What does 875 Hz sound like?
875 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 875 Hz sound wave completes 875 cycles every second, so one cycle lasts 1.14 ms. In air at 20 °C, where sound travels at about 343 m/s, each wave is 39.2 cm (1.29 ft) long; in water it stretches to 1.69 m because sound moves about 4.3 times faster there.
Musically, 875 Hz is 10 cents below A5 (880 Hz) in standard A440 tuning. Doubling it to 1,750 Hz raises the pitch by one octave; halving it to 437.5 Hz lowers it by one.
