What does 770 Hz sound like?
770 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 770 Hz sound wave completes 770 cycles every second, so one cycle lasts 1.3 ms. In air at 20 °C, where sound travels at about 343 m/s, each wave is 44.5 cm (1.46 ft) long; in water it stretches to 1.92 m because sound moves about 4.3 times faster there.
Musically, 770 Hz is 31 cents below G5 (783.99 Hz) in standard A440 tuning. Doubling it to 1,540 Hz raises the pitch by one octave; halving it to 385 Hz lowers it by one.
