What does 495 Hz sound like?
495 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 495 Hz sound wave completes 495 cycles every second, so one cycle lasts 2.02 ms. In air at 20 °C, where sound travels at about 343 m/s, each wave is 69.3 cm (2.27 ft) long; in water it stretches to 2.99 m because sound moves about 4.3 times faster there.
Musically, 495 Hz is almost exactly B4 (493.88 Hz) in standard A440 tuning. Doubling it to 990 Hz raises the pitch by one octave; halving it to 247.5 Hz lowers it by one.
