What does 790 Hz sound like?
790 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 790 Hz sound wave completes 790 cycles every second, so one cycle lasts 1.27 ms. In air at 20 °C, where sound travels at about 343 m/s, each wave is 43.4 cm (1.42 ft) long; in water it stretches to 1.87 m because sound moves about 4.3 times faster there.
Musically, 790 Hz is 13 cents above G5 (783.99 Hz) in standard A440 tuning. Doubling it to 1,580 Hz raises the pitch by one octave; halving it to 395 Hz lowers it by one.
