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 695 Hz sound like?
695 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 695 Hz sound wave completes 695 cycles every second, so one cycle lasts 1.44 ms. In air at 20 °C, where sound travels at about 343 m/s, each wave is 49.4 cm (1.62 ft) long; in water it stretches to 2.13 m because sound moves about 4.3 times faster there.
Musically, 695 Hz is 9 cents below F5 (698.46 Hz) in standard A440 tuning. Doubling it to 1,390 Hz raises the pitch by one octave; halving it to 347.5 Hz lowers it by one.
