Hearing-range tone
15000 Hz — 15 kHz High Tone
15 kHz is a very high tone near the upper edge of many adults’ hearing, often used in “what’s the highest pitch you can hear” checks.

About the 15000 Hz tone
15 kHz is high enough that whether you hear it depends a lot on both your age and your equipment — many laptop and phone speakers roll off before this point, so silence may just mean the speaker, not your ears.
For the clearest result, try good headphones at a low volume. Treat this as a casual curiosity check rather than a hearing test; anything you are worried about is a question for an audiologist.
Many people can hear 15 kHz but not the 17 kHz “mosquito” tone above it, which makes this a good middle step when you are trying to find the top of your own range. Start here, confirm you can hear it, then move up to 17 kHz and 20 kHz. Because the tone is so high, a pure sine is the honest test — harmonics from other waveforms would sit above 15 kHz, where reproduction is even less reliable.

Frequently asked questions
Can you hear 15000 Hz?
Many adults can, but whether you do depends on both your age and your equipment — plenty of speakers roll off before 15 kHz. It’s a casual curiosity check rather than a hearing test.
I hear nothing at 15 kHz — does that mean my hearing is bad?
Not necessarily. Many laptop speakers and earbuds don’t reproduce 15 kHz at all, so silence often means the gear rather than your ears. Try good headphones at a low volume first; for any real concern, see an audiologist.
What note is 15000 Hz?
15000 Hz is well above the highest note of any orchestral instrument, so it’s pure high treble rather than a hummable pitch. The generator shows the nearest note and cents for reference.
