It can feel strange—or even unsettling—to hear crackling or popping sounds coming from inside your ear. These noises may remind you of bubble wrap or the snap of breakfast cereal and often catch you off guard. Whether it happens when you yawn, swallow, or for no obvious reason at all, it’s a symptom worth paying attention to.
The good news? Most cases are harmless and short-lived. But if the sounds persist or come with pain or dizziness, they could signal an underlying issue that needs professional attention. Below, we’ll explore what’s really behind those strange sounds and how to get relief.
Key Takeaways

Crackling sounds are usually caused by pressure changes, fluid, or earwax
They may be harmless, but ongoing symptoms could point to infection or dysfunction
Decongestants, gentle ear care, and professional exams can help treat or diagnose the issue
What Causes Crackling in the Ear?
Let’s break down the most common reasons for that snap-crackle-pop in your ears. Most of the time, it relates to how pressure, fluid, or even muscles are moving (or not moving) properly within your ears.
Eustachian Tube Dysfunction (ETD)
Your Eustachian tubes are narrow passages that connect the middle ear to the back of your throat. They open and close regularly to keep air pressure balanced on both sides of your eardrum. You usually don’t notice this happening—except during altitude changes, like during takeoff on a flight.
But when the tubes are inflamed or blocked—often from allergies, colds, or sinus congestion—air and fluid can get trapped, and that’s when the crackling begins. Imagine a balloon slowly inflating or releasing air through a pinhole. That’s essentially what your ears are doing when trying to self-regulate.
Other symptoms of ETD can include:
-
A feeling of fullness or stuffiness in one or both ears
-
Muffled hearing
-
Mild dizziness or imbalance
In most cases, this clears up once the inflammation subsides. But chronic ETD may require medical evaluation or nasal sprays to improve drainage.
Earwax Buildup
Earwax is often misunderstood. While many people try to clean it out, earwax is actually beneficial—it traps debris and keeps your ear canal moisturized. However, if it builds up or gets pushed too far in (often by cotton swabs), it can lead to:
-
Hearing that feels “blocked” or dull
-
Sudden crackling or popping during jaw movement

Allergies and Sinus Issues
If your ears always feel off during spring or fall, seasonal allergies may be the culprit. Allergies cause swelling and excess mucus in the nose and sinuses, which in turn can clog the Eustachian tubes. This often leads to:
-
Frequent popping or bubbling sounds
-
Pressure changes during allergy flare-ups
-
Temporary changes in hearing
In these cases, managing your allergies with antihistamines or decongestants can reduce symptoms not just in your sinuses—but in your ears too.
TMJ Disorders
It might surprise you, but your jaw joint is located right next to your ears. That’s why temporomandibular joint (TMJ) disorders often cause clicking or crackling noises, especially when you chew, yawn, or clench your teeth.
TMJ disorders can also include:
-
Jaw stiffness or tenderness
-
Headaches, especially near the temples
-
A sensation of your ear being blocked or full
Stress, teeth grinding, and jaw injuries are common TMJ triggers. Gentle stretching or jaw massage may help, but chronic issues might need dental or physical therapy intervention.
Other Possible Causes
Though less common, these conditions can also lead to crackling in the ear:
-
Ear infections (otitis media): Fluid behind the eardrum may shift and pop as you move
-
Meniere’s disease: An inner ear disorder that causes vertigo, hearing loss, and pressure
-
Muscle spasms in the middle ear: These rare spasms can cause rhythmic clicking or popping
If you experience hearing loss, dizziness, or fluid drainage, always consult a hearing professional to rule out serious causes.
Is Crackling a Sign of Hearing Loss or Infection?
Not necessarily. Crackling sounds in the ear are often mechanical, meaning they stem from movement or blockage—not damage to the ear itself. That said, it’s important not to ignore persistent symptoms.
Here’s when you should see a doctor or hearing specialist:
-
Crackling lasts more than 1–2 weeks
-
You feel pain, swelling, or warmth in or around the ear
-
Hearing is noticeably reduced or sounds distorted
-
There’s fluid leaking from the ear, especially if it’s yellow or bloody
In these cases, your provider may conduct a physical exam or a hearing test to determine what’s going on.
Safe Home Remedies for Mild Ear Crackling
For occasional, non-painful crackling, home care may help relieve symptoms. Here’s what to try—and what to avoid.
Gentle Pressure Relief
Try these methods to help your ears adjust:
-
Swallow, yawn, or chew gum to encourage natural tube opening
-
Perform the Valsalva maneuver: pinch your nose, close your mouth, and gently blow to force air into the middle ear
-
Steam inhalation can also loosen mucus and help drainage
Avoid forceful or repeated Valsalva attempts, especially if you feel dizzy afterward.
Over-the-Counter Support
If congestion is the cause, you may find relief from:
-
Antihistamines (e.g., loratadine) for allergy-related inflammation
-
Decongestants (e.g., pseudoephedrine or nasal sprays) to open nasal passages
-
NSAIDs (e.g., ibuprofen) to reduce pain and swelling
Always follow dosage instructions and talk to your doctor before starting any new medication.
Addressing Earwax at Home
To gently soften wax:
-
Use a few drops of mineral oil, baby oil, or carbamide peroxide drops
-
Let it sit for 5–10 minutes, then rinse in the shower without inserting anything into the canal
Avoid this method if you’ve had eardrum perforations, swimmer’s ear, or ear tube surgery—consult a provider instead.
Treatment Options When Home Remedies Aren’t Enough
If symptoms linger or return frequently, it’s time to consult a hearing care provider or ENT. Here’s what medical evaluation may involve:
-
Otoscope exam to check the eardrum and canal
-
Tympanometry to measure pressure and fluid behind the eardrum
-
Audiogram to determine if hearing has been affected
Your provider might then recommend:
-
Antibiotics for bacterial infections
-
Prescription nasal sprays for allergy-related swelling
-
Manual earwax removal
-
TMJ treatment, including night guards, physical therapy, or jaw exercises
Learn how to read an audiogram and better understand your results.
Final Thoughts: Should You Be Worried?
Crackling ears are more common—and less serious—than many people realize. Still, they shouldn’t be ignored entirely. Pay attention to when the symptoms show up, how long they last, and whether other issues like pain or hearing changes are present.
When in doubt, trust your instincts. A quick visit to a hearing specialist or ENT can give you peace of mind—and possibly even uncover hearing loss or infections early, when they’re easiest to treat.
FAQs About Crackling in the Ear
Why does my ear crackle when I move my jaw?
This often points to TMJ involvement. The jaw joint is located close to the ear canal, and movement can create pressure that transfers to your ear and causes crackling or popping.
Can allergies make my ears crackle?
Yes. Allergies cause inflammation in your nasal passages and sinuses, which can block the Eustachian tubes and cause crackling, popping, or ear fullness.
Is it safe to pop my ears?
Yes—if done gently. Yawning, chewing gum, or using the Valsalva maneuver can help. But don’t force it or repeat it too often, especially if it causes dizziness.
Should I clean my ears to stop the crackling?
Not with cotton swabs. If earwax is causing the issue, use softening drops or consult a provider for safe removal.
When is crackling a sign of something serious?
If it lasts over two weeks, causes pain, or comes with other symptoms like hearing loss or drainage, seek medical care to rule out infections or inner ear issues.
