Can Ear Wax Affect a Hearing Test? What to Know Before Your Appointment

Aarti Raicha • September 28, 2026

If you have a hearing test coming up and suspect that your ears are blocked with wax, you may wonder whether it could affect your results.

The short answer is that a significant earwax build-up can affect your hearing and may need to be dealt with as part of the assessment process.

That does not mean you should try to clean your ears before every hearing test. In fact, putting cotton buds or other objects into the ear can make a wax blockage worse.

A proper hearing assessment starts with understanding what is happening in and around the ear. If wax is present, your audiologist can consider whether it is likely to interfere with the assessment and advise you on the appropriate next step.

Can Ear Wax Affect a Hearing Test?

Yes, it can.

Sound needs to travel through the ear canal before reaching the eardrum. If the canal is significantly blocked by earwax, less sound may pass through normally.

Earwax build-up is a recognised cause of hearing loss, particularly when the ear feels blocked or full.

That matters during a hearing test because the purpose of the assessment is to understand how well you are hearing and, where possible, what may be contributing to any hearing difficulty.

If wax is blocking the ear canal, the audiologist needs to know it is there when assessing and interpreting your hearing.

NICE recommends removing earwax when it is contributing to hearing loss or other symptoms, or when it prevents examination of the ear.

Why Does Ear Wax Affect Hearing?

Earwax itself is normal.

It helps protect the ear canal, and in most people it gradually moves out of the ear naturally. A problem develops when too much wax builds up and blocks the canal.

A blockage can make sounds seem quieter or muffled. You might also notice a feeling of pressure or fullness.

The NHS lists hearing loss, earache or a blocked feeling, tinnitus and vertigo among the possible symptoms of earwax build-up.

For some people, that reduced hearing is temporary and improves once the blockage is dealt with.

However, it is important not to assume that every hearing problem is caused by wax. You can have earwax and an underlying hearing problem at the same time.

That is why examining the ear and carrying out the right hearing checks are more useful than simply assuming that clearing the wax will solve everything. If you are not sure which one you are dealing with, our guide to the difference between blocked hearing and actual hearing loss explains how the two usually feel.

What Happens If Ear Wax Is Found Before Your Hearing Test?

Finding wax does not automatically mean that your whole appointment has been wasted or that every hearing assessment has to be cancelled.

The first step is to establish how much wax is present and whether it is likely to interfere with examination or testing.

An audiologist can look inside the ear using an otoscope. This helps them assess the ear canal and eardrum where visible and identify issues such as significant wax blockage.

If the wax needs to be removed, the appropriate method will depend on the individual ear.

NICE lists microsuction, electronic ear irrigation and other methods such as manual removal as options when carried out by a trained practitioner with the correct equipment and after checking whether the method is suitable. You can read more about how these compare in the types of ear wax removal available in London.

Once the ear canal is clear, the hearing assessment can provide a better picture of how you are hearing without a significant wax blockage getting in the way.

Should You Remove Ear Wax Before a Hearing Test?

Not automatically.

If you already know that you regularly experience heavy wax build-up, it can be useful to mention this when booking your hearing appointment. The clinic can then advise you on what to do.

What you should not do is start digging inside your ears to make sure they are "clean" before the test.

Cotton buds, fingers and other objects can push wax further into the ear canal. NICE advises adults not to clean their ears by inserting small objects such as cotton buds into the canal. There is more on this in why DIY ear wax removal fails and what to do instead.

You should also be careful about trying treatments without knowing whether they are suitable for your ears. For example, Guy's and St Thomas' NHS Foundation Trust advises against using shop or pharmacy ear products where there is a chance of a perforated eardrum.

If you are unsure, having the ear checked is a safer starting point.

Can Ear Wax Make Your Hearing Seem Worse Than It Is?

A significant wax blockage can reduce hearing because it interferes with sound travelling through the ear canal.

That means someone may notice that speech sounds muffled, the television needs to be louder, or one ear seems quieter.

But there is an important distinction.

Removing wax tells us what your hearing is like without that blockage. If your hearing improves and returns to normal, wax may have been responsible for much of the problem.

If hearing remains reduced after the wax has been removed, there may be another cause that needs to be investigated.

The NHS advises people to seek medical advice if they have received treatment for earwax build-up but their hearing has not returned.

This is one reason a hearing test can be valuable after wax removal when hearing still does not seem right.

Wax Blockage or Hearing Loss? A Quick Comparison

The two can feel surprisingly alike from the inside. This table sets out the usual differences, though only an examination and a hearing test will tell you for certain.

What you notice Ear wax blockage Underlying hearing loss
How it starts Often fairly quickly, sometimes after a shower or swim Usually gradual, over months or years
How the ear feels Full, plugged or under pressure Often feels normal, with no sense of blockage
How sound seems Muffled, as if you are wearing an earplug Speech is heard but harder to make out, especially in noise
One ear or both Commonly one ear, though both can be affected Often both ears, but not always
What the otoscope shows Wax visible in the ear canal Ear canal may be clear
After wax removal Hearing usually improves Hearing stays reduced and needs further assessment

What If Your Hearing Is Still Poor After Ear Wax Removal?

It is easy to assume that another piece of wax must still be hiding in the ear.

Sometimes wax does remain, but that is not the only possibility. If this sounds familiar, you may find our article on why your ear still feels blocked after wax removal useful.

The ear can be examined again to establish whether the canal is clear. If it is, a hearing test can help assess your hearing more closely.

This is particularly worth considering if you:

  • still struggle to follow conversations
  • find yourself increasing the television volume
  • frequently ask people to repeat themselves
  • notice one ear hears differently from the other
  • continue to experience tinnitus or other hearing concerns

Persistent hearing difficulty should not simply be treated as recurring wax without checking.

Sudden hearing loss is different again. If hearing suddenly drops in one or both ears, or gets noticeably worse over a short period, NHS guidance recommends urgent medical help.

Can You Have Ear Wax Removal and a Hearing Test at the Same Appointment?

Whether both can be completed during one visit will depend on what is found when your ears are examined, the amount and condition of the wax, and what is appropriate for you.

Ealing Hearing provides both hearing assessments and professional ear wax removal, so the relationship between the two can be considered rather than treating them as completely separate issues.

If wax is identified, the audiologist can explain whether it should be removed and when your hearing should be tested.

Ealing Hearing offers professional ear wax removal, including microsuction, irrigation and manual removal where appropriate.

If your main concern is your hearing, you can also arrange a hearing assessment at the clinic. The website has further information on what happens during a hearing test.

For people closer to the Stanmore branch, Ealing Hearing also provides appointments locally, supporting the site's existing focus on hearing tests in Stanmore.

When Is a Hearing Test Important Even After the Wax Is Gone?

Removing a wax blockage can solve a temporary hearing problem, but it cannot correct hearing loss caused by something else.

If you continue to have difficulty hearing once your ears are clear, a hearing assessment can help establish the extent and type of hearing difficulty.

This is particularly important because gradual hearing loss is easy to adapt to without noticing how much has changed. You may begin turning up the television, relying more heavily on lip reading or avoiding difficult listening situations without immediately recognising these as signs of a hearing problem.

A hearing test gives you clearer information instead of leaving you to guess whether wax is still responsible. Left unchecked for years, hearing loss can take a toll well beyond the ears, as we cover in how untreated hearing loss affects your brain, mood and health. The NHS also has a clear overview of the common signs of hearing loss if you want to compare what you have noticed.

Frequently Asked Questions

Can ear wax affect hearing test results?

A significant wax blockage can reduce the amount of sound passing normally through the ear canal and may therefore affect hearing assessment. The ear should be examined so the audiologist knows whether wax is likely to be relevant.

Should I clean my ears before a hearing test?

You do not need to put objects inside your ears to clean them before an appointment. Cotton buds can push wax further into the canal and should not be used for this purpose.

Can I have a hearing test if I have earwax?

It depends on the amount and position of the wax and the type of assessment being carried out. Your audiologist can examine the ears and decide whether the wax needs to be dealt with first.

Can earwax cause temporary hearing loss?

Yes. Earwax build-up can cause hearing loss when it blocks the ear canal.

What if my hearing is still poor after wax removal?

If your hearing does not return after the wax has been treated, further assessment is recommended rather than assuming that wax is still the cause.

Can I book ear wax removal and a hearing test together?

Contact Ealing Hearing when booking and explain your symptoms or concerns. The clinic can advise you on the most appropriate appointment and whether wax removal and hearing assessment can be carried out as part of your care.

If you've spent the past week tilting your head over the bathroom sink, squeezing drops into your ear, and waiting for something to happen, you already know how frustrating ear wax removal can be when it doesn't go to plan. You're not the only one stuck in that cycle. According to RNID, an estimated 2.3 million people in the UK need professional ear wax removal every year. A 2024 Healthwatch survey found that over 85% of respondents who tried to remove ear wax at home using drops were unsuccessful. That's a staggering failure rate for something most people assume they can handle themselves.  So what's going wrong? In most cases, the methods people rely on either don't address the real problem, create new complications, or attempt removal without the tools needed to do it safely. This guide breaks down the methods that consistently fail, explains why, and helps you decide when a different approach is worth considering. Why More People Are Attempting DIY Removal Than Ever There was a time when a quick visit to your GP surgery would sort out a blocked ear. That's no longer the case for millions of people across England. In 2020, NHS guidelines reclassified ear wax removal as a non-core service, meaning GP practices are no longer required to offer it. By early 2024, RNID research found that nearly 10 million people in England had lost access to free NHS ear wax removal entirely. Their 2022 report revealed that two-thirds of people with ear wax buildup were told the service was no longer available through their GP. The result is predictable. More people are turning to home remedies, pharmacy products, and the growing market of DIY ear cleaning gadgets promoted on social media. Some of these methods are harmless but ineffective. Others carry real risks. Ear Candling and the Clinical Evidence Against It Ear candles are hollow fabric cones soaked in beeswax or paraffin. You lie on your side, place the narrow end in your ear, and light the opposite end. The claim is that the flame creates a vacuum that draws wax up and out of your ear canal. After the candle burns down, the waxy residue inside the cone is presented as proof that it worked. The problem is that the residue isn't ear wax. It's melted candle wax and burned fabric. A clinical trial published in The Laryngoscope evaluated ear candling on eight ears and found that no cerumen was removed from any of them. The same researchers surveyed 122 ear, nose, and throat specialists and documented 21 injuries caused by the procedure, including burns to the face and ear, blockages caused by dripped candle wax entering the canal, and eardrum perforation. Despite this evidence, ear candles remain widely available online and in health shops. If you've tried them and felt like your hearing improved briefly, the warmth and relaxation of lying still may have provided temporary relief, but the wax itself hasn't gone anywhere. Social Media Ear Cleaning Tools and Why Doctors Are Raising Concerns A newer trend is the wave of ear cleaning gadgets sold online and promoted through viral videos. These include spiral-tipped picks, miniature scoops, and WiFi-connected ear cameras (endoscopes) that let you watch the inside of your ear canal on your phone screen while you scrape. The videos are undeniably satisfying to watch, and the tools look precise. But ENT specialists are increasingly speaking out about the risks. Consultant ENT surgeon Amit Parmar warned in a 2025 Midland Health advisory that these devices give people a false sense of control and can damage the ear canal, eardrum, or even the small bones of hearing behind it. Searches for "ear wax removal tools" had increased by 20% in the month before his warning was published. A separate UK audiology review of TikTok content examined videos relating to at-home ear wax removal and ranked 14 different hacks by danger level. The reviewing audiologist noted that many of the methods shown have no evidence supporting their effectiveness and that several could lead to permanent hearing loss. The core issue with all of these tools is the same. Your ear canal is roughly the width of a pencil and lined with extremely thin, sensitive skin. Even with a camera feed on your phone, you're operating without the magnification, lighting, and clinical training that professionals rely on. One slip, one sneeze, or one moment of misjudging depth can cause real injury. Home Flushing Without the Right Conditions Flushing the ear with warm water is a legitimate removal method when performed by a trained professional. Many people reason that if their GP used to do it with a syringe and warm water, they can replicate the process at home with a bulb syringe or squeeze bottle. The logic makes sense on the surface, but there are critical differences that make home flushing risky. Temperature matters more than most people realise. Water that's even slightly too cold can trigger a sudden onset of dizziness and vertigo by stimulating the vestibular system in your inner ear. Water that's too warm risks burns to the delicate canal skin. Professionals use water calibrated to body temperature for exactly this reason. Pressure is another concern. Too much force from a syringe can push water and wax against the eardrum rather than flushing it out. A study published in the BMJ found that complications from ear syringing, even when performed by trained practice staff, occurred in roughly 1 in 1,000 procedures. Those complications included eardrum perforation, canal lacerations, and failure to remove the wax at all. The final issue is visibility. At home, you can't see whether the wax is shifting, whether the angle of the water is correct, or whether your eardrum is intact before you begin. Professionals examine the ear with an otoscope before attempting any removal, which is the step that makes the entire procedure safe. How Cotton Buds and Drops Can Work Against You These are the two methods almost everyone tries first, and we've covered them in detail in our earlier post on what to do when everything you've tried has failed . The short version is that cotton buds remove surface wax but push the rest deeper, compacting it against the eardrum and turning a minor buildup into a dense plug. Over-the-counter drops work best on soft, recent wax, but once wax has hardened and impacted, drops alone rarely resolve it. If you've been using drops for more than five days without improvement, or if your ear feels more blocked since you started using cotton buds, that earlier guide walks through what's happening and why professional removal becomes the practical next step. How to Tell If Wax in Ears Is Actually Causing Your Symptoms Before committing to any removal method, it's worth confirming that wax is genuinely the issue. Several common wax in ears symptoms overlap with other conditions, and treating the wrong problem wastes time and can cause harm. The most recognisable sign of wax buildup is a drop in hearing, usually in just one ear. You might also notice a persistent fullness or plugged sensation that won't clear no matter how many times you try to pop your ear. Tinnitus (ringing, buzzing, or whooshing sounds), earache, deep itchiness in the canal, and occasional mild dizziness are also associated with impacted wax. If you're experiencing hearing loss in both ears at the same time, persistent pain that doesn't respond to over-the-counter painkillers, discharge, fever, or sudden severe vertigo, these symptoms may point to infection, eustachian tube dysfunction, or other conditions that need clinical assessment. Professional evaluation is the only reliable way to confirm the cause and make sure you're not treating wax when something else is going on. For a deeper look at how wax symptoms are commonly mistaken for other problems, our post on wax in ears symptoms people spend weeks misidentifying covers this in more detail. How to Prevent Wax Buildup So You Don't End Up Here Again Once the blockage is resolved, prevention saves you from repeating the cycle. The habits that matter most are simple but consistently overlooked. The single most effective thing you can do is stop putting anything inside your ear canal. No cotton buds, no spiral tools, no bobby pins. Clean the outer ear only, using a warm damp cloth after showering. Your ear canal is designed to clean itself through the natural outward migration of skin cells and wax, and the less you interfere with that process, the better it works. If you wear earbuds, in-ear headphones, or hearing protection regularly, give your ears breaks throughout the day. These devices block the natural exit path for wax and can gradually push it deeper with each insertion. Removing them for even short periods allows wax to migrate outward as it should. For people who naturally produce more wax or have a history of recurring buildup, a weekly routine of a few drops of olive oil or almond oil can make a meaningful difference. Lie with the treated ear facing upward for five to ten minutes, then let it drain naturally. This keeps wax soft enough to exit on its own and prevents the hardening that leads to impaction. Finally, if you've had impacted wax more than once, consider scheduling a professional check every six to twelve months. Catching early buildup before it causes symptoms is far easier and more comfortable than dealing with a full blockage. Think of it as routine maintenance for your ears, no different from regular dental check-ups for your teeth. The Bottom Line DIY ear wax removal fails for a consistent reason. Most home methods either push wax deeper, partially treat it, or attempt removal without the visibility and precision needed to do it safely. The growing number of social media tools and viral hacks hasn't changed this. If anything, it's introduced new risks to a process that was already difficult to manage at home. If you've been dealing with blocked ears, muffled hearing, or persistent wax in ears symptoms that won't respond to home treatment, professional assessment is the fastest route to relief. An experienced hearing specialist can identify the problem in seconds and clear it in minutes through safe, controlled methods like microsuction or irrigation .
