What does 475 Hz sound like?
475 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 475 Hz sound wave completes 475 cycles every second, so one cycle lasts 2.11 ms. In air at 20 °C, where sound travels at about 343 m/s, each wave is 72.2 cm (2.37 ft) long; in water it stretches to 3.12 m because sound moves about 4.3 times faster there.
Musically, 475 Hz is 33 cents above A♯4 (466.16 Hz) in standard A440 tuning. Doubling it to 950 Hz raises the pitch by one octave; halving it to 237.5 Hz lowers it by one.
