Tinnitus, the perception of ringing, buzzing, or whooshing in your ears without an external sound source, affects roughly 14.4% of adults worldwide. About 10% experience it chronically, meaning it lasts longer than three months. The triggers range from a single loud concert to ongoing medication use, jaw problems, or stress, and understanding which ones apply to you is the first step toward managing it.
How Tinnitus Starts in the Brain
Tinnitus isn’t actually a problem with your ears alone. It begins when the tiny structures inside your inner ear that detect sound get damaged. Your inner ear has two types of sensory cells: one type amplifies incoming sound (boosting quiet signals by up to 50 decibels), and another type converts sound into electrical signals that travel to the brain. Noise, aging, and certain drugs tend to damage the amplifier cells first, because they’re more fragile.
When those amplifier cells stop working but the signal-converting cells remain intact, the brain receives a distorted mix of input. Neurons in the early stages of the hearing pathway become overactive because they’re no longer getting the inhibitory signals the amplifier cells used to provide. The brain interprets that spontaneous neural firing as sound. In many ways, tinnitus is to hearing what phantom limb pain is to touch: the brain fills in a signal that isn’t there anymore, driven by changes in how auditory circuits reorganize after damage.
Noise Exposure
Loud sound is the single most common trigger. The National Institute for Occupational Safety and Health sets the safe exposure limit at 85 decibels averaged over an eight-hour workday, roughly the volume of heavy city traffic. For every 3-decibel increase above that, the safe exposure time cuts in half. A rock concert at 100 decibels can start causing damage in under 15 minutes.
You may notice temporary ringing after a loud event, a sign that the amplifier cells in your inner ear have been stressed. For most people, this fades within hours or a day. But repeated episodes cause cumulative, irreversible damage. Construction workers, musicians, military personnel, and anyone who regularly uses earbuds at high volume are at elevated risk. The ringing that initially comes and goes can eventually become permanent once enough of those sensory cells are destroyed.
Medications That Affect Hearing
Certain drugs are known to be “ototoxic,” meaning they can damage the inner ear. The most well-established culprits include high-dose aspirin and related compounds, certain antibiotics (particularly macrolide types like azithromycin and clarithromycin when used at high doses over long periods), and platinum-based chemotherapy drugs like cisplatin. In some cases, the tinnitus resolves once the medication is stopped. In others, particularly with chemotherapy agents, the damage can be permanent.
If you notice new ringing after starting a medication, it’s worth raising with whoever prescribed it. The risk often depends on dosage and duration rather than simply being on the drug at all.
Jaw and Neck Problems
Not all tinnitus originates in the ear. Disorders of the temporomandibular joint (the hinge connecting your jaw to your skull) are a well-documented trigger, particularly in younger women. People with jaw problems often describe tinnitus that changes in pitch or volume when they move their head, clench their jaw, or press on their face or neck. This is called somatic tinnitus.
The connection exists because nerve fibers from the jaw and neck feed into the same brainstem region that processes early auditory signals. When those somatic nerves are irritated by joint dysfunction, muscle tension, or neck pain, they can amplify or distort activity in the hearing pathway. Stress tends to make this worse, because it increases jaw clenching and muscle tension. If your tinnitus changes when you move your jaw or turn your head, a musculoskeletal cause is worth investigating.
Blood Flow and Pulsatile Tinnitus
A distinct type called pulsatile tinnitus sounds like a rhythmic whooshing or thumping that keeps time with your heartbeat. Unlike the more common steady ringing, this form has a physical source: you’re hearing turbulent blood flow through vessels near your ears. High blood pressure, narrowed arteries, and changes in blood vessel structure near the ear can all cause it.
Pulsatile tinnitus is less common than the standard variety, but it’s important because it often points to an identifiable vascular issue that can sometimes be treated directly. If you hear a rhythmic pulse in your ear, especially on one side, that’s a different clinical picture from the constant tone most people describe.
Inner Ear Conditions
Ménière’s disease is a classic example of an inner ear disorder that produces tinnitus as part of a larger symptom cluster. The diagnostic picture includes episodes of vertigo lasting 20 minutes to 12 hours (sometimes up to 24), confirmed hearing loss (often in low frequencies), and tinnitus or a feeling of fullness in the affected ear. Between attacks, balance typically returns to normal, but the tinnitus and hearing loss can become more persistent over time.
Other inner ear triggers include sudden hearing loss, ear infections, benign growths on the auditory nerve, and age-related hearing decline. Any condition that disrupts the delicate mechanics of the inner ear or the nerve pathways leaving it can potentially set off tinnitus.
Stress, Anxiety, and the Feedback Loop
Stress doesn’t just make you notice tinnitus more. It can actively make it louder. The body’s main stress response system, the hormonal chain running from the brain to the adrenal glands, is frequently disrupted in people with tinnitus. Chronic stress elevates cortisol, which directly affects the inner ear by altering how its cells function at a molecular level. Cortisol also acts on brain regions involved in emotion and memory, particularly the amygdala, which helps explain why tinnitus and anxiety so often reinforce each other.
This creates a genuine feedback loop: tinnitus causes distress, distress raises cortisol, elevated cortisol amplifies the neural signals perceived as tinnitus, and the louder tinnitus causes more distress. The same hormonal disruptions are common in anxiety and depression, which is why all three conditions frequently overlap. Breaking the cycle with stress management, cognitive behavioral approaches, or treatment for underlying anxiety can measurably reduce how severe the tinnitus feels, even if the underlying hearing damage hasn’t changed.
Diet: Caffeine, Salt, and Alcohol
You’ll find plenty of advice online telling you to cut caffeine, alcohol, and salt to reduce tinnitus. The evidence is more nuanced than that. A large-scale survey found that caffeine negatively affected tinnitus severity in about 16% of respondents, salt in about 10%, and alcohol in about 13%. For the vast majority of people, these dietary factors had no noticeable effect at all, and the changes reported were mostly mild.
That said, broader dietary patterns may matter more than any single ingredient. A longitudinal study of over 3,000 women found that those eating diets high in fiber and protein and low in sodium and saturated fat had a 25 to 30% lower risk of hearing threshold changes over three years compared to those with less healthful diets. Rather than obsessing over your morning coffee, the better strategy is likely an overall anti-inflammatory eating pattern that supports cardiovascular and nerve health.
Multiple Triggers Often Overlap
For most people, tinnitus isn’t caused by a single factor. A person might have mild age-related hearing loss that they barely notice, combined with a stressful job and a jaw-clenching habit. Any one of those alone might not produce noticeable tinnitus, but together they push the system past a threshold. This is why tinnitus often seems to appear “out of nowhere” during a stressful period, or why it gets worse with poor sleep, illness, or increased noise exposure, even in someone who’s had quiet ears for years.
Identifying your personal triggers often involves working backward: tracking when the tinnitus spikes and what changed in the hours or days before. For some people, it’s clearly noise. For others, it’s a medication, a jaw problem, or a period of intense stress. Often, it’s a combination, and addressing even one contributing factor can bring meaningful relief.
