What does 4,250 Hz sound like?
4,250 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 4,250 Hz sound wave completes 4,250 cycles every second, so one cycle lasts 235 µs. In air at 20 °C, where sound travels at about 343 m/s, each wave is 8.1 cm (3.18 in) long; in water it stretches to 34.8 cm because sound moves about 4.3 times faster there.
Musically, 4,250 Hz is 26 cents above C8 (4.186 kHz) in standard A440 tuning. Doubling it to 8,500 Hz raises the pitch by one octave; halving it to 2,125 Hz lowers it by one.
