Ringing in your ears is almost always tinnitus, a perception of sound when no external sound is present. About 10% of adults experience it chronically, and it’s rarely a sign of something dangerous. Most of the time, it signals that something has changed in how your auditory system processes sound, whether from noise exposure, age-related hearing shifts, earwax buildup, or medication use.
What’s Actually Happening in Your Brain
The ringing you hear isn’t being produced by your ear itself. In most cases, tinnitus originates in the brain. When the inner ear is damaged or its input changes (from noise exposure, aging, or other causes), the brain loses some of the sound signals it’s used to receiving. To compensate, it turns up its own internal volume, amplifying the activity of nerve cells in the hearing centers. That amplified neural firing, happening with no actual sound coming in, gets interpreted as a tone, hiss, or buzz.
This is why tinnitus so often accompanies hearing loss. The brain is essentially filling in a gap, but doing so in a way that produces a phantom sound. People describe it as sounding like crickets, running water, escaping steam, a high-pitched tone, or a low hum. The specific sound varies from person to person.
The Most Common Causes
Noise exposure is one of the leading triggers. A single loud concert, years of working around machinery, or regular use of earbuds at high volume can all damage the delicate hair cells in the inner ear. Once those cells are harmed, they don’t regenerate. Tinnitus is the most common service-related disability among military veterans for exactly this reason.
Age-related hearing loss is the other big contributor. Tinnitus prevalence climbs steadily with age: roughly 10% of young adults report it, 14% of middle-aged adults, and nearly 24% of older adults.
Beyond noise and aging, several other triggers are well documented:
- Earwax or ear infections. A blocked ear canal can change how sound reaches your eardrum, triggering ringing that often resolves once the blockage clears.
- Medications. Common over-the-counter painkillers like aspirin, ibuprofen, and naproxen can cause tinnitus, especially at higher doses. Certain antibiotics, antidepressants, blood pressure medications, and chemotherapy drugs are also known triggers.
- Head or neck injuries. Trauma can damage the structures of the ear or the nerve pathways that carry sound signals to the brain.
- Jaw problems. The jaw joint sits very close to the ear. Clenching, grinding, or misalignment can irritate surrounding tissue enough to cause or worsen ringing.
- Chronic conditions. Diabetes, thyroid disorders, migraines, anemia, and autoimmune conditions like lupus have all been linked to tinnitus.
Pulsatile Tinnitus Is Different
If your ear ringing sounds rhythmic, like a whooshing or thumping that matches your heartbeat, that’s pulsatile tinnitus. This type has a distinct cause: you’re hearing turbulent blood flow through vessels in your head or neck. It can result from high blood pressure, narrowed arteries, or abnormalities in the veins near your ear such as irregularities of the jugular bulb or sigmoid sinus. Unlike the more common form, pulsatile tinnitus often has a treatable structural cause, so it warrants a medical evaluation.
When Ear Ringing Needs Attention
Most tinnitus is benign and doesn’t signal a medical emergency. But certain patterns are red flags. Ringing that starts suddenly in one ear only can sometimes indicate a growth on the hearing nerve (a benign tumor called an acoustic neuroma) and should be checked. Tinnitus paired with sudden hearing loss that develops over 72 hours is considered an ear emergency, because early treatment with steroids can sometimes restore hearing.
Ringing that begins after a head injury could point to a skull fracture and needs immediate evaluation. Sudden-onset pulsatile tinnitus also requires prompt assessment to rule out vascular problems. And tinnitus alongside acute vertigo or neurological symptoms like facial weakness or slurred speech raises concern for stroke.
Ringing that’s present in both ears, came on gradually, and isn’t accompanied by hearing loss or other symptoms is far less concerning. It typically doesn’t require specialist referral.
How Doctors Evaluate Tinnitus
If your ringing does need investigation, the process usually starts with an ear exam to check for wax buildup, infection, or visible abnormalities, followed by a hearing test (audiogram) to measure whether there’s underlying hearing loss and what frequencies are affected. These two steps alone often reveal the cause. If pulsatile tinnitus or one-sided ringing is present, imaging comes next. CT scans are typically used when a structural issue in the inner ear is suspected, while MRI is better at detecting soft-tissue problems like nerve tumors or blood vessel abnormalities.
Managing the Ringing
There’s no universal cure for tinnitus, but several approaches can significantly reduce how much it bothers you. The most studied is cognitive behavioral therapy, which doesn’t make the sound quieter but changes your brain’s emotional and attentional response to it. Multiple meta-analyses have found CBT produces moderate to strong reductions in tinnitus-related distress, with improvements in mood and quality of life that hold over time.
Sound therapy is another common strategy. This can be as simple as playing background noise, nature sounds, or music to reduce the contrast between the tinnitus and silence, which is when ringing tends to feel loudest. Many people notice their tinnitus most at bedtime, and a white noise machine or fan can make a real difference. Hearing aids also help many people: by restoring the sound input the brain has been missing, they can reduce the neural overactivity that generates the phantom ringing in the first place.
If a specific cause is identified, treating it often resolves the tinnitus. Removing impacted earwax, switching a medication, treating an ear infection, or addressing a jaw problem can eliminate ringing entirely in those cases.
Diet and Lifestyle Factors
You may have heard that caffeine, alcohol, or salt can worsen tinnitus. The evidence is mixed and the effects are small. In a large survey of tinnitus patients, caffeine worsened symptoms for about 16% of people, alcohol for about 13%, and salt for about 10%. For the vast majority, these substances made no noticeable difference. Interestingly, some research suggests that regular caffeine intake may actually lower the risk of developing tinnitus in the first place, though people who already have it may benefit from cutting back. The takeaway: pay attention to your own patterns rather than following blanket dietary rules.
Stress and sleep deprivation are more consistent aggravators. Tinnitus and stress feed each other in a loop: the ringing causes anxiety, and anxiety makes the ringing more noticeable. Breaking that cycle through better sleep, exercise, and stress management often brings more relief than any dietary change.
