What does 1,633 Hz sound like?
1,633 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 1,633 Hz sound wave completes 1,633 cycles every second, so one cycle lasts 612 µs. In air at 20 °C, where sound travels at about 343 m/s, each wave is 21.0 cm (8.27 in) long; in water it stretches to 90.7 cm because sound moves about 4.3 times faster there.
Musically, 1,633 Hz is 30 cents below G♯6 (1.661 kHz) in standard A440 tuning. Doubling it to 3,266 Hz raises the pitch by one octave; halving it to 816.5 Hz lowers it by one.
