What does 355 Hz sound like?
355 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 355 Hz sound wave completes 355 cycles every second, so one cycle lasts 2.82 ms. In air at 20 °C, where sound travels at about 343 m/s, each wave is 96.6 cm (3.17 ft) long; in water it stretches to 4.17 m because sound moves about 4.3 times faster there.
Musically, 355 Hz is 28 cents above F4 (349.23 Hz) in standard A440 tuning. Doubling it to 710 Hz raises the pitch by one octave; halving it to 177.5 Hz lowers it by one.
