What does 1,800 Hz sound like?
1,800 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 1,800 Hz sound wave completes 1,800 cycles every second, so one cycle lasts 556 µs. In air at 20 °C, where sound travels at about 343 m/s, each wave is 19.1 cm (7.50 in) long; in water it stretches to 82.3 cm because sound moves about 4.3 times faster there.
Musically, 1,800 Hz is 39 cents above A6 (1.76 kHz) in standard A440 tuning. Doubling it to 3,600 Hz raises the pitch by one octave; halving it to 900 Hz lowers it by one.
