A sudden hearing loss in one or both ears should be medically assessed promptly — in the case of marked loss, within 24 hours. If there is no obvious cause in the outer ear or middle ear, a sudden sensorineural hearing loss may be present. Often a so-called sudden hearing loss (Hörsturz) is suspected, the exact cause of which frequently remains unclear. Some affected persons additionally notice a feeling of pressure or a ringing/noise in the ear (tinnitus). The earlier an assessment is carried out, the better the condition can be classified.
Possible causes
Sudden sensorineural hearing loss
A sudden loss of hearing without any identifiable external cause. In many cases, the cause remains unexplained; possible factors under discussion include impaired blood flow, inflammation, and viral infections of the inner ear.
Blockage due to earwax
A plug in the ear canal can rapidly impair hearing and is easily identified during examination.
Infection of the inner or middle ear
An inflammation can temporarily affect sound conduction or the inner ear.
Pressure damage
Noise, acoustic trauma, or severe pressure fluctuations can reduce hearing temporarily or for longer periods.

Typical steps at the doctor's office
- 1In the ENT practice, the eardrum is examined and a hearing test is performed to determine the type and extent of hearing impairment.
- 2Additionally, balance tests or further inner ear tests, and in some cases imaging examinations, may be appropriate.
- 3Further treatment depends on the results and will be discussed individually with your doctor.
What you can do yourself
- Stay calm and temporarily avoid loud environments and noise.
- Do not probe inside the ear and do not attempt any rinsing or cleaning procedures yourself.
- Reduce stressful stress as much as possible.
- Note any observations such as dizziness or ringing in the ears to describe them at your appointment.
A sudden significant hearing loss should be assessed the same day, at the latest within 24 hours, at an ENT practice or through an emergency service — even if hearing has partially recovered. If facial paralysis, speech disturbance, or paralysis occur as well: call 144 immediately.

Frequently asked questions
- Does sudden sensorineural hearing loss resolve on its own?
- This is possible, but not predictable. An early examination helps to assess the situation correctly.
- Can stress affect hearing?
- Stress and tension are frequently mentioned as accompanying factors. The connection is individual and will be evaluated during the consultation.
