What does 340 Hz sound like?
340 Hz is a low midrange frequency. It sits in the low midrange: a rounded, full tone in the region of male and female speaking voices and the lower notes of a piano.
A 340 Hz sound wave completes 340 cycles every second, so one cycle lasts 2.94 ms. In air at 20 °C, where sound travels at about 343 m/s, each wave is 1.01 m (3.31 ft) long; in water it stretches to 4.36 m because sound moves about 4.3 times faster there.
Musically, 340 Hz is 46 cents below F4 (349.23 Hz) in standard A440 tuning. Doubling it to 680 Hz raises the pitch by one octave; halving it to 170 Hz lowers it by one.
