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 700 Hz sound like?
700 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 700 Hz sound wave completes 700 cycles every second, so one cycle lasts 1.43 ms. In air at 20 °C, where sound travels at about 343 m/s, each wave is 49.0 cm (1.61 ft) long; in water it stretches to 2.12 m because sound moves about 4.3 times faster there.
Musically, 700 Hz is almost exactly F5 (698.46 Hz) in standard A440 tuning. Doubling it to 1,400 Hz raises the pitch by one octave; halving it to 350 Hz lowers it by one.
