Imaging / functional test
Audiometry
Other names and abbreviations: hearing test, pure-tone audiometry
A hearing test – it shows how well you hear sounds of different pitches.
You sit in a soundproof booth and signal when you hear a sound. The result is an audiogram – a hearing chart for both ears.
Typical ranges in adults
| Parameter | Typical range | What a deviation may mean |
|---|---|---|
| Hearing threshold | up to 20–25 dB | higher: hearing loss |
The ranges are approximate and differ between laboratories; they also depend on age, sex and pregnancy. A result outside the range doesn't always mean illness – discuss it with a doctor.
When it is done
With hearing loss, tinnitus, in occupational medicine.
How to prepare
Avoid loud places (concerts, noise) the day before.
