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 963 Hz sound like?
963 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 963 Hz sound wave completes 963 cycles every second, so one cycle lasts 1.04 ms. In air at 20 °C, where sound travels at about 343 m/s, each wave is 35.6 cm (1.17 ft) long; in water it stretches to 1.54 m because sound moves about 4.3 times faster there.
Musically, 963 Hz is 44 cents below B5 (987.77 Hz) in standard A440 tuning. Doubling it to 1,926 Hz raises the pitch by one octave; halving it to 481.5 Hz lowers it by one.
