What does 3,100 Hz sound like?
3,100 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 3,100 Hz sound wave completes 3,100 cycles every second, so one cycle lasts 323 µs. In air at 20 °C, where sound travels at about 343 m/s, each wave is 11.1 cm (4.36 in) long; in water it stretches to 47.8 cm because sound moves about 4.3 times faster there.
Musically, 3,100 Hz is 20 cents below G7 (3.136 kHz) in standard A440 tuning. Doubling it to 6,200 Hz raises the pitch by one octave; halving it to 1,550 Hz lowers it by one.
