Ringing in your ears is called tinnitus, and it affects roughly 11% of U.S. adults, about 27 million people. It happens when your brain generates a phantom sound (ringing, buzzing, hissing, or whooshing) without any external source. The cause can be as simple as earwax buildup or as significant as hearing damage, and understanding the difference helps you figure out what to do next.
What’s Actually Happening Inside Your Ear
Tinnitus isn’t your ear making noise. It’s your brain misinterpreting signals from your auditory system. When something disrupts the normal flow of sound information, whether at the level of the inner ear or higher up in the brain’s hearing centers, neurons start firing abnormally. Your brain reads that activity as sound, even though nothing external is producing it.
In many cases, the process starts with damage to the tiny hair cells in your inner ear. These cells convert sound waves into electrical signals. When some of them are damaged or destroyed, the brain loses input from certain frequencies and compensates by turning up its own internal volume. The auditory cortex and a relay station called the auditory thalamus play key roles in keeping this phantom sound going once it starts. Other brain networks involved in attention and emotion also get pulled in, which is why tinnitus can feel more intense when you’re stressed or anxious.
The Most Common Causes
Loud noise exposure is one of the top triggers. A concert, power tools, headphones at high volume, or a single explosive sound can all damage inner ear hair cells. After a loud event, ringing often fades within 16 to 48 hours, but even when the sound seems to disappear, there can be residual long-term damage to your hearing. If ringing persists beyond a couple of days after noise exposure, it may not fully resolve on its own.
Age-related hearing loss is another major cause. As you get older, the hair cells in your inner ear naturally deteriorate, and the brain’s compensation for that lost input often shows up as tinnitus. This is one reason ringing in the ears becomes more common in middle age and beyond.
Other frequent causes include:
- Earwax buildup pressing against the eardrum or blocking the ear canal
- Ear infections causing inflammation or fluid in the middle ear
- High blood pressure or high cholesterol, which can change blood flow near the ear
- Head and neck injuries that affect nerves connected to hearing
- Meniere’s disease, an inner ear disorder that also causes vertigo and hearing loss
Medications That Can Trigger Ringing
Certain drugs are known to be “ototoxic,” meaning they can harm hearing structures and trigger tinnitus. High doses of aspirin are a classic example. The ringing from aspirin typically fades once you lower the dose or stop taking it, but other medications can cause more lasting effects.
Drugs more likely to cause problems include certain antibiotics (like azithromycin and clarithromycin, especially at high doses over long periods), some chemotherapy drugs, and loop diuretics used for heart failure and kidney disease. Some newer biologic therapies can also affect hearing. If your ears started ringing after beginning a new medication, that connection is worth raising with whoever prescribed it.
When Your Jaw Is the Problem
The jaw joint sits right next to the structures of the inner ear, and they share muscles, ligaments, and nerve pathways. When the jaw joint isn’t functioning properly, that irritation can change how your brain processes sound, producing tinnitus. Clues that your jaw might be involved include persistent jaw pain or clicking, a feeling of fullness in the ear without signs of infection, and ringing that changes when you chew, clench, or yawn. Treating the jaw problem often improves the tinnitus.
Pulsatile Tinnitus: A Different Kind of Ringing
If the sound in your ear pulses in rhythm with your heartbeat, that’s called pulsatile tinnitus, and it has a different set of causes than the more common steady ringing. This type usually involves blood flow. You’re hearing turbulent blood moving through vessels near your ear. It often sounds like a lower-pitched whooshing rather than a high-pitched ring.
Pulsatile tinnitus can be caused by narrowing of the carotid artery, abnormalities in the veins that drain blood from the brain, or a condition called idiopathic intracranial hypertension (elevated pressure inside the skull, most common in younger women). Some of these causes carry a real risk of stroke or vision loss, which is why pulsatile tinnitus deserves prompt medical attention. A simple test: if pressing on the vein on one side of your neck changes the sound, that points toward a venous cause.
Signs That Need Medical Attention
Most tinnitus is not dangerous, but certain patterns are red flags. Ringing in only one ear, especially if it comes with gradual hearing loss on that side or balance problems, can indicate a benign growth on the nerve that connects the inner ear to the brain. These growths are slow-growing and treatable, but they need to be identified.
You should get evaluated if your tinnitus is one-sided, pulsatile, sudden in onset, or accompanied by hearing loss, dizziness, or neurological symptoms like facial weakness. Tinnitus that started after a head injury also warrants a workup.
What Helps and What Doesn’t
There is no pill that cures tinnitus. The most effective approaches focus on reducing how much the sound bothers you rather than eliminating it entirely.
Hearing aids are one of the most practical interventions for people whose tinnitus is linked to hearing loss. By amplifying external sounds, they give your brain more real input to work with, which can reduce the prominence of the phantom sound. Many modern hearing aids include built-in sound generators specifically for tinnitus.
Sound therapy, which uses background noise, nature sounds, or specially designed tones to “mask” the ringing, is widely recommended. However, a Cochrane review of six trials involving 553 participants found no significant change in tinnitus loudness or severity from sound therapy compared to other approaches like counseling or relaxation techniques. That doesn’t mean it’s useless for individuals. Many people find that having some background sound, even a fan or white noise machine, makes tinnitus far less noticeable, especially at bedtime.
Cognitive behavioral therapy (CBT) has the strongest evidence for reducing tinnitus distress. It doesn’t change the volume of the sound, but it changes your brain’s reaction to it. Over time, many people with tinnitus experience a process called habituation, where the brain gradually learns to filter out the phantom sound the way it filters out the hum of a refrigerator.
How Long It Typically Lasts
Temporary tinnitus from a loud noise, earwax, or an ear infection usually clears up once the trigger is gone. Post-concert ringing that fades within a day or two is common and not a sign of permanent damage in most cases, though repeated episodes suggest you’re pushing your ears past their limits.
Chronic tinnitus is a different story. Among people who report tinnitus, about 41% say they always have symptoms, and 28% have dealt with it for 15 years or more. But “chronic” doesn’t mean “unbearable.” Most people with long-term tinnitus find that it becomes less intrusive over time, particularly with the right combination of sound enrichment, stress management, and, when applicable, hearing correction.
