What does 650 Hz sound like?
650 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 650 Hz sound wave completes 650 cycles every second, so one cycle lasts 1.54 ms. In air at 20 °C, where sound travels at about 343 m/s, each wave is 52.8 cm (1.73 ft) long; in water it stretches to 2.28 m because sound moves about 4.3 times faster there.
Musically, 650 Hz is 24 cents below E5 (659.26 Hz) in standard A440 tuning. Doubling it to 1,300 Hz raises the pitch by one octave; halving it to 325 Hz lowers it by one.
