What does 4,150 Hz sound like?
4,150 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 4,150 Hz sound wave completes 4,150 cycles every second, so one cycle lasts 241 µs. In air at 20 °C, where sound travels at about 343 m/s, each wave is 8.3 cm (3.25 in) long; in water it stretches to 35.7 cm because sound moves about 4.3 times faster there.
Musically, 4,150 Hz is 15 cents below C8 (4.186 kHz) in standard A440 tuning. Doubling it to 8,300 Hz raises the pitch by one octave; halving it to 2,075 Hz lowers it by one.
