Your ears ring because your brain is generating a sound that isn’t actually there. This phantom perception, called tinnitus, affects roughly 1 in 5 adults. It happens when damage or changes in your inner ear cause your brain’s hearing centers to misfire, filling in the gaps with ringing, buzzing, hissing, or whooshing that only you can hear. The triggers range from everyday noise exposure to medications, jaw tension, and blood flow problems.
How Your Brain Creates a Sound That Isn’t There
The ringing starts with your inner ear but lives in your brain. Tiny hair cells deep inside your ear convert sound waves into electrical signals. When those cells are damaged, whether from loud noise, aging, or something else, they stop sending signals to the brain. Your auditory system doesn’t just go quiet, though. It compensates.
The nerve cells that lost their input stop being able to suppress signals from neighboring cells. Think of it like removing a fence between yards: activity from adjacent areas spills over. This creates abnormal bursts of rapid-fire neural activity in a narrow band of your hearing system, right at the boundary between the damaged zone and the healthy one. Your brain interprets that rogue electrical activity as sound. The pitch of your tinnitus typically matches the frequency range where your hearing is weakest, which is why people with high-frequency hearing loss often hear a high-pitched ring.
What makes tinnitus persistent is that it doesn’t stay confined to your hearing circuits. The abnormal signals trigger emotional and stress-response areas of the brain, which in turn amplify and sustain the phantom sound. That’s why tinnitus often feels worse when you’re anxious or exhausted. Your brain’s alarm system is feeding energy back into the loop.
The Most Common Triggers
Two causes dominate: noise exposure and age-related hearing loss. Repeated loud sound, from concerts, power tools, headphones at high volume, or industrial machinery, physically destroys the delicate hair cells in your inner ear. Those cells don’t regenerate. Even a single extremely loud event can trigger permanent ringing.
Age-related hearing loss, called presbycusis, is the other major driver. It generally begins around age 60 to 65 and worsens gradually. As hearing fades in certain frequency ranges, the brain’s compensation mechanism kicks in, and tinnitus often follows. Many people first notice ringing in a quiet room at night, when there’s no external sound to mask it.
Beyond these two, several other conditions can set off or worsen tinnitus:
- Earwax buildup or ear infections that block sound from reaching the inner ear
- Metabolic conditions like diabetes, thyroid disorders, anemia, and vitamin deficiencies
- Medications that are toxic to the inner ear (more on this below)
- Jaw and neck problems that feed abnormal nerve signals into your hearing pathways
Medications That Can Trigger Ringing
Certain drugs are known to damage hearing or cause tinnitus as a side effect. High-dose aspirin is one of the most well-known culprits. The ringing it causes is often reversible once you lower the dose, but not always. Common antibiotics like azithromycin and clarithromycin can cause it too, particularly at high doses over long courses. Loop diuretics prescribed for heart failure or kidney disease, certain chemotherapy drugs, and some newer biologic therapies also carry this risk.
If your ringing started or worsened after beginning a new medication, that connection is worth raising with your prescriber. In many cases, switching to an alternative can resolve the problem.
The Jaw and Neck Connection
If your tinnitus changes when you clench your jaw, turn your head, or press on your neck, you may have what’s called somatic tinnitus. The nerve that controls your jaw (the trigeminal nerve) sends branches directly into the same brainstem structure that processes sound. When your jaw joint is inflamed, your bite is misaligned, or you’re clenching under stress, those nerve signals can cross over into your auditory system and either create or intensify ringing.
People with jaw joint disorders are significantly more likely to report tinnitus that’s affected by stress and accompanied by neck pain. Sustained jaw clenching can damage the cartilage disc in the jaw joint, potentially compressing a nerve that runs near the ear. This is one of the more treatable forms of tinnitus because addressing the jaw problem, whether through a bite guard, physical therapy, or stress reduction, can reduce the ringing.
Pulsatile Tinnitus: When You Hear Your Heartbeat
If your ear ringing sounds rhythmic, like a whooshing or swooshing that matches your pulse, that’s a different condition called pulsatile tinnitus. Unlike the more common type, this one involves real sound generated by blood flowing through vessels near your ear. It’s not phantom. Something is making your blood flow louder or more turbulent than usual.
Common causes include high blood pressure, atherosclerosis (plaque narrowing your arteries), anemia that increases blood flow volume, hyperthyroidism speeding up your heart, and a condition where cerebrospinal fluid pressure builds around the brain. Pulsatile tinnitus can be the first sign of a serious vascular problem, so it warrants medical evaluation, especially if it starts suddenly or occurs on only one side.
When One-Sided Ringing Is a Red Flag
Tinnitus that affects only one ear, or is noticeably louder in one ear, deserves closer attention. One possible cause is a vestibular schwannoma, a slow-growing benign tumor on the nerve connecting your inner ear to your brain. Early signs include one-sided hearing loss, ringing in just that ear, and dizziness or balance problems. These tumors are uncommon but detectable with an MRI scan, and early detection matters for preserving hearing.
Tinnitus in both ears is far more typical and usually tied to the general causes above. The key distinction is asymmetry: if one ear rings significantly more than the other, or if your hearing drops on one side, that pattern is the one that warrants imaging.
What Helps Reduce the Ringing
There’s no pill that cures tinnitus, but several approaches can significantly reduce how much it bothers you. The most effective strategy depends on the underlying cause.
If you have hearing loss, hearing aids are often the single most helpful intervention. By amplifying the external sounds your ear is missing, they give your brain real input to process, which reduces its tendency to generate phantom sound. The masking effect is strongest when the hearing aid boosts frequencies in the same range as your tinnitus. Many modern hearing aids also include built-in white noise or ambient sound features specifically designed to cover tinnitus.
Sound therapy in general, even without hearing aids, provides relief for many people. White noise machines, fans, or nature sound apps can mask tinnitus enough to help you fall asleep or concentrate. These devices work only while they’re on, though. A more targeted option is notched-music therapy, where algorithmically modified sound emphasizes specific frequencies to retrain your brain’s response. Unlike white noise, notched-music devices tend to provide some lingering benefit after you stop using them.
Tinnitus retraining therapy combines educational counseling with low-level background sound over many months. The goal is habituation: training your brain to reclassify tinnitus as a neutral signal rather than a threat. In a randomized trial, about 71% of participants experienced meaningful improvement after 18 months. However, the same trial found that standard counseling-based care produced similar results, suggesting that structured support and understanding the condition may be as important as the specific protocol.
Dietary and Lifestyle Factors
High salt intake can alter the fluid balance in your inner ear by changing electrolyte concentrations in your blood. For people whose tinnitus is related to inner ear fluid disorders, reducing sodium may help control symptoms. Caffeine and alcohol, in high amounts, can constrict blood vessels and reduce blood supply to the inner ear, potentially making ringing worse. The effects vary from person to person. Some people notice a clear spike in tinnitus after coffee or alcohol, while others see no connection at all.
Stress and sleep deprivation reliably worsen tinnitus for most people, because they amplify the emotional brain circuits that sustain the phantom sound. Managing stress isn’t just general wellness advice here. It directly targets the mechanism that keeps tinnitus loud and distressing.
