Tinnitus — ringing, hissing or buzzing with no external source — affects 10–25% of adults. It usually accompanies hearing loss: as input from damaged ear hair cells fades, brain auditory circuits raise their gain and their background activity becomes audible. Loud noise, aging, earwax, some 200+ medications, jaw problems and stress all contribute. Most tinnitus fades from awareness with time; when it doesn't, the evidence supports hearing aids (when loss coexists), sound enrichment, and CBT-based habituation therapy — while no medication or supplement has been shown to silence it. One-sided tinnitus, pulsing tinnitus, or tinnitus with sudden hearing loss or dizziness needs prompt assessment.
What tinnitus is
Tinnitus is perception without source — ringing, hissing, buzzing, roaring or humming that only the owner hears. Around 10–25% of adults experience it; for most it is intermittent or ignorable, while for a significant minority it intrudes on sleep, concentration and mood enough to need help.
The modern understanding relocates the problem. Damaged cochlear hair cells send less signal upward; central auditory circuits compensate by raising their gain; and at high enough gain, the system's own spontaneous activity crosses into awareness — a hiss from an amplifier with no instrument plugged in. Attention and emotion then decide how loud it feels: circuits for salience and threat can lock onto the signal (the distress loop) or file it as ignorable (habituation). Every treatment with evidence works on gain, masking or the loop — which is why the honest answer to "what silences it" differs from "what helps".
Causes and contributors
- Hearing loss — the dominant companion: age-related decline and noise damage (concerts, firearms, machinery, earbuds at volume) lead the list; tinnitus is often its first noticed sign
- Earwax blockage — the most satisfying cause, because removal can end it
- Medications — 200+ implicated: high-dose aspirin and NSAIDs, loop diuretics, some antibiotics (aminoglycosides), chemotherapy agents (cisplatin), quinine; usually dose-related, sometimes permanent (a reason never to self-escalate painkillers)
- Ear and jaw mechanics — middle-ear infection or fluid, otosclerosis, TMJ dysfunction (tinnitus that changes with jaw movement), neck injury
- Ménière's disease — tinnitus with episodic vertigo and fluctuating hearing
- Acoustic neuroma — the rare one-sided cause that mandates asymmetry work-ups
- Whole-body contributors — high blood pressure, anemia, thyroid disease, and the stress-sleep loop above
- Pulsatile causes — the vascular list in the FAQ
When tinnitus is a red flag
Same-day assessment: tinnitus arriving with sudden hearing loss — an emergency with a treatment window. Prompt (days-to-weeks) assessment: one-sided tinnitus, pulsatile tinnitus, tinnitus with vertigo, after head injury, or with ear discharge or pain. Routine but real: everything else persistent, via a hearing test — which most tinnitus deserves anyway, since managing the hearing loss is managing the tinnitus.
What actually helps
Treat the treatable: wax removed, middle-ear disease managed, culprit medications reviewed (never stopped unilaterally), blood pressure and thyroid corrected, TMJ addressed.
Hearing aids — for the majority with coexisting loss: restoring input lets the brain lower its gain, and masking rides along free; trials and clinical experience show meaningful tinnitus relief, often the single best move.
Sound enrichment — never silence: environmental sound, bedside generators, apps; some benefit simply from un-silence, formal masking helps others.
CBT-based therapy — the best-evidenced intervention for tinnitus distress: it reliably improves quality of life, sleep and mood even as loudness ratings move less. Tinnitus retraining therapy (counseling plus sound) and newer app-delivered CBT variants extend access.
Sleep and stress work — because the loop runs both ways.
What doesn't: no drug is approved or demonstrated to eliminate tinnitus (medications treat the accompanying insomnia or depression, which is different and sometimes worthwhile); and the supplement aisle built for this symptom — ginkgo trials negative overall, zinc unproven outside deficiency, B12 helpful only if deficient, "silencer" formulas untested — is dissected in Do tinnitus supplements work?. Emerging bimodal-stimulation devices show promise in trials and are worth watching, not buying sight-unseen.
Living with it, practically
Protect remaining hearing (earplugs at volume; the damage that caused it can still compound); keep caffeine and alcohol observations personal rather than doctrinal (evidence is individual); enrich sound at night; and treat the distress as treatable, because it is — the most reliable trajectory in tinnitus is that reaction shrinks even when sound persists. The hearing-loss guide covers the aids question most tinnitus eventually meets.
Frequently asked questions
Will my tinnitus ever go away?
New-onset tinnitus often settles or fades from awareness over weeks to months — especially after a noise exposure or with earwax removal — and even persistent tinnitus typically bothers less over time as the brain habituates. "Permanent and unbearable" is the fear; "persistent but background" is the common trajectory, and habituation therapies exist to speed it.
Why is it so much louder at night?
Silence removes the masking that daytime sound provides, attention has nothing else to hold, and fatigue plus the anxiety loop amplify perception. Bedside sound — fan, quiet radio, purpose-made noise — is the standard, effective counter; sleeping better in turn lowers next-day loudness ratings.
Can anxiety cause tinnitus, or does tinnitus cause anxiety?
Both, in a loop: stress hormones heighten auditory gain and attention locks onto the sound, while the sound itself provokes worry and poor sleep. This loop is precisely why CBT-based approaches — which target the reaction, not the eardrum — outperform every pill tested.
What is pulsatile tinnitus?
Tinnitus that beats with your pulse — usually a blood-flow sound from vessels near the ear. Causes range from benign (high output states, stiffened arteries) to ones needing imaging (vascular malformations, narrowed vessels, raised intracranial pressure). Rhythmic-with-heartbeat tinnitus always earns a medical work-up.
