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 765 Hz sound like?
765 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 765 Hz sound wave completes 765 cycles every second, so one cycle lasts 1.31 ms. In air at 20 °C, where sound travels at about 343 m/s, each wave is 44.8 cm (1.47 ft) long; in water it stretches to 1.94 m because sound moves about 4.3 times faster there.
Musically, 765 Hz is 42 cents below G5 (783.99 Hz) in standard A440 tuning. Doubling it to 1,530 Hz raises the pitch by one octave; halving it to 382.5 Hz lowers it by one.
