Constant ringing in the ears is called tinnitus (pronounced “TIN-ih-tus” or “tin-EYE-tus”). It affects millions of people and can sound like ringing, buzzing, hissing, humming, or whistling. The sound isn’t coming from the outside world. It’s generated internally, and in most cases, only you can hear it.
Two Types of Tinnitus
Most people with tinnitus have what’s known as subjective tinnitus, meaning they’re the only one who can hear the sound. This is by far the more common type and can range from a faint background tone to a loud, persistent ringing that interferes with concentration and sleep.
A less common form, objective tinnitus, produces a sound that a doctor can actually detect during an exam using a stethoscope or sensitive microphone. It’s typically caused by something mechanical happening near the ear, like blood vessel abnormalities or involuntary muscle contractions. It’s not loud enough for someone across the room to notice, but it has a physical source that can often be identified and treated.
Why the Brain Creates Phantom Sound
Tinnitus is a phantom sound perception, meaning the brain generates it without any external noise. In most cases, it starts with some degree of hearing loss, whether from aging, noise damage, or another cause. When the inner ear stops sending certain sound signals to the brain, the auditory system compensates by becoming hyperactive. Through a process that researchers still don’t fully understand, these internally generated signals get released into conscious awareness and become the persistent ringing or buzzing you perceive.
This is why tinnitus and hearing loss are so closely linked, though not everyone with hearing loss develops tinnitus. The phantom sound seems to require both the loss of input and specific changes in brain networks involved in hearing and attention.
Common Causes and Triggers
Noise exposure is one of the leading causes. A single loud concert, years of working around heavy machinery, or repeated exposure to gunfire can all trigger it. Tinnitus is the most common service-related disability among military veterans for exactly this reason.
Other well-established causes include:
- Age-related hearing loss. Gradual decline in hearing naturally increases tinnitus risk.
- Medications. High-dose aspirin, certain antibiotics (like azithromycin and clarithromycin taken long-term at high doses), chemotherapy drugs, and loop diuretics used for heart failure or kidney disease can all damage hearing structures or trigger ringing.
- Earwax buildup or ear infections. A blocked ear canal can create or worsen the sensation.
- Head or neck injuries. Trauma can damage the ear itself, the nerve that carries sound to the brain, or the brain regions that process sound.
- Jaw problems. Clenching, grinding, or joint dysfunction in the jaw can contribute because of how close the jaw joint sits to the ear.
Less common triggers include Ménière’s disease (an inner ear disorder that also causes vertigo), benign tumors on the hearing nerve, and chronic conditions like diabetes, thyroid disorders, and certain autoimmune diseases.
Pulsatile Tinnitus: The Rhythmic Version
Some people hear a rhythmic whooshing or thumping that beats in time with their pulse. This is called pulsatile tinnitus, and it’s different from the steady ringing most people describe. It usually has a vascular cause, meaning something about blood flow near the ear is creating an audible sound.
On the venous side, causes include increased pressure inside the skull, narrowing of the large veins that drain the brain, or abnormalities in the bony wall separating the ear from a major vein. Arterial causes include narrowing of the carotid artery, abnormal connections between arteries and veins near the brain, or structural irregularities in blood vessels close to the ear. Because pulsatile tinnitus often has an identifiable and treatable physical source, it generally warrants a thorough workup with imaging.
The Mental Health Connection
Tinnitus isn’t just an auditory problem. Living with a constant sound you can’t escape takes a real psychological toll. Studies consistently find high rates of anxiety and depression among people with chronic tinnitus. Anxiety affects roughly 26 to 49% of tinnitus patients depending on the study, and depression shows up in about 25 to 33%. One study found that 77% of tinnitus patients met criteria for some form of psychiatric disorder.
Sleep is another major casualty. People with tinnitus consistently report fewer hours of sleep than those without it. The quiet of nighttime makes the ringing more noticeable, which increases stress, which in turn can make the tinnitus louder. This feedback loop is one of the most frustrating aspects of the condition and a key reason treatment often targets the emotional response alongside the sound itself.
How Tinnitus Is Measured
There’s no blood test or scan that can detect tinnitus directly, so diagnosis relies on a hearing evaluation and specialized matching tests. An audiologist will typically start with a standard hearing test to check for underlying hearing loss. From there, more specific measurements can pin down the characteristics of your tinnitus.
Sound matching involves playing different tones and layering sounds until you identify one that closely matches what you hear. This creates a baseline your audiologist can use to customize treatment. They’ll also measure your minimum masking level, which is the volume of external noise needed to cover up your tinnitus. This gives a practical sense of how loud the ringing feels to you. A loudness discomfort test checks whether you have heightened sensitivity to external sound, which is common with tinnitus and affects which treatments are appropriate.
Treatment Options
There’s no universal cure for tinnitus, but several approaches can significantly reduce how much it bothers you. The most established is tinnitus retraining therapy, which combines counseling with the use of low-level sound generators worn in or near the ear. The goal is habituation: training your brain to reclassify the tinnitus signal as unimportant background noise rather than a threat. Multiple independent clinics have reported success rates around 80% or higher, with meaningful improvement typically appearing after about three months and the full process taking 12 to 18 months. Notably, counseling alone produces much lower success rates (around 18% in one study), while combining it with sound generators pushes effectiveness up to about 83%.
Hearing aids help roughly 70% of tinnitus patients who also have hearing loss. By restoring the missing sounds that triggered the brain’s overcompensation in the first place, hearing aids can reduce the phantom signal substantially.
A newer option is bimodal neuromodulation, which pairs sound therapy with mild electrical stimulation on the tongue. The Lenire device, which uses this approach, received FDA authorization in 2023 for people with moderate or worse tinnitus. In its pivotal trial of 112 participants, it outperformed sound therapy alone for those with moderate-to-severe symptoms. The treatment involves up to 60 minutes of daily use at home, with follow-ups at 6 and 12 weeks. It’s not a fit for everyone, but it represents a meaningful new option for people who haven’t responded well to other approaches.
Sound masking, cognitive behavioral therapy for managing the emotional response, and stress-reduction techniques also play a role for many people. The most effective treatment plans tend to combine multiple strategies tailored to the severity, pitch, and psychological impact of each person’s tinnitus.
