Ringing in your ears is almost always tinnitus, a phantom sound your brain generates when something disrupts normal hearing signals. About 14% of adults experience it at some point, and the odds rise with age: roughly 1 in 4 people over 65 report it. Most of the time it’s temporary and harmless, but persistent or one-sided ringing can signal something worth investigating.
What Tinnitus Actually Sounds Like
Tinnitus isn’t always a clean, high-pitched ring. People describe it as buzzing, hissing, roaring, clicking, or sounds resembling crickets, running water, or a distant engine. It can sit quietly in the background or drown out conversation. Some people notice it only in silence; others hear it over loud environments.
The vast majority of cases are “subjective,” meaning only you can hear the sound. In rare instances, a doctor can actually detect a sound coming from your ear canal using a stethoscope. That version, called objective tinnitus, usually points to a blood vessel issue or involuntary muscle contractions near the ear.
The Most Common Causes
Noise Exposure
This is the leading preventable cause. Sounds at or above 85 decibels (about the level of heavy city traffic or a gas-powered lawn mower) can damage your hearing with repeated exposure. The louder the sound, the less time it takes. A single loud concert, a few hours of power tools without ear protection, or years of listening to music at high volume through headphones can all trigger tinnitus that starts as temporary and becomes permanent.
What happens inside your ear: intense sound destroys or damages the tiny hair cells in the inner ear that convert vibrations into electrical signals. When those cells stop sending normal input to the brain, the auditory system compensates by turning up its own activity. That hyperactivity is what you perceive as ringing. Research has shown this “volume boost” in the brain can happen even when hair cells survive, if the nerve connections between them and the brain are severed, which explains why some people with normal hearing tests still develop tinnitus.
Age-Related Hearing Loss
The same nerve damage that happens from noise exposure also occurs gradually with aging. As hearing in certain frequency ranges declines, the brain fills in the gap with phantom sound. This is why tinnitus prevalence jumps from about 10% in young adults to nearly 24% in people 65 and older.
Earwax Buildup
Impacted earwax that fully blocks the ear canal can cause tinnitus along with muffled hearing and a feeling of fullness. The good news: symptoms typically resolve completely once the wax is cleared. If your ringing started suddenly and you feel pressure or blockage in one ear, this is one of the simplest explanations to rule out.
Medications
Several common drug classes can trigger ringing as a side effect. The most well-known culprits include high-dose aspirin, ibuprofen, naproxen, and other over-the-counter pain relievers. Certain antibiotics (particularly those in the aminoglycoside and quinolone families), some heart medications, and loop diuretics used for fluid retention can also cause it. In many cases the ringing fades after you stop the medication or lower the dose, but some drugs can cause permanent damage at high levels.
Jaw and Neck Issues
There’s a subtype called somatic tinnitus where the pitch or volume changes when you clench your jaw, turn your eyes, or press on certain spots on your head and neck. TMJ disorders, teeth grinding, and neck injuries are common triggers. If your ringing seems to shift with movement, this connection is worth exploring with a dentist or physical therapist.
Pulsatile Tinnitus: When the Sound Beats With Your Heart
If what you hear has a rhythmic, whooshing quality that matches your pulse, that’s pulsatile tinnitus, and it has a different set of causes. The most common is simply uncontrolled high blood pressure, which creates stronger blood flow near the ear that you can perceive as sound. Narrowing of the carotid arteries from plaque buildup is another frequent cause: turbulent blood flow through a partially blocked artery generates noise you hear on that side.
Less common vascular causes include abnormal tangles of blood vessels (arteriovenous malformations), small tumors near the ear called paragangliomas, and a condition called idiopathic intracranial hypertension where pressure around the brain rises for unclear reasons. Pulsatile tinnitus generally warrants a medical workup because it often has an identifiable, treatable cause.
When One-Sided Ringing Needs Attention
Tinnitus that occurs in only one ear deserves closer attention. One possible cause is an acoustic neuroma, a slow-growing, noncancerous tumor on the nerve connecting the inner ear to the brain. The typical signs include one-sided hearing loss (especially trouble understanding words), ringing in that same ear, and sometimes dizziness or facial numbness. These tumors are diagnosed with a contrast-enhanced MRI, which can pick up even small growths. Acoustic neuromas are uncommon, but unilateral tinnitus is the reason doctors will sometimes recommend imaging.
What Happens in Your Brain
Tinnitus is generated in the brain, not in the ear itself. When the inner ear sends weaker signals (from damage, aging, or blockage), the central auditory system tries to compensate by amplifying its own neural firing. Think of it like turning up the gain on a microphone: the system becomes more sensitive, but it also picks up static. This “maladaptive compensation” is why tinnitus often persists even after the original trigger is gone. The brain has essentially learned a new pattern of activity, and unlearning it takes time or intervention.
Treatments That Help
There’s no universal cure for tinnitus, but several approaches meaningfully reduce how much it bothers you.
Sound Therapy and Masking
Background sound (white noise machines, fans, ambient music, or purpose-built apps) makes tinnitus less noticeable by giving your brain competing input. Many people find that their tinnitus is most distressing in quiet environments, so consistent low-level sound at night can significantly improve sleep.
Tinnitus Retraining Therapy
TRT combines low-level sound generators with structured counseling to help your brain reclassify the tinnitus signal as unimportant. It’s a slow process: initial improvements typically appear around three months, with significant progress at six months and full habituation taking 12 to 18 months. Data from multiple treatment centers show that 74 to 84% of patients experience noticeable improvement.
Cognitive Behavioral Therapy
CBT doesn’t change the sound, but it changes your reaction to it. Because tinnitus distress is heavily influenced by anxiety and attention, breaking the cycle of “hear it, stress about it, focus on it more” can make the same volume of ringing far less intrusive.
Hearing Aids
If you have hearing loss alongside tinnitus, hearing aids can help both. By restoring the missing input your brain has been compensating for, they reduce the neural hyperactivity that drives the phantom sound. Many modern hearing aids include built-in tinnitus masking features.
Bimodal Neuromodulation
A newer approach uses a device that pairs sounds played through headphones with mild electrical stimulation of the tongue. The idea is to retrain the brain’s response to auditory signals. In a large clinical trial of one such device (Lenire), over 80% of participants saw reduced tinnitus severity during a 12-week treatment period, with benefits lasting up to 12 months afterward. The device is commercially available in Europe and has been cleared for use in some other markets.
What You Can Do Right Now
If your ears just started ringing after a loud event, give it 24 to 48 hours. Temporary tinnitus from a concert or noisy environment usually fades on its own. Protect your ears going forward: keep headphone volumes moderate and wear earplugs at concerts or around power tools. Anything under 70 decibels is safe even with long exposure.
If the ringing has persisted for more than a couple of weeks, especially if it’s in one ear, pulsing with your heartbeat, or accompanied by hearing loss or dizziness, get it evaluated. A hearing test is the standard first step and can reveal underlying hearing loss you may not have noticed. For pulsatile or one-sided tinnitus, imaging may be recommended to rule out vascular issues or growths.
Stress, caffeine, alcohol, and sleep deprivation don’t cause tinnitus directly, but they can amplify your awareness of it. Many people notice their ringing is louder during stressful periods or after poor sleep. Managing those factors won’t eliminate the sound, but it can make the difference between tinnitus that fades into the background and tinnitus that dominates your day.
