What does 3,600 Hz sound like?
3,600 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 3,600 Hz sound wave completes 3,600 cycles every second, so one cycle lasts 278 µs. In air at 20 °C, where sound travels at about 343 m/s, each wave is 9.5 cm (3.75 in) long; in water it stretches to 41.1 cm because sound moves about 4.3 times faster there.
Musically, 3,600 Hz is 39 cents above A7 (3.52 kHz) in standard A440 tuning. Doubling it to 7,200 Hz raises the pitch by one octave; halving it to 1,800 Hz lowers it by one.
