What does 4,100 Hz sound like?
4,100 Hz is a presence frequency. It is a high, piercing whistle. The ear is still very sensitive here, so even quiet playback sounds loud.
A 4,100 Hz sound wave completes 4,100 cycles every second, so one cycle lasts 244 µs. In air at 20 °C, where sound travels at about 343 m/s, each wave is 8.4 cm (3.29 in) long; in water it stretches to 36.1 cm because sound moves about 4.3 times faster there.
Musically, 4,100 Hz is 36 cents below C8 (4.186 kHz) in standard A440 tuning. Doubling it to 8,200 Hz raises the pitch by one octave; halving it to 2,050 Hz lowers it by one.
