Start with your device volume low. Very low tones may be inaudible on phone or laptop speakers; very high tones can be uncomfortable on headphones.
What does 2,500 Hz sound like?
2,500 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 2,500 Hz sound wave completes 2,500 cycles every second, so one cycle lasts 400 µs. In air at 20 °C, where sound travels at about 343 m/s, each wave is 13.7 cm (5.40 in) long; in water it stretches to 59.2 cm because sound moves about 4.3 times faster there.
Musically, 2,500 Hz is 8 cents above D♯7 (2.489 kHz) in standard A440 tuning. Doubling it to 5,000 Hz raises the pitch by one octave; halving it to 1,250 Hz lowers it by one.
