If conversations suddenly sound muffled, your television seems quieter than usual, or one ear feels plugged, earwax may be the reason. Earwax buildup can block sound from traveling through the ear canal, causing a temporary type of hearing loss. It can also lead to pressure, discomfort, ringing in the ears, and problems with how a hearing aid sounds or performs.

But earwax is not always the whole story. Hearing can change gradually, and the symptoms of wax buildup can overlap with other forms of hearing loss. That is why the best next step is not to guess—or reach for a cotton swab. A professional ear exam can identify a blockage, and a comprehensive hearing test can show whether your hearing returns to its expected level once the wax is safely removed.

At Blue Sky Hearing in Berkeley, we help patients understand what is affecting their hearing and what to do next, whether the answer is earwax removal, a hearing evaluation, hearing aids, or another appropriate referral.

Earwax Is Normal—Until It Blocks the Ear Canal

Earwax, also called cerumen, is part of the ear’s natural defense system. It helps protect and lubricate the ear canal while trapping dust and debris. In most people, normal jaw movement gradually helps old wax move toward the opening of the ear, where it can fall away on its own.

Sometimes that self-cleaning process does not work as it should. Wax may become packed tightly in the canal or form a complete blockage. This is known as cerumen impaction.

Some people are more likely to experience buildup, including those who:

• Naturally produce a larger amount of earwax
• Have narrow, curved, or unusually shaped ear canals
• Wear hearing aids, earbuds, or earplugs regularly
• Use cotton swabs or other objects inside the ears
• Have dry or hard earwax
• Have previously experienced recurring wax impaction

Signs You May Have Earwax Buildup

Impacted earwax does not always cause symptoms. When it does, you may notice:

• Muffled or reduced hearing, sometimes more noticeable in one ear
• A plugged, blocked, or full sensation
• Ringing or buzzing in the ear, known as tinnitus
• Ear discomfort or itching
• Hearing aid feedback or whistling
• A hearing aid that sounds weak, distorted, or inconsistent

These symptoms can have causes other than earwax. An ear exam is important because you cannot reliably diagnose an impaction based on symptoms alone.

Can Removing Earwax Restore Hearing?

When wax is physically blocking the ear canal, professional removal may produce a noticeable improvement. Sound can once again travel through the canal to the eardrum without the obstruction.

However, removing earwax cannot correct hearing loss caused by changes in the inner ear or auditory system. It is also possible to have both impacted wax and an underlying hearing loss at the same time.

This is why earwax removal and hearing testing often work best as two parts of the same hearing-health visit:

1. Your ears are examined. The audiologist checks the ear canals and eardrums for wax and other visible concerns.
2. Problematic wax is addressed. If wax is blocking the canal or could interfere with accurate testing, safe removal may be recommended.
3. Your hearing is evaluated. A comprehensive hearing test measures the softest sounds you can hear and how clearly you understand speech.
4. You receive personalized next steps. If your hearing is within the expected range, you gain a helpful baseline. If hearing loss remains, your audiologist can explain the results and discuss whether hearing aids or another solution may help.

Clearing the ear canal helps ensure that a hearing test reflects your true hearing ability rather than the temporary effect of an obstruction.

Why Cotton Swabs Are Not the Answer

It is tempting to clean a blocked ear at home, but inserting cotton swabs, hairpins, or other objects into the ear canal can push wax farther inward. These objects can also scrape the delicate ear canal or injure the eardrum.

Ear drops may be appropriate for some people, but they are not right for everyone. Do not place drops or water in an ear when you may have a perforated eardrum, ear tubes, prior ear surgery, pain, drainage, or another condition unless a qualified healthcare professional has told you it is safe.

Professional evaluation is especially important if you are unsure what is causing your symptoms or if home care has not worked.

Earwax Can Affect Your Hearing Aids, Too

For people who wear hearing aids, earwax management is part of maintaining good hearing. Because a hearing aid sits in or near the ear canal, wax can block its microphone or receiver openings. That may make the device seem weak, intermittent, or broken. Wax can also contribute to feedback—the high-pitched whistling sound some hearing aid users experience.

If your hearing aids do not sound as clear as they once did, the problem may be wax in the device, wax in the ear canal, a change in your hearing, or a combination of factors. An audiologist can check your ears, inspect and clean the devices, and verify that the hearing aids are still programmed appropriately for your hearing.

Routine ear and hearing-aid checks are particularly helpful for people with a history of recurring buildup.

When a Hearing Test Is the Right Next Step

Consider scheduling a hearing evaluation if:

• Hearing still seems muffled after wax has been removed
• You regularly ask others to repeat themselves
• Speech is difficult to follow in restaurants or groups
• You turn the television up louder than others prefer
• You hear people speaking but cannot make out the words clearly
• Family members have noticed changes in your hearing
• You have persistent tinnitus
• You have never established a baseline hearing test

A hearing test does more than tell you whether hearing loss is present. It shows which pitches are affected, how much sound must be amplified for you to hear it, and how well you understand speech. If hearing aids are appropriate, these results help guide device selection and programming around your specific hearing profile and everyday needs.

Do You Need Earwax Removal, a Hearing Test, or Both?

You do not have to figure that out before making an appointment. The first step is simply letting a hearing professional look and listen.

At Blue Sky Hearing, better hearing begins with understanding the full picture. Dr. Susanna Storm and the Berkeley audiology team provide professional earwax management, comprehensive hearing testing, personalized hearing-aid care, and ongoing support—all centered on the situations and relationships that matter most to you.

If your ears feel blocked, your hearing has changed, or your hearing aids are not performing as expected, schedule an appointment. We can determine whether earwax is standing between you and clearer sound—and, if it is not, help you understand what comes next.

Important: Sudden hearing loss—especially in one ear—requires prompt medical attention and should not be assumed to be earwax. Seek urgent evaluation for sudden or rapidly worsening hearing, severe dizziness, significant ear pain, drainage, bleeding, or symptoms following an injury.
