8 kHz Tone Generator
A free online tone generator producing a pure 8 kHz signal in your browser. High-frequency hearing test. Pick a waveform, hit play, and adjust the volume slowly.
What is 8 kHz used for?
8 kHz is in the upper hearing range. Most adults under 30 hear it clearly; many over 50 don't — a quick way to gauge high-frequency hearing loss.
For high-frequency hearing test, set the volume to roughly 30% before pressing play. 8 kHz can sound deceptively quiet at full volume — always start low to protect your speakers and ears.
How to use it
Press the play button on the preview above to hear 8 kHz immediately. To customize the waveform (sine, square, sawtooth, triangle), tweak the volume curve, or add a second tone for beat-frequency comparison, open the full tone generator. The closest musical pitch to 8 kHz is approximately B8 (+21¢).
FAQs
Why does 8 kHz sound different on different speakers?
Speaker frequency response varies dramatically. Small monitors and laptop speakers struggle below about 80 Hz; tweeters distort above 16 kHz on cheaper systems. If 8 kHz sounds quiet, distorted, or buzzy, your hardware is likely the limit — not the tone itself.
Is it safe to listen to 8 kHz?
At reasonable volumes, yes. Sustained exposure to any frequency at high volume can damage your hearing. Always start at 0 volume, ramp up slowly, and don't wear headphones at full volume on this page.
What's the closest musical note to 8 kHz?
8 kHz corresponds to approximately B8 (+21¢). For exact tuning, use the chromatic tuner.
