slows adjustment: Not wearing hearing aids regularly prevents the brain from adapting to amplified sound.
- Earwax is a leading cause of device failure: Daily cleaning and regular wax guard replacement are essential, not optional.
- Moisture causes internal damage: Exposure to sweat, humidity, and water can destroy the electronics inside hearing aids.
- Skipping follow-up appointments costs performance: Hearing thresholds change, and regular audiologist reviews keep your devices optimally programmed.
- Delaying treatment worsens outcomes: The longer hearing loss goes unaddressed, the harder the brain finds it to relearn sound processing.
1. Not Wearing Your Hearing Aids Consistently
This is the most common and most consequential mistake. Many first-time hearing aid users wear their devices for an hour or two, find the sound overwhelming, and leave them in the drawer. The problem is that the discomfort is temporary, while the cost of inconsistent wear is lasting.
Hearing aids require the brain to relearn how to process amplified sound. That process takes time, and it only happens through regular exposure. As noted in healthdirect Australia’s guidance on hearing aids and audiologist programming, it can take time for the brain to adjust to hearing aids, and adjustments from the audiologist are often needed while this process takes place. Giving up before that adjustment completes means never experiencing what the device was designed to deliver.
Practical guidance for building consistent wear:
- Start with a few hours a day in quieter environments, then gradually extend wear time.
- Aim to wear your devices during all waking hours as quickly as you comfortably can.
- If persistent discomfort occurs, contact your audiologist. It is almost always fixable with an adjustment.
- Keep a simple diary of environments where hearing feels difficult, to share with your audiologist.
2. Neglecting Daily Cleaning
Earwax is the most common cause of hearing aid malfunction and repair. Hearing aids sit inside or behind the ear canal, which means they are in constant contact with warmth, moisture, and earwax. The acidity in earwax, combined with the moisture from perspiration, can damage the internal electronics over time.
As outlined in the Ear Science Institute Australia’s guidance on care and maintenance of hearing aids, regular cleaning, replacing domes and wax filters as needed, and avoiding exposure to products like hairspray are all part of keeping devices in good condition. Most hearing aid failures that come through our clinic could have been avoided with a consistent daily cleaning routine.
A minimal but effective daily routine:
- Wipe the exterior of each device with a soft, dry cloth each evening after removal.
- Use the wax brush supplied with your device to clear any debris from the speaker opening.
- Check and replace wax guards or filters when they appear blocked or sound quality decreases.
- Do not use water, solvents, or damp cloths on the electronics themselves.
- Store devices in their case or charger overnight with the battery door open if applicable.
3. Exposing Hearing Aids to Moisture
Moisture is a significant risk for hearing aids, yet it is one of the most frequently overlooked concerns. Showering, swimming, perspiring heavily during exercise, and even stepping out into humid weather can introduce moisture into the delicate internal components.
The key steps to protect against moisture include:
- Always remove your hearing aids before showering, swimming, or using saunas.
- Use a hearing aid drying kit or electronic dehumidifier device overnight, particularly in humid climates or during warmer months.
- After exercise, wipe your devices with a dry cloth before storing them.
- If your devices do become wet, remove the battery, leave the battery door open, and allow them to dry naturally before use. Do not use a microwave or hair dryer.
Hearing Aid Repair and Batteries service at Audi Hearing handles authorised repairs for moisture-damaged and worn devices. Prevention is significantly less costly than repair or replacement.
4. Waiting Too Long to Seek Help
Research consistently shows that Australians wait far too long between noticing hearing difficulties and seeking professional assessment. That delay, sometimes measured in years, has real consequences for hearing rehabilitation outcomes.
Bluetooth connectivity has transformed what hearing aids can offer, but this technology only benefits people who have actually sought professional assessment and been fitted appropriately. Waiting means losing years of functional hearing improvement and social connection that treatment could have provided.
More than 1.3 million Australians have hearing loss that could have been prevented, and many others live with treatable hearing loss for years without acting. Hearing loss and dementia risk are increasingly linked in research, making early assessment and intervention even more important. If you have noticed that conversations are becoming harder to follow or that you frequently ask people to repeat themselves, an assessment should be the next step.
5. Skipping Follow-Up Audiologist Appointments
Many people treat hearing aids as a one-time purchase. They attend the fitting appointment, collect their devices, and assume the job is done. In reality, hearing aids require ongoing professional management to perform at their best over time.
Several factors make regular follow-up essential:
- Hearing loss is not static. Thresholds change gradually over time, and devices that are perfectly programmed at fitting may need recalibration a year later.
- Listening needs change. A new job, retirement, travel, or changes in social activity may all require different program settings.
- Wear and fit issues develop. Earmould shapes change with weight fluctuation, and tubes and domes deteriorate with regular use.
- New features and software updates become available. Professional follow-up ensures you are getting the most from your current devices.
Audiology Australia, the peak professional body representing audiologists in Australia, confirmed in 2025 that audiology will be regulated under the Australian Health Practitioner Regulation Agency (Ahpra), which further reinforces the importance of working with registered, accountable professionals for ongoing hearing care rather than treating device fitting as a transaction rather than an ongoing clinical relationship.
6. Choosing the Wrong Device Without Professional Guidance
The growth of online and over-the-counter hearing aids has given many Australians the impression that selecting a hearing aid is a straightforward consumer decision. It is not. Hearing loss varies significantly between individuals, and a device that suits one person’s audiogram, lifestyle, and ear anatomy may deliver poor results for another.
Audiologists guide device selection based on the individual’s hearing needs and preferences, as some options are better suited to certain types and levels of hearing loss. Selecting a device without this clinical guidance frequently results in poor sound quality, discomfort, feedback issues, and ultimately, devices that are not worn.
7. Ignoring Ear Health Between Audiology Appointments
Hearing aids rest in contact with the ear canal for many hours each day. Ear canal health matters to hearing aid performance. Earwax accumulation is not just a device issue. It is also an ear health issue. Cotton buds should not be used for wax removal, as they push wax further into the canal and can cause impaction or damage to the eardrum.
As outlined in healthdirect Australia’s resource on hearing loss prevention, warning signs and treatment, untreated hearing loss affects the ability to connect with the world and overall health. Regular professional ear health checks, separate from hearing aid programming reviews, support the best long-term outcomes for both ear health and device performance.

FAQs:
What happens if you don't clean your hearing aids regularly?
Earwax and debris block the speaker and microphone, reducing sound quality and eventually causing the device to malfunction.
How often should hearing aids be checked by an audiologist?
At least annually, or sooner if sound quality changes, discomfort develops, or your lifestyle changes significantly.
Can wearing hearing aids for the first time feel uncomfortable?
Yes, initially. The brain needs time to adjust to amplified sound. Consistent daily wear is the fastest path through this adjustment.
What should I do if my hearing aid gets wet?
Remove the battery, open the door, allow it to dry naturally, and contact your audiologist if it does not resume normal function.
Is it bad to put hearing aids in the wrong ear?
Yes. Each device is programmed for the hearing profile of its specific ear. Swapping them will produce incorrect amplification.
Why do hearing aids whistle or produce feedback?
Feedback usually indicates poor fit, earwax blocking the canal, or sound leaking around an improperly positioned device.
