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 785 Hz sound like?
785 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 785 Hz sound wave completes 785 cycles every second, so one cycle lasts 1.27 ms. In air at 20 °C, where sound travels at about 343 m/s, each wave is 43.7 cm (1.43 ft) long; in water it stretches to 1.89 m because sound moves about 4.3 times faster there.
Musically, 785 Hz is almost exactly G5 (783.99 Hz) in standard A440 tuning. Doubling it to 1,570 Hz raises the pitch by one octave; halving it to 392.5 Hz lowers it by one.
