Ringing in your ears, known as tinnitus, happens when your brain generates a sound that isn’t actually there. About 14% of adults worldwide experience it at some point, and roughly 1 in 10 live with it chronically. The ringing isn’t imaginary, but it is internal: your auditory system is producing a signal without any outside noise triggering it.
What’s Actually Happening Inside Your Ear
The most common trigger is damage to the tiny hair cells deep inside your inner ear. These cells convert sound vibrations into electrical signals your brain interprets as noise. When they’re damaged, whether from loud noise exposure, aging, certain medications, or injury, they send fewer signals to the brain than they used to.
Your brain doesn’t simply accept the silence. Instead, it turns up its own internal volume to compensate for the missing input. Neurons in multiple parts of your auditory system start firing more than they should, spontaneously generating activity that wasn’t prompted by any real sound. This hyperactivity is what you perceive as ringing, buzzing, hissing, or humming. It’s essentially your brain filling in a gap with phantom noise. The same process can also make you more sensitive to loud sounds, a condition called hyperacusis that often accompanies tinnitus.
Noise Damage and Age-Related Hearing Loss
Loud noise is the single most common cause of hair cell damage. A single concert, a blast of sound at close range, or years of working around heavy machinery can all do it. The hair cells don’t regenerate in humans, so the damage is permanent. Age-related hearing loss works through the same mechanism, just more gradually. As your ability to hear higher frequencies fades over time, the brain’s compensation response kicks in, and tinnitus often follows.
The overlap between hearing loss and tinnitus is substantial. In one clinical study, hearing aids reduced tinnitus severity in about 48% of patients, with the biggest improvements in how intrusive the sound felt and how much control people felt they had over it. That makes sense: when a hearing aid restores some of the missing sound input, the brain has less reason to amplify its own internal signals.
Medications That Trigger Ear Ringing
A surprisingly long list of common medications can cause tinnitus as a side effect. The categories include:
- Pain relievers: aspirin, ibuprofen, naproxen, and other anti-inflammatory drugs
- Antibiotics: certain types including aminoglycosides, some macrolides like azithromycin, and fluoroquinolones like ciprofloxacin
- Heart and blood pressure medications: loop diuretics, beta-blockers, ACE inhibitors, and calcium channel blockers
- Cancer drugs: platinum-based chemotherapy agents
- Antidepressants: some tricyclics and SSRIs
- Antimalarials: quinine and mefloquine
In many cases, the ringing stops when you discontinue the medication, though not always. If you notice ear ringing that started after beginning a new prescription, that connection is worth raising with whoever prescribed it. Don’t stop taking a medication on your own, but the timing can be an important clue.
Jaw Problems and the Ear Connection
Your jaw joint sits right next to your inner ear, and nerve pathways run directly from the jaw region toward the structures that process sound. When the temporomandibular joint (TMJ) is inflamed, misaligned, or under stress from clenching or grinding, those nerve signals can cross over into your auditory system. The brain’s sound-processing centers receive input from both your ears and your jaw, and when jaw-related signals become abnormally strong, they can trigger or worsen tinnitus.
A telling sign of jaw-related tinnitus is that you can change the pitch or volume of the ringing by moving your head or jaw. Sustained jaw clenching, common during periods of stress, can damage the joint’s internal disc and compress nearby nerves. If your ringing worsens during stressful periods or comes with jaw pain, clicking, or difficulty chewing, the TMJ connection is worth investigating.
Pulsatile Tinnitus: Ringing That Beats With Your Heart
If the sound you hear is rhythmic, thumping, or whooshing in sync with your pulse, you’re experiencing something distinct called pulsatile tinnitus. Unlike the more common type, this one has a physical sound source: blood flowing through vessels near your ear. You’re essentially hearing your own circulatory system.
Several conditions can cause it. High blood pressure pushes blood more forcefully through vessel walls. Anemia increases blood flow speed. Atherosclerosis creates turbulent flow through narrowed arteries. Hyperthyroidism speeds up the heart rate and increases circulation. Less commonly, abnormal tangles of blood vessels near the ear or increased pressure of fluid around the brain can be responsible. Pulsatile tinnitus deserves prompt medical attention because it can be the first sign of a vascular condition that needs treatment.
Warning Signs That Need Attention
Most tinnitus is a nuisance, not an emergency. But certain patterns suggest something more serious is happening. Ringing in only one ear is a red flag that warrants evaluation by an ear specialist, as it can point to conditions like a growth on the hearing nerve. Pulsatile tinnitus, as described above, also calls for further workup. Tinnitus accompanied by sudden hearing loss, dizziness, or pain should be evaluated quickly. Any abnormal findings when a doctor examines your ear canal with an otoscope also triggers a referral.
How Tinnitus Is Managed
There’s no pill that eliminates tinnitus. But the distress it causes, which is often the real problem, can be reduced significantly. Cognitive behavioral therapy (CBT) is the most studied approach, and multiple meta-analyses confirm it works. CBT doesn’t make the sound quieter. What it does is change how your brain reacts to the sound, reducing the annoyance, anxiety, and sleep disruption it causes. One Cochrane review found significant improvements in depression scores and quality of life, with effects that held up over time in many studies.
Tinnitus retraining therapy takes a different angle, using low-level background sound combined with counseling to help the brain gradually reclassify the ringing as unimportant, the way you stop noticing a ticking clock. Sound therapy on its own, whether from a white noise machine, a fan, or a dedicated app, helps many people by giving the brain competing input that makes the tinnitus less prominent.
A newer option reached the market in 2023: a bimodal neuromodulation device called Lenire, which received FDA approval for tinnitus treatment. It delivers mild electrical stimulation to the tongue while playing sounds through headphones, aiming to retrain the brain’s auditory processing. In a real-world study of 220 patients at a single clinic, about 78% experienced clinically meaningful improvement after six weeks of home use, rising to over 91% after twelve weeks. No serious device-related side effects were reported. The device requires a prescription and fitting by a clinician.
If hearing loss underlies your tinnitus, hearing aids can pull double duty, improving your hearing while simultaneously reducing the ringing by restoring the auditory input your brain has been compensating for. For many people, this is the most practical first step.
