What does 550 Hz sound like?
550 Hz is a midrange frequency. It is a clear midrange tone, close to where the human ear does most of its work for speech and melody.
A 550 Hz sound wave completes 550 cycles every second, so one cycle lasts 1.82 ms. In air at 20 °C, where sound travels at about 343 m/s, each wave is 62.4 cm (2.05 ft) long; in water it stretches to 2.69 m because sound moves about 4.3 times faster there.
Musically, 550 Hz is 14 cents below C♯5 (554.37 Hz) in standard A440 tuning. Doubling it to 1,100 Hz raises the pitch by one octave; halving it to 275 Hz lowers it by one.
