Ear ringing, known clinically as tinnitus, happens when your brain perceives sound that isn’t coming from the outside world. About 27 million Americans experience it, roughly 11% of the adult population. In most cases, the cause traces back to some form of hearing damage, but the full list of triggers is longer and more varied than most people realize.
Hearing Damage Is the Most Common Cause
Ninety percent of people with tinnitus also have measurable hearing loss. The connection comes down to tiny hair cells lining your inner ear (the cochlea). These microscopic structures convert sound vibrations into electrical signals your brain interprets as noise. When they’re bent or broken, whether from a single loud blast or years of moderate noise exposure, they can leak random electrical impulses to your brain. Your brain reads those stray signals as sound, and the result is ringing, buzzing, hissing, or humming that only you can hear.
Two main forces damage those hair cells. The first is noise. Heavy equipment, firearms, chainsaws, concerts, and even earbuds played at high volume over long periods all take a toll. Factory workers, construction crews, musicians, and military personnel face especially high risk. The second is age. Hair cells degrade naturally over time, which is why tinnitus becomes more common in your 50s and beyond. In many people, both factors overlap.
The damage is usually permanent. Hair cells in humans don’t regenerate, so once they’re lost, the hearing gap they leave behind can produce a persistent ringing that lasts years. Among Americans with tinnitus, about 28% have had symptoms for 15 years or longer, and roughly 41% say the sound is always present.
Your Jaw and Neck Can Create Ringing Too
Not all tinnitus starts in the ear. Your jaw joint sits right next to your cochlea, and nerve connections run directly from the jaw region into the hearing structures of your brainstem. When the temporomandibular joint (TMJ) is inflamed, misaligned, or under chronic stress, it can feed abnormal signals into the part of your brainstem that processes sound. Those extra signals mix with normal auditory input and produce a phantom ringing.
People with jaw-related tinnitus tend to look different from the typical profile. They’re more likely to be younger, more likely to be female, and they can often change the pitch or volume of their ringing by moving their head or jaw. Neck pain and stress are also closely linked to this type. If you notice that clenching your teeth, chewing, or turning your head shifts your tinnitus, your jaw or neck muscles are likely involved.
Medications That Trigger Ringing
Certain drugs are directly toxic to the inner ear. Some cause temporary ringing that resolves when you stop taking them, while others can cause lasting damage.
- Temporary triggers: Aspirin (especially at high doses), quinine used for malaria treatment, and loop diuretics prescribed for heart or kidney conditions. The ringing from these typically fades once the medication is reduced or stopped.
- Permanent triggers: Certain aminoglycoside antibiotics like gentamicin, and platinum-based chemotherapy drugs like cisplatin and carboplatin. These can destroy inner ear hair cells outright. If you have a family history of hearing sensitivity, your risk from aminoglycosides is higher.
Pulsatile Tinnitus: When the Sound Matches Your Heartbeat
If your ear ringing pulses in rhythm with your heartbeat, that’s a distinct condition called pulsatile tinnitus, and it has different causes. Instead of originating from damaged hair cells, it usually reflects turbulent blood flow near the ear.
The most common cause is narrowing (atherosclerosis) of the carotid arteries, the major blood vessels running through your neck. When plaque builds up and narrows those arteries, blood flow becomes turbulent, and the ear picks up that turbulence as a rhythmic whooshing or thumping. Less commonly, a type of benign tumor called a paraganglioma (or glomus tumor) near the jugular vein or middle ear can produce the same effect. In some cases, a doctor can actually hear your pulsatile tinnitus by listening to your neck or ear with a stethoscope, which makes it “objective” tinnitus rather than purely subjective.
Pulsatile tinnitus deserves prompt evaluation because it points to a specific vascular cause that may need treatment on its own terms.
What’s Happening in Your Brain
Tinnitus isn’t just an ear problem. Research in neuroscience has shown that when the ear stops sending certain frequencies to the brain (because of hair cell damage), the brain’s auditory processing areas reorganize themselves. Think of it like a map being redrawn: the brain regions that used to handle the missing frequencies don’t just go quiet. Instead, they become hyperactive, amplifying signals from neighboring frequency zones or generating their own activity. This is similar to phantom limb pain, where the brain continues to “feel” a limb that’s no longer there.
This reorganization helps explain why tinnitus persists even when the original ear damage happened long ago. The ringing has become embedded in how your brain processes sound. It also explains why stress, fatigue, and lack of sleep can make tinnitus worse: they increase overall neural activity, which amplifies the phantom signal.
How Tinnitus Is Evaluated
An audiologist evaluating tinnitus will start with a detailed hearing test and a thorough history covering when the ringing started, how it’s progressed, where you perceive it, and what makes it better or worse. From there, they’ll typically run a set of specialized measurements: matching the pitch and loudness of your tinnitus, testing how much external sound is needed to mask it, and checking your tolerance for loud sounds. Standardized questionnaires help gauge how much the tinnitus affects your sleep, concentration, mood, and daily functioning.
Tinnitus that appears in only one ear, comes on suddenly, or arrives alongside dizziness or rapid hearing loss warrants closer attention. These patterns can signal conditions like a benign growth on the hearing nerve (acoustic neuroma) or sudden sensorineural hearing loss, both of which benefit from early intervention.
Managing the Ringing
There’s no pill that eliminates tinnitus, but several approaches can reduce how much it bothers you. The most established is tinnitus retraining therapy (TRT), which combines low-level background sound with counseling designed to help your brain reclassify the ringing as unimportant. In one clinical study of 57 patients, tinnitus completely disappeared in about 60% after treatment, and overall improvement was seen in 86%. Results are typically evaluated after about three months.
Cognitive behavioral therapy (CBT) takes a different angle, focusing on the emotional and psychological response to tinnitus rather than the sound itself. It won’t make the ringing quieter, but it can significantly reduce the distress, sleep disruption, and anxiety that tinnitus creates. For many people, that shift in reaction is what makes the difference between tinnitus being a minor background nuisance and a life-altering problem.
Sound therapy on its own, whether through hearing aids, white noise machines, or smartphone apps, helps by giving the brain competing input so it pays less attention to the internal ringing. If hearing loss is part of the picture, properly fitted hearing aids often reduce tinnitus as a side benefit, simply by restoring the frequencies your brain has been missing. For jaw-related tinnitus, treating the underlying TMJ dysfunction through a dentist or physical therapist can reduce or resolve the sound entirely.
