What does 3,500 Hz sound like?
3,500 Hz is a upper midrange frequency. It is a bright, penetrating tone in the region where human hearing is most sensitive – the reason alarms, whistles and baby cries live here.
A 3,500 Hz sound wave completes 3,500 cycles every second, so one cycle lasts 286 µs. In air at 20 °C, where sound travels at about 343 m/s, each wave is 9.8 cm (3.86 in) long; in water it stretches to 42.3 cm because sound moves about 4.3 times faster there.
Musically, 3,500 Hz is 10 cents below A7 (3.52 kHz) in standard A440 tuning. Doubling it to 7,000 Hz raises the pitch by one octave; halving it to 1,750 Hz lowers it by one.
