A tone rises from 8 kHz to 20 kHz over 40 seconds. Press I can no longer hear it when it fades away. It is a check of this device and your ears together, not a hearing test.

Questions people ask
- Is this a hearing test?
- No. Online tests are not calibrated: the answer depends on your headphones and their volume as much as your ears. See an audiologist for a hearing test.
- What is a usual range?
- Young people often hear up to about 17 to 20 kHz, and the top falls with age; the page says only what you heard on this device.
- Is it safe?
- Turn the volume down first and then up slowly; never play high tones loudly.
