3,450 Hz tone

Play a 3,450 Hz tone online, see what note it is, how long its wave is and which animals can hear it. It is a bright, penetrating tone in the region where human hearing is most sensitive – the reason alarms, whistles and baby cries live here.

What does 3,450 Hz sound like?

3,450 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 3,450 Hz sound wave completes 3,450 cycles every second, so one cycle lasts 290 µs. In air at 20 °C, where sound travels at about 343 m/s, each wave is 9.9 cm (3.91 in) long; in water it stretches to 42.9 cm because sound moves about 4.3 times faster there.

Musically, 3,450 Hz is 35 cents below A7 (3.52 kHz) in standard A440 tuning. Doubling it to 6,900 Hz raises the pitch by one octave; halving it to 1,725 Hz lowers it by one.
