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 715 Hz sound like?
715 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 715 Hz sound wave completes 715 cycles every second, so one cycle lasts 1.4 ms. In air at 20 °C, where sound travels at about 343 m/s, each wave is 48.0 cm (1.57 ft) long; in water it stretches to 2.07 m because sound moves about 4.3 times faster there.
Musically, 715 Hz is 41 cents above F5 (698.46 Hz) in standard A440 tuning. Doubling it to 1,430 Hz raises the pitch by one octave; halving it to 357.5 Hz lowers it by one.
