What does 345 Hz sound like?
345 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 345 Hz sound wave completes 345 cycles every second, so one cycle lasts 2.9 ms. In air at 20 °C, where sound travels at about 343 m/s, each wave is 99.4 cm (3.26 ft) long; in water it stretches to 4.29 m because sound moves about 4.3 times faster there.
Musically, 345 Hz is 21 cents below F4 (349.23 Hz) in standard A440 tuning. Doubling it to 690 Hz raises the pitch by one octave; halving it to 172.5 Hz lowers it by one.
