What does 525 Hz sound like?
525 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 525 Hz sound wave completes 525 cycles every second, so one cycle lasts 1.9 ms. In air at 20 °C, where sound travels at about 343 m/s, each wave is 65.3 cm (2.14 ft) long; in water it stretches to 2.82 m because sound moves about 4.3 times faster there.
Musically, 525 Hz is 6 cents above C5 (523.25 Hz) in standard A440 tuning. Doubling it to 1,050 Hz raises the pitch by one octave; halving it to 262.5 Hz lowers it by one.
