Start with your device volume low. Very low tones may be inaudible on phone or laptop speakers; very high tones can be uncomfortable on headphones.
What does 585 Hz sound like?
585 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 585 Hz sound wave completes 585 cycles every second, so one cycle lasts 1.71 ms. In air at 20 °C, where sound travels at about 343 m/s, each wave is 58.6 cm (1.92 ft) long; in water it stretches to 2.53 m because sound moves about 4.3 times faster there.
Musically, 585 Hz is 7 cents below D5 (587.33 Hz) in standard A440 tuning. Doubling it to 1,170 Hz raises the pitch by one octave; halving it to 292.5 Hz lowers it by one.
