What does 2,950 Hz sound like?
2,950 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 2,950 Hz sound wave completes 2,950 cycles every second, so one cycle lasts 339 µs. In air at 20 °C, where sound travels at about 343 m/s, each wave is 11.6 cm (4.58 in) long; in water it stretches to 50.2 cm because sound moves about 4.3 times faster there.
Musically, 2,950 Hz is 6 cents below F♯7 (2.96 kHz) in standard A440 tuning. Doubling it to 5,900 Hz raises the pitch by one octave; halving it to 1,475 Hz lowers it by one.
