A ringing sound in your ear with no external source is called tinnitus, and it affects roughly 11% of U.S. adults. It can sound like ringing, buzzing, hissing, whooshing, or clicking, and it ranges from a mild background noise to a sound loud enough to interfere with sleep and concentration. Most of the time, tinnitus is your brain’s response to some degree of hearing damage, but it can also signal other conditions worth paying attention to.
Why Your Brain Creates a Sound That Isn’t There
Your inner ear contains thousands of microscopic hair cells that convert sound waves into electrical signals for the brain. When those hair cells are damaged, whether from loud noise, aging, or injury, they can misfire and send false signals along the auditory nerve. Your brain interprets those signals as sound, even though nothing external is producing it.
The damage can happen at several levels. The hair cells themselves can stiffen or break. The connections between hair cells and nerve fibers can deteriorate. Or the membrane that sits over those cells can shift position and press against them, triggering continuous electrical activity. Once the brain starts receiving these abnormal signals, it can also amplify them, which is why tinnitus sometimes persists or worsens over time even after the original trigger is gone. In many cases, the brain essentially “turns up the volume” to compensate for reduced input from a damaged ear.
The Most Common Causes
About 90% of people with tinnitus also have some degree of hearing loss. That hearing loss is often the root cause. It can come from aging, a single blast of loud noise, or years of cumulative exposure. The CDC considers any repeated noise exposure at or above 85 decibels hazardous, which is roughly the volume of heavy city traffic or a gas-powered lawn mower. For every 3-decibel increase above that threshold, the safe exposure time drops significantly.
But hearing loss isn’t the only trigger. Other common causes include:
- Earwax buildup or ear infections that block the ear canal and change how sound reaches the inner ear
- Jaw (TMJ) problems, because the chewing muscles sit close to the middle ear, and a ligament from the jaw connects directly to one of the tiny hearing bones
- Neck injuries or tension, since nerve endings in the cervical spine connect to hearing centers in the brain
- Certain medications, including high-dose aspirin, some antibiotics prescribed at high doses for long periods, loop diuretics used for heart failure, and certain chemotherapy drugs
- Abnormal bone growth in the middle ear, a hereditary condition that stiffens the bones responsible for transmitting sound
- Circulatory problems that change blood flow near the ear
Some people with TMJ issues or neck problems can actually change the pitch or volume of their tinnitus by moving their jaw, clenching their teeth, or turning their head. This is called somatosensory tinnitus, and it’s a strong clue that the source is musculoskeletal rather than the inner ear itself.
What the Sound Tells You
The type of sound you hear matters. Most tinnitus is “subjective,” meaning only you can hear it. This is the most common form and is tied to hearing loss or nerve activity in the brain. It sounds like a steady ringing, buzzing, or hissing and tends to be present in both ears, though not always.
A less common type is “objective” tinnitus, where the sound is actually being produced inside your body and can sometimes be heard by a doctor with a stethoscope. This is usually related to blood vessel abnormalities or muscle spasms near the ear.
Pulsatile tinnitus is a specific pattern worth knowing about. It pulses in rhythm with your heartbeat and feels like a whooshing or thumping. Most cases turn out to be harmless venous hums (the sound of blood flowing through veins near the ear), but pulsatile tinnitus can also point to narrowed arteries, abnormal blood vessel connections, or tumors near the ear. It always warrants medical evaluation.
When Ringing Ears Need Attention
Occasional, brief ringing after a loud concert or a long flight is common and usually resolves on its own. Persistent tinnitus that lasts more than a few days, or that comes on suddenly, deserves a closer look. A few specific patterns are considered red flags:
- Ringing in only one ear can be a sign of a benign tumor on the hearing nerve (vestibular schwannoma) or Ménière’s disease, and typically calls for a hearing test and possibly an MRI
- Sudden pulsatile tinnitus, especially with dizziness or facial weakness, may indicate a serious vascular or neurological problem
- Tinnitus paired with sudden hearing loss is treated as an urgent condition because early intervention improves outcomes
- Ear pain, drainage, or persistent foul odor alongside tinnitus suggests an infection or structural problem that needs treatment
How Tinnitus Affects Daily Life
For many people, tinnitus is a minor nuisance that fades into the background. But for a significant number, it becomes a serious quality-of-life issue. A large meta-analysis found that people with tinnitus are roughly twice as likely to experience depression and about 1.6 times as likely to develop anxiety compared to those without it. The strongest link was with insomnia: people with tinnitus were three times more likely to have significant sleep problems.
This makes sense when you consider that tinnitus is often loudest in quiet environments, exactly when you’re trying to fall asleep. The frustration of a sound you can’t escape creates a feedback loop where stress makes the tinnitus more noticeable, and the tinnitus creates more stress. Among people with chronic tinnitus, about 41% report having symptoms constantly, and nearly 28% have dealt with them for 15 years or more.
What Actually Helps
There is no pill or procedure that reliably eliminates tinnitus. Treatment focuses on reducing how much the sound bothers you and how much it interferes with your life. The good news: a Johns Hopkins clinical trial found that roughly half of participants experienced meaningful improvement over 18 months regardless of the specific treatment approach used.
The most common strategies include sound therapy, where you use background noise, white noise machines, or hearing aids to make tinnitus less prominent. If you have hearing loss, hearing aids alone can significantly reduce tinnitus by restoring the missing input your brain has been trying to compensate for. Cognitive behavioral therapy helps by changing the emotional and attentional response to the sound rather than trying to eliminate it.
Tinnitus Retraining Therapy (TRT) combines low-level background sound with counseling to help your brain reclassify tinnitus as a neutral signal. The Johns Hopkins trial found that TRT didn’t outperform standard counseling and sound therapy, but all approaches produced real improvement. The takeaway is that structured treatment of any kind tends to help over time.
If your tinnitus is caused by something specific and treatable, like earwax blockage, a jaw disorder, medication side effects, or an ear infection, addressing that underlying cause can reduce or resolve the ringing entirely. For tinnitus linked to TMJ problems, dental treatment or physical therapy targeting the jaw and neck muscles often makes a noticeable difference.
Protecting Your Ears Going Forward
Since noise exposure is the single most preventable cause of tinnitus, protecting your hearing is the most effective thing you can do. Wear earplugs at concerts, while using power tools, or in any environment where you need to raise your voice to be heard. Keep headphone volume below 60% of maximum. If you work in a noisy environment, the CDC recommends limiting exposure to 85 decibels over an eight-hour shift, and cutting that time in half for every 3-decibel increase above that level.
If you already have tinnitus, avoiding further noise damage helps prevent it from worsening. Many people find that caffeine, alcohol, or high sodium intake temporarily increases their tinnitus, though this varies widely from person to person. Tracking your own triggers can help you manage flare-ups.
