What does 445 Hz sound like?
445 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 445 Hz sound wave completes 445 cycles every second, so one cycle lasts 2.25 ms. In air at 20 °C, where sound travels at about 343 m/s, each wave is 77.1 cm (2.53 ft) long; in water it stretches to 3.33 m because sound moves about 4.3 times faster there.
Musically, 445 Hz is 20 cents above A4 (440 Hz) in standard A440 tuning. Doubling it to 890 Hz raises the pitch by one octave; halving it to 222.5 Hz lowers it by one.
