A ringing sound in your ear, with no outside source causing it, is called tinnitus. It affects roughly 10 to 25% of adults, and in the vast majority of cases it signals some degree of hearing loss rather than a serious medical condition. About 8 to 9 out of every 10 people with persistent tinnitus have underlying hearing damage, even if they haven’t noticed it yet.
The sound isn’t always a ring. It can present as buzzing, hissing, clicking, whooshing, or humming. It can show up in one ear or both, come and go, or stay constant. Understanding what’s behind it helps you figure out whether it’s something to monitor at home or something worth getting checked.
Why Your Ears Ring
Tinnitus is a symptom, not a disease. Something has changed in the way your auditory system processes sound, and the ringing is the result. The most common trigger is age-related hearing loss. As the tiny hair cells inside your inner ear wear down over time, your brain loses some of the sound input it’s used to receiving. In response, it can generate its own signal, which you perceive as ringing.
Noise exposure is the other major cause. Concerts, power tools, earbuds at high volume, and loud workplaces all damage those same hair cells. The National Institute for Occupational Safety and Health recommends keeping noise exposure below 85 decibels over an eight-hour day to prevent permanent hearing damage. For context, a busy restaurant sits around 80 to 85 decibels. A rock concert can hit 110 or more. Even a single very loud event can trigger ringing that lasts hours, days, or permanently.
Other common causes include earwax buildup pressing against the eardrum, jaw joint problems, head or neck injuries, and sinus congestion. Stress and sleep deprivation don’t cause tinnitus directly, but they reliably make existing ringing feel louder and more intrusive.
Medications That Can Trigger Ringing
Certain drugs are known to cause or worsen tinnitus, usually at higher doses. The effects are almost always reversible once you stop taking them. Common culprits include aspirin (especially at high doses for pain or inflammation), ibuprofen, naproxen, and other over-the-counter anti-inflammatory drugs. The ringing tends to be dose-related: the more you take, the more likely it is to appear.
Some prescription medications carry higher risks. Certain strong antibiotics given intravenously, powerful diuretics used in emergency settings, and specific chemotherapy drugs can all affect hearing. If you notice new ringing after starting a medication, that’s worth mentioning to whoever prescribed it. In most cases, adjusting the dose or switching medications resolves the problem.
When Ringing in One Ear Needs Attention
Tinnitus in both ears is almost always related to general hearing changes and is rarely dangerous. Ringing isolated to one ear deserves a closer look, though the news is usually reassuring. A large review of nearly 1,400 patients with one-sided tinnitus found that only about 0.08% had a benign growth on the hearing nerve (called a vestibular schwannoma). That’s less than 1 in 1,000. Still, persistent one-sided ringing, especially with hearing loss on that same side, is a reasonable reason to get a hearing evaluation.
Pulsatile Tinnitus Is Different
If the sound you hear pulses in rhythm with your heartbeat, that’s a distinct type called pulsatile tinnitus. Unlike the more common ringing or buzzing, pulsatile tinnitus often has a physical, identifiable source. It’s typically caused by changes in blood flow near the ear: narrowed blood vessels, abnormal connections between arteries and veins, or increased pressure in the veins around the brain.
This type warrants prompt medical evaluation. Some of the underlying vascular causes carry a real risk of stroke or vision problems if left unaddressed. The sound itself isn’t dangerous, but it can be a signal that something in your circulatory system needs attention. If you hear a rhythmic whooshing or thumping that matches your pulse, bring it up with your doctor sooner rather than later.
How Tinnitus Is Managed
There’s no pill that turns tinnitus off, but several approaches can reduce how much it affects your daily life. The most effective is addressing any underlying hearing loss. When hearing aids restore the sound input your brain has been missing, tinnitus often fades into the background. Studies show meaningful improvement in about 70% of tinnitus patients fitted with hearing aids.
Tinnitus retraining therapy (TRT) combines counseling with low-level background sound from small wearable devices. The goal is to train your brain to reclassify the ringing as unimportant, the same way you stop noticing the hum of a refrigerator. Multiple clinical centers report success rates around 80% or higher when counseling and sound generators are used together. Initial improvements typically appear around three months in, with the full process taking 12 to 18 months for lasting results. Counseling alone, without the sound component, helps only about 18% of patients.
A newer option called bimodal neuromodulation pairs sound through earbuds with gentle electrical stimulation on the tongue. One FDA-authorized device using this approach showed that about 82% of patients with moderate or worse tinnitus experienced a clinically meaningful reduction in symptoms after 12 weeks of home use. For people with only mild tinnitus, the device showed little benefit, suggesting it works best for those who are more significantly bothered.
Simple Strategies That Help
Many people find relief through everyday adjustments. White noise machines, fans, or nature sound apps can mask the ringing at night when it’s most noticeable. Keeping background sound in your environment, even at low levels, gives your brain something else to process. Reducing alcohol, managing stress, and prioritizing sleep all help keep tinnitus from feeling overwhelming on difficult days.
You may have heard that cutting caffeine helps. There’s actually very little scientific evidence that caffeine worsens tinnitus. The American Tinnitus Association suggests tracking your own experience: if coffee seems to make your ringing louder, reduce it, but if it doesn’t, there’s no reason to give it up. For people who also have Ménière’s disease (an inner ear condition causing vertigo, hearing loss, and tinnitus together), reducing salt intake has a strong correlation with symptom improvement.
Protecting Your Hearing Going Forward
Whether your ringing is new or longstanding, preventing further hearing damage is the single most important thing you can do. Foam earplugs reduce noise by 15 to 30 decibels and cost almost nothing. Wear them at concerts, while mowing the lawn, or when using power tools. If you use earbuds or headphones regularly, keep the volume at 60% or below. Most smartphones now have built-in decibel monitoring that can alert you when levels are too high.
Workplace noise is a major contributor. OSHA requires employers to provide hearing conservation programs when noise levels hit 85 decibels over an eight-hour shift. If your workplace is loud enough that you need to raise your voice to talk to someone three feet away, you’re likely at or above that threshold. Custom-molded earplugs from an audiologist offer better comfort and sound quality than disposable foam for daily use.
