What does 396 Hz sound like?
396 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 396 Hz sound wave completes 396 cycles every second, so one cycle lasts 2.53 ms. In air at 20 °C, where sound travels at about 343 m/s, each wave is 86.6 cm (2.84 ft) long; in water it stretches to 3.74 m because sound moves about 4.3 times faster there.
Musically, 396 Hz is 18 cents above G4 (392 Hz) in standard A440 tuning. Doubling it to 792 Hz raises the pitch by one octave; halving it to 198 Hz lowers it by one.
