What does 750 Hz sound like?
750 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 750 Hz sound wave completes 750 cycles every second, so one cycle lasts 1.33 ms. In air at 20 °C, where sound travels at about 343 m/s, each wave is 45.7 cm (1.50 ft) long; in water it stretches to 1.97 m because sound moves about 4.3 times faster there.
Musically, 750 Hz is 23 cents above F♯5 (739.99 Hz) in standard A440 tuning. Doubling it to 1,500 Hz raises the pitch by one octave; halving it to 375 Hz lowers it by one.
