What does 2,250 Hz sound like?
2,250 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 2,250 Hz sound wave completes 2,250 cycles every second, so one cycle lasts 444 µs. In air at 20 °C, where sound travels at about 343 m/s, each wave is 15.2 cm (6.00 in) long; in water it stretches to 65.8 cm because sound moves about 4.3 times faster there.
Musically, 2,250 Hz is 25 cents above C♯7 (2.217 kHz) in standard A440 tuning. Doubling it to 4,500 Hz raises the pitch by one octave; halving it to 1,125 Hz lowers it by one.
