What does 850 Hz sound like?

850 Hz is a midrange frequency. It is a clear midrange tone, close to where the human ear does most of its work for speech and melody.

A 850 Hz sound wave completes 850 cycles every second, so one cycle lasts 1.18 ms. In air at 20 °C, where sound travels at about 343 m/s, each wave is 40.4 cm (1.32 ft) long; in water it stretches to 1.74 m because sound moves about 4.3 times faster there.

Musically, 850 Hz is 40 cents above G♯5 (830.61 Hz) in standard A440 tuning. Doubling it to 1,700 Hz raises the pitch by one octave; halving it to 425 Hz lowers it by one.
