Ringing in your ears, known medically as tinnitus, is your brain perceiving sound when no external sound is present. It affects more than 740 million adults worldwide, and while it’s usually harmless and temporary, it can sometimes signal an underlying condition worth addressing. The sound might be a high-pitched ring, a buzz, a hiss, or even a whooshing rhythm that matches your heartbeat.
Why Your Brain Creates the Sound
Most ear ringing happens because of changes in how your auditory system processes signals. Tiny hair cells inside your inner ear convert sound waves into electrical signals that travel to your brain. When those hair cells are damaged or irritated, they can misfire, sending signals your brain interprets as sound even though nothing external caused it. Your brain essentially “fills in” the missing input, producing a phantom tone.
This type of ringing is called subjective tinnitus, meaning only you can hear it. It accounts for the vast majority of cases. In rare instances, there’s an actual physical sound being generated inside your body, often from blood flowing through vessels near your ear, that a doctor can also detect. That’s called objective tinnitus, and it has different causes and implications.
The Most Common Triggers
Loud noise exposure is the single most frequent cause. A concert, power tools, headphones at high volume, or a sudden blast can all damage those inner ear hair cells. Sometimes the ringing fades within hours or days. Other times, especially with repeated exposure, the damage becomes permanent and the ringing stays.
Age-related hearing loss is the other major driver. About 1 in 12 adults between ages 48 and 92 experience tinnitus, and the prevalence climbs with age, particularly after 65. As hearing naturally declines, the brain compensates by amplifying its own internal signals, which can produce a constant background tone.
Beyond noise and aging, several other things can trigger or worsen ringing:
- Earwax buildup pressing against the eardrum
- Ear infections or sinus congestion causing pressure changes
- Stress and fatigue, which heighten the brain’s sensitivity to internal signals
- Jaw problems (TMJ disorders), where dysfunction in the jaw joint affects nearby hearing structures
- Neck tension, where nerve endings in the cervical spine connect to hearing centers in the brain
- Caffeine and alcohol in large amounts
Medications That Cause Ear Ringing
A surprisingly long list of common medications can trigger tinnitus as a side effect. High-dose aspirin is one of the most well-known culprits. Other medications that may affect hearing include certain antibiotics (particularly a class used for serious infections that can permanently damage inner ear cells), loop diuretics used for heart failure and kidney disease, and some long-term antibiotic prescriptions at high doses.
The ringing from medications is often temporary and resolves after the dose is lowered or the drug is stopped. But in some cases, particularly with certain antibiotics given intravenously, the hearing damage and tinnitus can be permanent. If you notice ringing shortly after starting a new medication, that’s worth flagging with whoever prescribed it.
Pulsatile Tinnitus: When It Beats With Your Heart
If the sound in your ear pulses in rhythm with your heartbeat, that’s a distinct type called pulsatile tinnitus. It usually has a physical, identifiable cause related to blood flow. The most common sources are abnormalities in the carotid artery (the major artery running through your neck) or the jugular vein system near your ear.
Atherosclerosis, where fatty deposits narrow blood vessels, can create turbulent flow that you hear as a rhythmic whooshing. High blood pressure is another common contributor. Less frequently, pulsatile tinnitus comes from a condition called benign intracranial hypertension, where pressure inside the skull increases without an obvious cause. Abnormal connections between arteries and veins near the ear, though uncommon, are another possibility. Pulsatile tinnitus is more likely to have a treatable underlying cause than standard ringing, so it’s worth getting checked out.
How Jaw and Neck Problems Play a Role
Your jaw joint sits remarkably close to your ear canal, and the two share nerve pathways and even a ligament connection to one of the tiny bones in your middle ear. When the jaw joint is inflamed, misaligned, or strained, it can directly influence hearing structures and trigger or intensify tinnitus. Some people with jaw problems can actually change the volume or pitch of their tinnitus by moving their jaw, clenching, or turning their neck. This is called somatosensory tinnitus.
Chronic neck pain and tension work through a similar mechanism. Nerve endings in the cervical spine connect to hearing-processing areas of the brain, so persistent neck problems can aggravate tinnitus even when there’s nothing wrong with the ears themselves.
Red Flags That Need Quick Attention
Most ear ringing is benign, but certain patterns warrant urgency. Sudden hearing loss in one ear, especially when accompanied by ringing, a feeling of fullness, or dizziness, is considered a medical emergency. This condition, called sudden sensorineural hearing loss, can strike without warning. About half of people recover some or all of their hearing spontaneously within one to two weeks, but treatment started within the first two to four weeks dramatically improves outcomes. Waiting longer significantly reduces the chance of recovery.
Ringing in only one ear that doesn’t go away also deserves investigation, since it can occasionally point to a growth on the hearing nerve. And any tinnitus accompanied by facial weakness, severe vertigo, or personality changes should be evaluated promptly.
How Persistent Tinnitus Is Managed
When ringing sticks around, the goal shifts from curing it to reducing how much it bothers you. The most effective approach is called tinnitus retraining therapy, which combines low-level background sound with structured counseling sessions. The idea is to retrain your brain’s reaction to the tinnitus signal so it gradually fades into the background, much like how you stop noticing the hum of a refrigerator. In one study, tinnitus completely disappeared in about 60% of patients who completed the therapy, and roughly 86% experienced meaningful improvement.
Sound masking is a simpler version of the same principle. White noise machines, fan sounds, or specialized ear-level devices add background noise that reduces the contrast between the tinnitus signal and silence, making the ringing less noticeable. Many people find this especially helpful at night, when a quiet room makes tinnitus louder by comparison.
If an underlying cause is identified, treating it often helps. Removing impacted earwax, managing blood pressure, switching medications, or addressing a jaw disorder can reduce or eliminate the ringing entirely. For the roughly 120 million people worldwide who experience tinnitus as a major ongoing problem, a combination of sound therapy, stress management, and treating any contributing conditions typically offers the most relief.
