What is 2000 Hz?
2000 Hz is a tone in the presence region — detail, edge and consonant sounds. Its nearest musical note is B6 (about +21 cents away), and its sound wave is roughly 0.172 m long in air. Because it is a pure sine wave, it contains only this one frequency with no harmonics, which is exactly what you want for testing and calibration.
2 kHz sits in the 'presence' region where the ear is very sensitive and consonant sounds live. It is a standard audiometric frequency and a good check for clarity and sibilance on a system.
What you can use a 2000 Hz tone for
- Level calibration and equipment checks
- Tinnitus frequency matching (as a starting point)
Can you hear 2000 Hz?
This sits in the range where human hearing is most sensitive, so almost everyone hears it clearly at a low volume. If you are testing your hearing, do it at a modest, consistent volume in a quiet room and compare both ears. For a full walkthrough, see our at-home hearing range test guide. Remember this is a self-check, not a medical diagnosis.
Frequently asked questions
What is a 2000 Hz test tone?
A 2000 Hz test tone is a pure sine wave vibrating 2,000 times per second. It falls in the presence range (detail, edge and consonant sounds) and its nearest musical note is B6. You can play it instantly above to test audio equipment or your hearing.
Can everyone hear 2000 Hz?
This sits in the range where human hearing is most sensitive, so almost everyone hears it clearly at a low volume.
What note is 2000 Hz?
The nearest equal-tempered note to 2000 Hz is B6 (about +21 cents away).
Is it safe to play 2000 Hz?
Yes, at a sensible volume. Start low and raise it gradually. Very loud tones of any frequency can harm hearing or, at very low frequencies, over-drive speakers — so keep levels comfortable and take breaks.
