What does 775 Hz sound like?
775 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 775 Hz sound wave completes 775 cycles every second, so one cycle lasts 1.29 ms. In air at 20 °C, where sound travels at about 343 m/s, each wave is 44.3 cm (1.45 ft) long; in water it stretches to 1.91 m because sound moves about 4.3 times faster there.
Musically, 775 Hz is 20 cents below G5 (783.99 Hz) in standard A440 tuning. Doubling it to 1,550 Hz raises the pitch by one octave; halving it to 387.5 Hz lowers it by one.
