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 755 Hz sound like?
755 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 755 Hz sound wave completes 755 cycles every second, so one cycle lasts 1.32 ms. In air at 20 °C, where sound travels at about 343 m/s, each wave is 45.4 cm (1.49 ft) long; in water it stretches to 1.96 m because sound moves about 4.3 times faster there.
Musically, 755 Hz is 35 cents above F♯5 (739.99 Hz) in standard A440 tuning. Doubling it to 1,510 Hz raises the pitch by one octave; halving it to 377.5 Hz lowers it by one.
