Tinnitus: Causes, Diagnosis
& What Really Helps with Ear Sounds
At a glance
FrequencyTinnitus is among the most common ENT complaints; in a relevant proportion of people, it becomes chronic
DefinitionChronic tinnitus = ear sounds that have lasted at least three months and cause distress
Not dangerousTinnitus is generally not a sign of serious disease — but can considerably affect quality of life
TreatmentCounselling, CBT, hearing aids, self-help — no medications with proven efficacy against chronic tinnitus

ICD-10H93.1 (Tinnitus)
1. What is tinnitus?
Tinnitus is the perception of sounds in the ear or head without any external sound source — beeping, whistling, hissing, humming or ringing. Almost everyone experiences brief tinnitus occasionally — that is normal and generally harmless.¹
It becomes a problem when tinnitus does not subside. It is considered chronic when it has lasted at least three months and causes distress. Distress is highly individual — some people can ignore their tinnitus well, others suffer considerably from sleep disorders, concentration problems, anxiety or depression.¹,²
Tinnitus is generally not a sign of danger
The vast majority of cases are benign. Nevertheless, an assessment should take place to rule out treatable causes.
2. Causes
Tinnitus is a symptom, not a disease in itself. The causes are diverse.¹
Hearing loss
The most common cause. Tinnitus almost always occurs together with some hearing impairment — even if not yet noticed. The tinnitus frequency typically lies in the area of greatest hearing loss.
Noise damage
Noise exposure (e.g. concerts, occupational noise, headphones at high volume) can trigger both acute and chronic tinnitus.
Sudden hearing loss
Sudden unilateral hearing loss, often associated with tinnitus.
Ear conditions
Middle ear infection, earwax impaction, otosclerosis.
Stress and psychological strain
Stress does not directly cause tinnitus, but it can considerably amplify perception and distress. Depression and anxiety disorders frequently occur with distressing tinnitus.
Jaw joint and cervical spine
Temporomandibular joint dysfunction (TMD/CMD) or tension in the cervical spine can trigger or worsen tinnitus.
Medications (ototoxic)
Some medications can cause tinnitus as a side effect — including certain antibiotics, high-dose NSAIDs, loop diuretics, chemotherapy agents.
Rare but important: pulsatile tinnitus
Acoustic neuroma (a benign tumour of the auditory nerve) and vascular anomalies (pulsatile tinnitus) are rare but important differential diagnoses. Pulsatile tinnitus (synchronised with the heartbeat) should always be assessed.
3. Symptoms and distress
Forms of tinnitus
- Unilateral or bilateral
- Various sound characters: beeping, whistling, hissing, humming, ringing, chirping
- Tonal tinnitus (single tone) or hissing tinnitus
- Pulsatile tinnitus (synchronised with the heartbeat) — should always be assessed
Accompanying symptoms
- Sleep disorders — the most common accompanying complaint
- Concentration problems
- Anxiety, tension, irritability
- Depressive mood up to depression
- Social withdrawal
Distress > loudness
Guidelines emphasise: tinnitus distress depends less on the loudness of the sound and more on psychological processing and accompanying comorbidities.¹
4. Diagnosis
- ENT examination: otoscopy (ear examination), hearing test (audiogram). Hearing loss is typically found in chronic tinnitus.
- Tinnitus questionnaire: standardised tools (e.g. Tinnitus Handicap Inventory, THI) capture the severity of distress and inform treatment planning.
- Tinnitus matching: determination of tinnitus frequency and loudness — can be useful for treatment.
- Workup of comorbidities: depression, anxiety disorders, sleep disorders, jaw joint problems, cervical spine issues.
- Imaging: typically only with unilateral tinnitus (to rule out acoustic neuroma) or pulsatile tinnitus (vascular workup). Not routinely needed.
