3,800 Hz tone

Play a 3,800 Hz tone online, see what note it is, how long its wave is and which animals can hear it. It is a bright, penetrating tone in the region where human hearing is most sensitive – the reason alarms, whistles and baby cries live here.

Start with your device volume low. Very low tones may be inaudible on phone or laptop speakers; very high tones can be uncomfortable on headphones.

What does 3,800 Hz sound like?

3,800 Hz is a upper midrange frequency. It is a bright, penetrating tone in the region where human hearing is most sensitive – the reason alarms, whistles and baby cries live here.

A 3,800 Hz sound wave completes 3,800 cycles every second, so one cycle lasts 263 µs. In air at 20 °C, where sound travels at about 343 m/s, each wave is 9.0 cm (3.55 in) long; in water it stretches to 39.0 cm because sound moves about 4.3 times faster there.

Musically, 3,800 Hz is 33 cents above A♯7 (3.729 kHz) in standard A440 tuning. Doubling it to 7,600 Hz raises the pitch by one octave; halving it to 1,900 Hz lowers it by one.
