What does 1,250 Hz sound like?
1,250 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 1,250 Hz sound wave completes 1,250 cycles every second, so one cycle lasts 800 µs. In air at 20 °C, where sound travels at about 343 m/s, each wave is 27.4 cm (10.80 in) long; in water it stretches to 1.18 m because sound moves about 4.3 times faster there.
Musically, 1,250 Hz is 8 cents above D♯6 (1.245 kHz) in standard A440 tuning. Doubling it to 2,500 Hz raises the pitch by one octave; halving it to 625 Hz lowers it by one.
