Ringing in the ears is called tinnitus, and it affects roughly 27 million people in the United States, about 11% of the population. It’s the perception of sound when no external sound is actually present. You might hear ringing, buzzing, hissing, clicking, or even a roaring noise. For most people, it comes and goes. But about 41% of those with tinnitus experience it constantly.
Why Your Brain Creates Phantom Sound
Tinnitus isn’t actually generated by your ear. It starts in your brain. When the delicate hair cells in your inner ear become damaged (from loud noise, aging, or other causes), they stop sending certain sound signals to the brain. Your brain, expecting input that no longer arrives, compensates by cranking up its own activity in the affected frequency range. Neurons in the hearing centers begin firing spontaneously, and you perceive that activity as sound.
Animal studies show this clearly: after acoustic trauma, neurons tuned to the damaged frequency develop abnormally high spontaneous firing rates. That hyperactivity is what you hear as a phantom tone. The brain’s emotional processing centers also play a role. They evaluate how important or threatening a sound is, and when they flag tinnitus as something worth paying attention to, the signal gets amplified and becomes harder to ignore. This is why stress and anxiety often make tinnitus worse.
Common Causes
The most frequent trigger is noise exposure. Sounds above 85 decibels, roughly the volume of heavy traffic or a gas-powered lawn mower, cause progressive damage to the inner ear with repeated exposure. Permanent hearing loss can develop from noise exceeding 89 decibels for more than five hours a week. Among teenagers and young adults worldwide, about 1.1 billion are at risk for noise-induced hearing loss, largely from headphones and personal music players.
Age-related hearing loss is the other major driver. As hearing naturally declines with age, the brain’s compensatory hyperactivity can produce tinnitus even without a history of loud noise exposure. Smoking, diabetes, and low physical activity can all accelerate this process.
Certain medications can also trigger or worsen ear ringing. Aspirin is the most common culprit, especially at higher doses. Certain antibiotics used for serious infections (aminoglycosides like gentamicin and tobramycin), some chemotherapy drugs, and loop diuretics prescribed for fluid retention are all known to be toxic to the inner ear. If you notice ringing after starting a new medication, that’s worth flagging with your prescriber.
Less common causes include earwax blockage, jaw joint disorders, head or neck injuries, and conditions like Meniere’s disease that affect the inner ear’s fluid balance.
Pulsatile Tinnitus Is Different
If the sound you hear pulses in rhythm with your heartbeat, that’s a distinct condition called pulsatile tinnitus. Unlike regular tinnitus, this type usually has a physical, identifiable source. It’s caused by blood flow changes near your ear. The most common cause is narrowing of the veins that drain blood from the brain (venous sinus stenosis), which accounts for about 77% of vascular cases.
Pulsatile tinnitus can also result from abnormal connections between arteries and veins near the brain, called dural arteriovenous fistulas. These are the most concerning cause because they carry a risk of hemorrhage. Arterial narrowing or dissection in the neck can produce it too. Because the range of causes spans from benign turbulence to life-threatening vascular problems, pulsatile tinnitus always warrants a medical workup, typically with imaging.
When Ringing Signals Something Urgent
Most tinnitus is not dangerous. But certain patterns deserve prompt attention. Sudden hearing loss, defined as noticeable hearing decline in one ear over three days or fewer, is considered an ear emergency. It often comes with a feeling of ear fullness or pressure and tinnitus that doesn’t fade. Early treatment (ideally within the first two weeks) significantly improves the odds of recovering hearing.
Tinnitus that appears only in one ear also warrants evaluation, since unilateral symptoms can occasionally point to a growth on the hearing nerve. And any sudden onset of ringing that persists beyond a day or two should be checked out, even without hearing loss.
How Tinnitus Is Evaluated
A hearing test (audiogram) is the starting point. Since most tinnitus accompanies some degree of hearing loss, this test identifies which frequencies are affected and how severely. If your doctor wants to characterize the tinnitus itself, two additional techniques are commonly used.
In pitch matching, you listen to tones at different frequencies and identify which one sounds closest to your tinnitus. In loudness matching, an external sound is adjusted until it feels equal in volume to your tinnitus. These measurements help guide treatment. There’s also masking, where bands of noise are swept across the frequency spectrum to find what level of sound is needed to cover up the tinnitus, giving a practical measure of its strength.
Managing Tinnitus
There is no pill that cures tinnitus, but several approaches can meaningfully reduce how much it bothers you. The goal shifts from silencing the sound to retraining how your brain responds to it.
Sound therapy is the foundation. This can be as simple as a fan, white noise machine, or low-volume background music. The idea is to reduce the contrast between the tinnitus and your environment, making the phantom sound less noticeable. Many hearing aids now include built-in sound generators for this purpose, and since most people with tinnitus also have hearing loss, amplifying real-world sound through a hearing aid can itself reduce tinnitus perception.
Cognitive behavioral therapy adapted for tinnitus has strong evidence for reducing distress. It doesn’t change the volume of the sound, but it changes your emotional and psychological relationship to it, which for many people is what actually drives the suffering. Structured counseling helps break the cycle where noticing the tinnitus triggers anxiety, which makes you notice it more.
One newer option is bimodal neuromodulation. The FDA cleared a device called Lenire in 2023 that pairs sound stimulation through headphones with mild electrical stimulation on the tongue. In a clinical review of 212 patients with moderate or worse tinnitus, 91.5% experienced a clinically meaningful reduction in symptoms after about 12 weeks of treatment, with an average improvement of nearly 28 points on a standard tinnitus severity scale. No serious device-related side effects were reported. The treatment requires daily use at home, typically for 30 to 60 minutes per session.
Tinnitus retraining therapy, which combines structured counseling with low-level sound generators worn at least eight hours a day, has been used internationally for decades. However, a rigorous trial published in JAMA found no clinically meaningful difference in outcomes between the full protocol and standard care, raising questions about whether the elaborate structure adds benefit beyond basic sound enrichment and counseling alone.
What Helps Day to Day
Protecting your hearing prevents tinnitus from worsening. Earplugs at concerts, volume limits on headphones, and ear protection around power tools or machinery all matter. If you already have tinnitus, quiet rooms tend to make it more noticeable, so keeping some ambient sound in your environment, especially at bedtime, can make a significant difference in sleep quality.
Stress management also plays a direct role. Because the brain’s emotional circuits are involved in amplifying tinnitus signals, reducing overall stress through exercise, sleep hygiene, or relaxation techniques can lower the perceived volume. Many people with tinnitus report that their worst days coincide with their most stressful ones, and that connection is rooted in how the brain processes the signal, not imagination.
