How high can you hear?

Tone Standby
Level −20 dBFS
Pass Ready

A beep climbs from 8 kHz toward 20 kHz. Tell it when it's gone, and we'll guess the age of your ears.

  • Headphones help. Wired ones if you have them. Plenty of speakers and earbuds fade out above 15 kHz on their own.
  • Never loud. Every beep plays at one fixed, gentle level, and the high ones are never boosted.
  • A party trick, not a hearing test. If you're worried about your hearing, an audiologist can check it properly.
