How Often Should Hearing Aids Be Serviced?
Hearing aids are designed to make everyday communication easier, but like any small electronic device, they need regular care and professional attention to keep working properly.
If your hearing aids are becoming quieter, producing distorted sound, whistling, cutting out, or simply not performing as well as they used to, servicing may help identify the problem before it becomes more serious.
So, how often should hearing aids be serviced?
For many hearing aid users, a professional service or check every 6 to 12 months is a sensible general guideline. However, the ideal frequency depends on the type of hearing aids you wear, how often you use them, your earwax production, exposure to moisture, lifestyle and whether you are experiencing any problems.
Regular servicing is not necessarily about waiting until something goes wrong. Preventative checks can help keep your hearing aids clean, comfortable and functioning as well as possible.
What Does Hearing Aid Servicing Involve?
Hearing aid servicing is more than simply wiping the outside of the device.
Depending on the hearing aid style and the problems identified, a professional service may include checking the microphones, receivers, tubing, moulds, domes, battery contacts, charging system and other components.
The hearing aid may also be cleaned using specialist equipment to remove accumulated wax, dust, skin debris and moisture.
A hearing professional may check whether the hearing aid is producing the appropriate level of amplification and whether the settings still match your current hearing needs.
If your hearing has changed since your hearing aids were fitted, adjustments may also be recommended.
How Often Should Hearing Aids Be Serviced?
There is no single servicing schedule that is right for everyone.
A common recommendation is to have your hearing aids professionally checked approximately every 6 to 12 months, even if they appear to be working normally.
Some people may benefit from more frequent checks.
For example, you may need more regular servicing if you:
Use your hearing aids for most of the day
Produce a lot of earwax
Work in dusty or humid environments
Exercise frequently while wearing your hearing aids
Regularly expose your hearing aids to moisture
Have rechargeable hearing aids that are experiencing charging problems
Wear hearing aids with custom moulds
Experience frequent feedback or whistling
Have recurring hearing aid problems
If your hearing aids are used heavily every day, regular maintenance can be particularly important.
Do You Need to Service Hearing Aids If They Are Working Normally?
Yes.
One of the reasons for regular servicing is that problems are not always obvious at first.
A microphone may gradually become blocked. A wax filter may become partially obstructed. A receiver may become contaminated with debris. Battery contacts can become dirty. Moisture can accumulate inside the device.
You may simply notice that conversations are becoming slightly harder to follow.
Because these changes can happen gradually, some people assume their hearing has deteriorated when the actual problem is with the hearing aid.
A professional check can help determine whether the issue is the hearing aid, your hearing, or both.
How Do You Know Your Hearing Aids Need Servicing?
There are several warning signs that your hearing aids may need professional attention.
Your Hearing Aids Sound Quieter
If your hearing aids no longer seem as loud or powerful as they once were, there could be several possible causes.
The microphone or receiver could be blocked, the wax filter may need replacing, or the hearing aid may require cleaning.
Your hearing may also have changed.
A hearing assessment can help determine what is happening.
The Sound Is Distorted
Speech should generally sound clear and comfortable through properly functioning hearing aids.
If voices sound distorted, crackly, weak or unclear, the hearing aid may need to be checked.
Do not automatically increase the volume, as this may not solve the underlying problem.
Your Hearing Aids Keep Cutting Out
Hearing aids that repeatedly switch off, restart or cut out during use should be checked.
For hearing aids using disposable batteries, the battery may simply need replacing.
However, persistent problems could be related to battery contacts, moisture, internal components or another fault.
Rechargeable hearing aids can also develop charging or power problems that require attention.
Your Hearing Aids Are Whistling
Whistling is often referred to as hearing aid feedback.
Occasional feedback can happen in certain situations, but persistent whistling should not simply be ignored.
The cause could be earwax, a poor fit, a damaged dome or mould, changes in hearing or hearing aid settings.
A professional can identify the likely cause and make appropriate adjustments.
You Are Struggling to Hear Again
Sometimes the hearing aid is working correctly but your hearing has changed.
If you are finding conversations increasingly difficult despite wearing your hearing aids, it may be time for another hearing assessment.
Your hearing aids may then need to be reprogrammed to match your current hearing levels.
Can Earwax Affect Hearing Aid Performance?
Yes.
Earwax is one of the common reasons hearing aids may become less effective.
Wax can accumulate around the dome, receiver, sound outlet or wax filter.
If the opening becomes blocked, less sound may reach your ear.
Earwax can also contribute to feedback and changes in sound quality.
People who naturally produce a lot of earwax may therefore need more frequent hearing aid maintenance and occasional professional earwax removal.
If you suspect significant earwax build up, avoid putting cotton buds or other objects into your ears.
A trained professional can advise you on safe earwax management.
How Often Should Hearing Aid Domes Be Replaced?
Domes are small silicone pieces attached to some hearing aids.
They can become dirty, damaged or less effective over time.
The exact replacement schedule depends on the type of dome, how frequently you wear your hearing aids and how much wax or debris they are exposed to.
Your hearing professional can advise you when they should be replaced.
If a dome becomes damaged, loose or blocked, it should be replaced rather than continuing to use it.
How Often Should Hearing Aid Wax Filters Be Changed?
Wax filters help protect the receiver or sound outlet from earwax and debris.
They do not last forever.
Some people need to replace them relatively frequently, particularly if they produce a lot of earwax.
If sound suddenly becomes quieter, checking the wax filter is often worthwhile.
However, if replacing the filter does not restore normal performance, the hearing aid may require further cleaning or servicing.
What About Hearing Aid Tubing?
Traditional behind the ear hearing aids may use tubing to connect the hearing aid to an ear mould.
Over time, tubing can become hard, discoloured, cracked or blocked.
Old tubing can affect the amount of sound reaching the ear.
If you use an earmould and notice that the sound has changed, your hearing professional can inspect the tubing and replace it if necessary.
Should Hearing Aids Be Professionally Cleaned?
Yes.
Daily cleaning at home is important, but professional cleaning provides a deeper level of maintenance.
During a professional service, the hearing aid can be inspected for wax, debris and moisture that may not be obvious from the outside.
The professional can also check individual components and identify early signs of wear.
This is particularly useful if you wear your hearing aids for many hours every day.
Can Moisture Damage Hearing Aids?
Moisture is one of the things hearing aid users need to be careful about.
Sweat, humidity, rain and accidental exposure to water can all affect hearing aid performance.
Modern hearing aids may have varying levels of protection against moisture, but water resistance does not mean a hearing aid is waterproof.
You should generally avoid wearing hearing aids in the shower or swimming unless they are specifically designed and approved for that purpose.
If your hearing aids become wet, follow the manufacturer’s guidance and speak to your hearing professional if they stop working normally.
Do Rechargeable Hearing Aids Need Servicing?
Yes.
Rechargeable hearing aids still benefit from routine professional checks.
The hearing aid itself may require cleaning and inspection, while the charging system can also be checked if there are concerns about charging or battery performance.
If your rechargeable hearing aids no longer last through the day as they once did, tell your hearing professional.
Battery performance can naturally change over time, but reduced usage time can also indicate another issue.
Do Hearing Aids Need Servicing After a Hearing Test?
Not necessarily, but a hearing test can be an important part of ongoing hearing aid care.
If your hearing test shows that your hearing has changed, your hearing aids may need reprogramming.
The hearing aid itself may be functioning correctly but no longer providing amplification that is appropriate for your current hearing levels.
This is why hearing assessments and hearing aid servicing often work together.
How Long Does a Hearing Aid Service Take?
The time required depends on what needs to be done.
A straightforward cleaning and check may be relatively quick.
If the hearing aid requires repairs, replacement parts, programming changes or more extensive cleaning, it may take longer.
Your hearing professional can tell you what is required after inspecting the device.
Can Hearing Aids Be Repaired?
Many hearing aid problems can be repaired, depending on the age, condition and type of device.
Some problems can be resolved with cleaning, replacing filters, changing tubing or replacing other external components.
More complicated faults may require specialist repair.
If the hearing aid is several years old and requires expensive repairs, your hearing professional may discuss whether repairing or replacing it makes more sense.
When Should You Replace Your Hearing Aids Instead of Servicing Them?
Servicing can extend the useful life of hearing aids, but eventually replacement may become appropriate.
Replacement may be worth considering if:
Your hearing needs have changed significantly
Your hearing aids require frequent repairs
The devices are becoming unreliable
Replacement parts are difficult to obtain
The hearing aids no longer provide sufficient amplification
You would benefit from newer technology
The cost of ongoing repairs is becoming excessive
Your lifestyle has changed and your current hearing aids no longer meet your needs
There is no universal replacement date that applies to everyone.
The condition of the devices and your individual hearing needs are more important than simply their age.
Can Servicing Improve Hearing Aid Sound Quality?
It can, particularly when performance has been affected by wax, debris, moisture or worn components.
However, servicing cannot correct every problem.
If your hearing has changed, your hearing aids may need programming adjustments rather than simply cleaning.
A hearing assessment can help determine whether the issue is related to your ears, your hearing aids or both.
Should You Clean Your Hearing Aids Every Day?
Basic daily care is recommended for many hearing aid users.
At the end of the day, you can inspect the hearing aids and gently clean the appropriate external surfaces using the method recommended for your particular device.
Keep them away from unnecessary moisture and store them safely when they are not being worn.
Do not use household cleaning products, alcohol or excessive water unless specifically instructed by the manufacturer.
What Should You Never Do to Your Hearing Aids?
Avoid putting your hearing aids in water.
Do not use sharp objects to remove wax.
Do not poke microphones or receivers with pins or needles.
Do not use household cleaning chemicals.
Do not attempt to open the hearing aid yourself.
Do not force components into place.
If you are unsure how to clean or maintain your hearing aids, ask your hearing professional for advice.
Why Regular Hearing Aid Servicing Matters
Hearing aids are an important investment in your ability to communicate with family, friends, colleagues and other people around you.
Keeping them properly maintained can help ensure that you receive the benefit they are designed to provide.
Regular servicing can help identify issues such as:
Wax build up
Blocked filters
Blocked receivers
Moisture problems
Battery issues
Charging problems
Damaged tubing
Poor fit
Feedback
Changes in hearing
Programming issues
Component wear
Addressing these problems early may prevent a minor issue from becoming a major inconvenience.
What If One Hearing Aid Works Better Than the Other?
If one hearing aid suddenly sounds clearer, louder or more comfortable than the other, both devices should be checked.
There could be a simple blockage or component issue affecting one device.
However, differences between your ears can also change over time.
If one ear has experienced a significant change in hearing, a hearing assessment may be recommended.
Can Poorly Maintained Hearing Aids Affect Communication?
Yes.
Even a relatively small reduction in hearing aid performance can make conversations more difficult.
You may find yourself asking people to repeat themselves, increasing the television volume or struggling more in restaurants and busy environments.
It is easy to assume that your hearing has deteriorated.
Sometimes the problem is simply that your hearing aids need cleaning, servicing or adjustment.
How Can You Make Your Hearing Aids Last Longer?
Good everyday care can help protect your investment.
Keep your hearing aids dry.
Clean them according to the manufacturer’s instructions.
Replace wax filters when necessary.
Check domes and moulds regularly.
Store them safely when not in use.
Keep battery contacts clean.
Avoid exposing them unnecessarily to extreme temperatures.
Use the correct charging equipment.
Have them professionally checked regularly.
Deal with problems early rather than continuing to use a malfunctioning device.
How Often Should Older Adults Have Hearing Aids Serviced?
Older adults may benefit from regular servicing because handling small hearing aid components can become more difficult.
A professional can help with cleaning, filter replacement, fitting, programming and general maintenance.
If changing batteries or cleaning small components has become difficult, rechargeable hearing aids may also be worth discussing with a hearing professional.
The right solution depends on the individual’s hearing needs, dexterity, lifestyle and preferences.
Should You Service Hearing Aids Before Going on Holiday?
It can be a good idea, particularly if you rely heavily on your hearing aids.
Having your hearing aids checked before travelling can give you an opportunity to identify potential problems before you are away from your usual hearing professional.
Consider carrying essential supplies such as spare wax filters, domes and batteries if your hearing aids use disposable batteries.
If your devices are rechargeable, remember to take the appropriate charger.
Hearing Aid Servicing and Earwax Removal
Earwax and hearing aids can sometimes create a cycle where one affects the other.
Hearing aids can interfere with the natural movement of earwax out of the ear in some people.
Increased wax can then affect hearing aid performance.
If you experience repeated wax build up, professional earwax management may form part of your overall hearing care.
Removing excess wax may improve hearing aid performance and make it easier for your professional to assess your ears accurately.
When Should You Contact a Hearing Professional?
You should arrange a hearing aid check if:
Your hearing aids suddenly stop working
The sound becomes noticeably quieter
Your hearing aids repeatedly cut out
You experience persistent whistling
Speech sounds distorted
One hearing aid sounds different from the other
The devices no longer last through the day
Your rechargeable hearing aids are not charging properly
You suspect wax is blocking the sound outlet
Your hearing has changed
Your hearing aids are uncomfortable
You are struggling to understand conversations despite wearing them
If hearing changes suddenly, particularly in one ear, seek prompt medical assessment rather than assuming the hearing aid is the cause.
