That ringing, buzzing, clicking, or whooshing in your ear is almost certainly tinnitus, a phantom sound perception that affects roughly 14% of adults worldwide. The sound isn’t coming from outside your body. It’s generated by your nervous system, often in response to changes in your hearing or the structures of your ear. The specific type of noise you hear, and when it happens, points toward different causes.
What the Sound Tells You
Ear noises come in a surprising variety. A steady ringing or high-pitched tone is the most commonly reported, but people also describe buzzing, roaring, hissing, humming, whistling, and squealing. These continuous sounds typically fall under the umbrella of tinnitus and usually reflect changes in how your auditory system processes signals.
Clicking or popping that happens when you swallow or yawn is a different animal entirely. That’s your eustachian tubes opening and closing to equalize pressure between your middle ear and throat. A rhythmic thumping or fluttering, almost like a butterfly wing inside your ear, points to tiny muscles in your middle ear contracting involuntarily. And a whooshing that pulses in time with your heartbeat suggests blood flow near your ear has become audible.
Each of these sounds has a distinct mechanism, and understanding which one matches your experience helps narrow down what’s going on.
How Your Brain Creates Phantom Sound
Most persistent tinnitus starts with some degree of damage to the cochlea, the spiral-shaped structure in your inner ear that converts sound waves into electrical signals. When hair cells in the cochlea are damaged by loud noise, aging, or other factors, they send fewer signals to the brain. Your brain doesn’t just accept the silence. It compensates.
Within about a week of cochlear damage, neurons in the early relay stations of your auditory pathway begin ramping up their activity. The normal balance between excitatory and inhibitory nerve signals shifts. Inhibition drops, and neurons start firing more rapidly and in bursts. Your brain is essentially turning up the gain on a quieter signal, amplifying its own internal “neural noise” in an attempt to restore normal input levels. You perceive that amplified neural activity as sound, even though no external sound exists.
This is why tinnitus so often accompanies hearing loss. The two are strongly linked: 10% of young adults experience tinnitus, rising to 24% of older adults as age-related hearing changes accumulate. About 2% of all adults have a severe, bothersome form.
Loud Noise Is the Most Common Trigger
Exposure to loud noise is the single most frequently cited trigger for tinnitus. A single concert, a day at a shooting range, or years of workplace noise can damage the delicate hair cells in your cochlea. That damage is usually permanent. Many people first notice ringing after a loud event and expect it to fade. Sometimes it does. Sometimes it doesn’t.
The threshold that matters is both volume and duration. Brief, extremely loud sounds (explosions, gunfire) can cause immediate damage. Prolonged moderate exposure, like wearing earbuds at high volume for hours daily, causes slower, cumulative harm. If you’ve noticed ringing after noise exposure that persists beyond a day or two, your cochlea has likely sustained some degree of injury.
Medications That Cause Ear Ringing
A long list of common medications can trigger tinnitus as a side effect. Some of the most familiar culprits are pain relievers you can buy over the counter: aspirin, ibuprofen, naproxen, and other anti-inflammatory drugs. The effect is often dose-dependent, meaning higher doses carry more risk, and in many cases the ringing resolves when you stop or reduce the medication.
Prescription medications linked to tinnitus include certain antibiotics (especially those in the aminoglycoside, macrolide, and quinolone families), some blood pressure drugs (including loop diuretics, beta blockers, and ACE inhibitors), anticonvulsants like carbamazepine, tricyclic antidepressants, SSRIs, and platinum-based chemotherapy drugs. If your ear noise started around the same time as a new medication or dose change, that connection is worth investigating.
Eustachian Tube Problems: Crackling and Popping
Your eustachian tubes are narrow passages connecting each middle ear to the back of your throat. They open briefly when you swallow, yawn, or chew to equalize air pressure and drain fluid. When these tubes don’t open and close properly, a condition called eustachian tube dysfunction, you may hear crackling, popping, or clicking sounds. Your ears might also feel full or plugged, like they need to “pop” but can’t.
Colds, allergies, sinus infections, and changes in altitude (flying, driving through mountains) are common triggers. The sounds themselves aren’t dangerous. They’re the physical result of air moving through a partially blocked or sticky tube. Yawning, swallowing, or gently blowing against pinched nostrils can sometimes help clear the blockage.
Muscle Spasms: Thumping and Fluttering
Two tiny muscles live inside your middle ear: the tensor tympani and the stapedius. They normally contract reflexively to dampen loud sounds and protect your inner ear. When either muscle spasms involuntarily, a condition called middle ear myoclonus, you hear it.
Tensor tympani spasms tend to produce clicking or thumping. Stapedius spasms often sound more like buzzing. Patients have also described the sensation as fluttering like a butterfly, bubbling, drum-like thumping, or a ticking sound. Because both muscles attach to the tiny bones that transmit vibration to your cochlea, their contractions directly stimulate your hearing apparatus. The episodes can last seconds or persist for hours, and they’re often irregular and unpredictable.
Pulsatile Tinnitus: Hearing Your Heartbeat
If the sound in your ear pulses in rhythm with your heart, you’re hearing blood flow. This is pulsatile tinnitus, and it has a fundamentally different cause from the ringing type. Rather than a phantom signal generated by your brain, pulsatile tinnitus involves a real, physical sound produced by blood moving through vessels near your ear.
Your carotid arteries pass through the bone surrounding your inner ear. Normally, you don’t hear them. But changes in blood flow, such as narrowed vessels, increased blood pressure, or abnormal vascular structures near the ear canal, can make that flow audible. A vascular loop entering the internal auditory canal is one recognized cause. Pulsatile tinnitus deserves medical attention because it can sometimes signal a treatable vascular condition, and imaging can usually identify or rule out a structural cause.
How Your Jaw and Neck Affect Ear Noise
If your tinnitus changes when you clench your jaw, turn your head, or tense your neck muscles, you likely have a somatic component to your tinnitus. This is more common than most people realize. In one study of tinnitus patients, 78% could change the loudness or pitch of their tinnitus by moving their head or neck.
Jaw clenching is the single most reliable trigger. Among people with somatic tinnitus, 90% reported that clenching their jaw made their tinnitus louder. For 41%, it doubled the loudness. For 26%, it tripled. About half also experienced a pitch change, with the pitch typically going up. Neck extension and shoulder rotation were also effective modulators.
The connection exists because nerves from your jaw (the trigeminal nerve) and upper neck (cervical nerves 1 and 2) share pathways with your auditory processing centers. Signals from these nerves can directly influence how your brain processes sound. This is why TMJ disorders, teeth grinding, neck tension, and poor posture can all worsen or even trigger tinnitus. For people in this category, treating the jaw or neck issue sometimes reduces the ear noise.
Red Flags Worth Taking Seriously
Most ear noises are benign, if annoying. But a few patterns warrant prompt medical evaluation. Sudden hearing loss in one ear, developing over three days or fewer, is considered an ear emergency. It may be accompanied by tinnitus, dizziness, or a feeling of fullness. Early treatment with steroids significantly improves the chance of recovery, so delays matter.
Tinnitus that appears only in one ear also deserves investigation. While it’s often harmless, one-sided ringing can occasionally be caused by an acoustic neuroma, a noncancerous tumor on the auditory nerve. These tumors are uncommon, but an MRI can rule them out, especially when no other cause is apparent.
Any sudden onset of tinnitus that doesn’t resolve within a few hours, especially if paired with hearing changes, ear pressure, or dizziness, is worth getting checked. The initial evaluation is straightforward: an examination of your ear canal, a hearing test, and a review of your medications and noise exposure history. Imaging is added when findings suggest a structural or vascular cause.
