If you hear a sound in your ears or head that has no outside source, you likely have tinnitus. It’s remarkably common: about 14% of adults experience some form of it, and roughly 2% deal with a severe version. The real question isn’t just whether you have it, but what kind it is, what might be causing it, and whether it needs medical attention.
What Tinnitus Actually Sounds Like
Tinnitus doesn’t sound the same for everyone. The classic description is “ringing in the ears,” but that only captures one version. People describe their tinnitus as sounding like crickets, wind, running water, escaping steam, a humming engine, or a high-pitched tone like a fluorescent light. Some hear buzzing, hissing, or clicking. It can be constant or come and go, and it might show up in one ear, both ears, or seem to come from somewhere inside your head.
In the vast majority of cases, the sound is only audible to you. This is called subjective tinnitus, and it accounts for nearly all cases. In rare instances, a doctor can actually hear the sound coming from your ear canal using a stethoscope. That version, sometimes called objective tinnitus, usually has a mechanical cause like a blood vessel issue or muscle spasm near the ear.
Temporary Ringing vs. Chronic Tinnitus
Almost everyone has experienced a brief ring in the ears after a loud concert, a flight, or even a quiet room. That kind of fleeting noise, lasting seconds to minutes, is normal and not considered clinical tinnitus. The distinction comes down to how long it lasts and how often it returns.
Researchers generally classify tinnitus that has been present for less than three months as acute. If it persists beyond six months, it’s considered chronic. There’s a gray area between three and six months sometimes labeled sub-acute. If you’ve been noticing a persistent sound for weeks and it isn’t fading, that’s worth paying attention to. Not because it’s necessarily dangerous, but because early evaluation gives you more options if treatment is needed.
Signs That Point to a Specific Cause
Tinnitus itself is a symptom, not a disease. What matters is the pattern of symptoms around it, because those patterns can point toward different causes.
If your tinnitus comes with episodes of intense spinning dizziness (lasting 20 minutes to several hours), hearing loss, and a feeling of pressure or fullness in one ear, that combination suggests Ménière’s disease, an inner ear disorder. The dizziness episodes may come on suddenly or follow a short period of increased tinnitus or muffled hearing.
If the sound changes when you clench your jaw, turn your head, or press on your neck, you may have what’s called somatic tinnitus. In these cases, the sound is being influenced by nerve signals from your jaw joint or upper neck rather than by damage to the hearing system itself. A large percentage of people with tinnitus can modulate their sound this way, and it suggests that muscle tension, jaw problems, or neck issues could be contributing.
If you recently started a new medication or increased a dosage, that’s worth investigating. Several common drug classes can trigger or worsen tinnitus. High-dose aspirin is a well-known culprit. Certain antibiotics (particularly macrolides like azithromycin when used long-term at high doses), loop diuretics used for heart failure or kidney disease, and some chemotherapy drugs can all affect hearing. Combining two of these medications raises the risk significantly.
Pulsatile Tinnitus Is Different
One form of tinnitus stands apart from the rest. If the sound you hear is a rhythmic whooshing or thumping that matches your heartbeat, that’s pulsatile tinnitus. You can check this by feeling your pulse at your wrist while listening to the sound. If they sync up, you’re essentially hearing blood flowing through vessels near your ears.
Pulsatile tinnitus has a physical, identifiable cause more often than other types. It can result from conditions that change blood flow near the ear: high blood pressure, anemia, atherosclerosis (buildup in artery walls), or an overactive thyroid that speeds up the heart. In some cases, it’s caused by abnormal blood vessel formations near the ear or increased pressure from cerebrospinal fluid around the brain. Because it can be the first sign of a treatable vascular condition, pulsatile tinnitus warrants a medical evaluation, especially if it’s new.
How Severity Is Measured
Tinnitus ranges from a minor background noise you barely notice to a sound that disrupts sleep, concentration, and emotional well-being. If you’re trying to gauge where you fall, audiologists use a standardized questionnaire called the Tinnitus Handicap Inventory. It’s a 25-question survey that scores from 0 to 100:
- 0 to 16: Slight or no impact on daily life
- 18 to 36: Mild impact, noticeable but manageable
- 38 to 56: Moderate impact, interfering with some daily activities
- 58 to 76: Severe impact, significantly affecting quality of life
- 78 to 100: Catastrophic impact, disabling
You can find this questionnaire online through university audiology programs. It won’t diagnose what’s causing your tinnitus, but it gives you a clear way to describe its severity to a healthcare provider and track whether it’s improving or worsening over time.
What a Clinical Evaluation Involves
If you decide to get checked, the process typically starts with a hearing test. Many people with tinnitus have some degree of hearing loss they haven’t noticed, and the pattern of that loss helps identify the cause. A tinnitus-specific evaluation goes further, using specialized tests to measure the pitch of the sound you’re hearing, its loudness, and the minimum level of external noise needed to cover it up. These measurements help guide treatment decisions.
For pulsatile tinnitus or tinnitus that’s only in one ear, imaging studies may be ordered to look at blood vessels and structures near the ear.
Symptoms That Need Urgent Attention
Most tinnitus is not an emergency. But certain combinations of symptoms call for immediate or same-day evaluation.
Go to an emergency room if your tinnitus appears alongside facial weakness or numbness, new weakness on one side of your body, difficulty speaking, severe and sudden headache, loss of consciousness, or symptoms following a head injury (especially if there’s blood or fluid from the ear).
Get evaluated the same day if you experience sudden hearing loss in one or both ears developing over hours to three days, a sudden muffled feeling in one ear with new tinnitus, or severe dizziness with a new change in hearing. Sudden hearing loss in particular is treated as a time-sensitive condition because early treatment improves outcomes.
New pulsatile tinnitus or tinnitus that’s clearly worse in one ear should be evaluated within days, even without other symptoms. One-sided tinnitus occasionally signals a growth on the hearing nerve, which is typically benign but benefits from early detection.
