What does 670 Hz sound like?
670 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 670 Hz sound wave completes 670 cycles every second, so one cycle lasts 1.49 ms. In air at 20 °C, where sound travels at about 343 m/s, each wave is 51.2 cm (1.68 ft) long; in water it stretches to 2.21 m because sound moves about 4.3 times faster there.
Musically, 670 Hz is 28 cents above E5 (659.26 Hz) in standard A440 tuning. Doubling it to 1,340 Hz raises the pitch by one octave; halving it to 335 Hz lowers it by one.
