Tinnitus Causes: 10 Common Reasons for Ringing in the Ears

What Is Tinnitus?

Tinnitus is a sound perception without an external sound source. NIDCD describes common sounds as ringing, buzzing, roaring, whistling, humming, clicking, hissing, or squealing.

Most tinnitus is subjective, meaning only the person experiencing it can hear it. Less commonly, tinnitus may be rhythmic or pulse-synchronous. Some tinnitus changes when the head, neck, eyes, jaw, or other body areas move; this is sometimes called somatosensory tinnitus.

NIDCD estimates that about 10% to 25% of adults experience tinnitus. It may improve, stay stable, or become chronic.

1. Hearing Loss

Hearing loss is one of the strongest associations with tinnitus. NIDCD notes that most people with tinnitus have some degree of hearing loss, although not everyone with hearing loss develops tinnitus.

Hearing loss may be related to:

• aging
• long-term loud-noise exposure
• ear disease
• genetic factors
• selected medicines or medical treatments

Tinnitus does not prove that hearing loss is present. A professional hearing test is the appropriate way to check.

2. Loud-Noise Exposure

Loud sound can damage sensitive structures in the inner ear and can cause both noise-induced hearing loss and tinnitus.

Risk can come from a single intense sound or repeated exposure over time, including:

• gunfire or explosions
• concerts and amplified music
• power tools
• industrial machinery
• motor sports
• fireworks
• headphones or earbuds used at damaging sound levels

NIDCD notes that long or repeated exposure at or above about 85 dBA can cause hearing loss, while very loud sounds can cause damage much faster. Risk depends on sound level, duration, and distance.

3. Medicines and Medical Treatments

Tinnitus can occur as a side effect of selected medicines, particularly at higher doses in some cases.

NIDCD lists associations with:

• NSAIDs such as ibuprofen and naproxen
• aspirin, especially at higher doses
• certain antibiotics
• selected anti-cancer medicines
• some antimalarial medicines
• some antidepressants

This does not mean that everyone taking one of these medicines will develop tinnitus, or that a medicine is automatically the cause when tinnitus appears.

If tinnitus begins after starting a medicine or changing the dose, bring the full medicine and supplement list to the prescriber or pharmacist. Do not stop prescribed treatment independently.

4. Earwax, Ear Infection, or Middle-Ear Problems

Earwax blocking the ear canal and fluid related to an ear infection can trigger tinnitus. These causes may be more reversible than tinnitus associated with permanent hearing damage.

Potential clues include:

• muffled hearing
• ear fullness
• ear pain
• discharge
• recent respiratory or ear infection

Do not insert cotton swabs, ear candles, essential oils, hairpins, or other objects into the ear canal. An examination can determine whether wax, infection, fluid, or another ear problem is present.

5. Head or Neck Injury

Head or neck injury can affect structures of the ear, the auditory nerve, or brain regions involved in sound processing and may lead to tinnitus.

Tinnitus after significant head trauma should not be treated as a routine home-care problem. NHS guidance treats tinnitus following a head injury as requiring emergency assessment, particularly when other neurological or ear symptoms are present.

6. Jaw-Joint Problems and Teeth Grinding

Temporomandibular-joint problems, jaw clenching, and tooth grinding can cause or worsen tinnitus in some people.

A jaw contribution is more plausible when tinnitus changes with:

• opening or closing the jaw
• clenching
• chewing
• tooth grinding
• pressure around the jaw muscles

That pattern does not prove TMJ dysfunction. Dental or musculoskeletal assessment is more appropriate than assuming every tinnitus case comes from jaw tension.

7. Ménière’s Disease

Ménière’s disease is a less common inner-ear condition that can cause tinnitus together with:

• episodes of vertigo
• hearing loss
• ear pressure or fullness
• nausea or vomiting during attacks

These symptoms do not automatically mean Ménière’s disease. NHS guidance notes that ear infections, labyrinthitis, vestibular neuritis, and migraine can produce overlapping symptoms.

Diagnosis requires professional assessment.

8. Blood-Vessel Conditions and Pulsatile Tinnitus

Pulsatile tinnitus is tinnitus that follows or appears synchronized with the heartbeat. It deserves separate evaluation because some cases have a physical or vascular cause.

NIDCD links tinnitus to blood-vessel problems including high blood pressure, atherosclerosis, and vascular malformations. However, a pulse-synchronous sound should not simply be labeled “high blood pressure tinnitus” without evaluation.

NICE recommends imaging for pulsatile tinnitus. The exact imaging depends on the examination findings and suspected source.

9. Chronic Medical Conditions

NIDCD notes associations between tinnitus and several chronic conditions, including:

• diabetes
• migraine
• thyroid disorders
• anemia
• selected autoimmune disorders

An association does not prove that one of these conditions caused a particular person's tinnitus. Testing should be guided by symptoms, examination, medical history, and clinician judgment rather than by an automatic large laboratory panel.

10. Rare Structural or Tumor-Related Causes

Most tinnitus is not caused by a tumour. However, rare structural or tumour-related disorders can cause tinnitus.

NIDCD lists vestibular schwannoma, also called acoustic neuroma, among possible tumour-related causes. Persistent one-sided tinnitus or asymmetric hearing loss is one reason clinicians may consider specialist evaluation and, in selected cases, MRI.

This does not mean that unilateral tinnitus equals a tumour. NICE specifically describes referral and imaging as evaluation steps, not as proof of a serious diagnosis.

Where Does Stress Fit Into Tinnitus?

Stress can make tinnitus more noticeable or more distressing, but it should not be presented as the universal underlying cause.

Stress may affect:

• attention to the tinnitus sound
• sleep
• anxiety
• jaw clenching and muscle tension
• ability to cope with symptoms

Relaxation, counselling, sleep care, and CBT may help reduce the impact of tinnitus even when they do not change the underlying hearing-related cause.

How Is the Cause of Tinnitus Evaluated?

Evaluation usually begins with the history and an ear examination.

A clinician may ask:

• when tinnitus started
• whether it began suddenly or gradually
• whether it affects one or both ears
• whether it follows the heartbeat
• whether hearing changed
• whether dizziness, ear pain, pressure, or discharge is present
• whether there was recent loud-noise exposure
• whether there was a head or neck injury
• whether jaw movement changes the sound
• which medicines and supplements are being used
• how tinnitus affects sleep, concentration, mood, and daily life

NIDCD notes that primary-care assessment may identify earwax or infection, while ENT and audiology evaluation can investigate hearing and other possible causes.

Why a Hearing Test Matters

NICE recommends offering an audiological assessment to people with tinnitus.

A hearing assessment can identify:

• hearing loss that was not previously recognized
• differences between the ears
• speech-understanding difficulty
• selected middle-ear problems
• whether hearing-aid assessment may be appropriate

For broader testing guidance, visit the Medical Tests & Screenings Hub.

Does Everyone With Tinnitus Need a Scan?

No.

NICE advises against imaging for symmetrical non-pulsatile tinnitus when there are no associated neurological, hearing, ear, or head-and-neck signs.

Imaging may be appropriate for:

• pulsatile tinnitus
• unilateral or asymmetric non-pulsatile tinnitus
• neurological signs
• asymmetric hearing loss
• a suspected structural ear or blood-vessel disorder

The correct scan depends on the suspected cause.

Which Tinnitus Causes May Be Preventable?

Not all tinnitus can be prevented, but noise-related hearing damage is preventable.

NIDCD recommends:

• turning down sound when possible
• moving away from loud noise
• reducing exposure duration
• using properly fitted earplugs or earmuffs around hazardous noise
• having hearing tested if you think hearing has changed

There is no universal “60/60 rule” that guarantees safe headphone listening. Actual risk depends on the sound level, duration, device, environment, and individual exposure.

What About Home Care While the Cause Is Being Evaluated?

Home care can support coping but should not delay appropriate assessment.

Low-risk options may include:

• gentle background sound at a comfortable level
• a consistent sleep routine
• relaxation strategies
• safe hearing protection around truly hazardous noise
• avoiding continuous earplug use in ordinary safe environments
• keeping a brief symptom and trigger diary

There is no universal tinnitus diet. Do not automatically eliminate caffeine, salt, alcohol, sugar, or multiple food groups unless a repeated personal pattern or another medical condition provides a reason.
