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 2,000 Hz sound like?
2,000 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 2,000 Hz sound wave completes 2,000 cycles every second, so one cycle lasts 500 µs. In air at 20 °C, where sound travels at about 343 m/s, each wave is 17.2 cm (6.75 in) long; in water it stretches to 74.1 cm because sound moves about 4.3 times faster there.
Musically, 2,000 Hz is 21 cents above B6 (1.976 kHz) in standard A440 tuning. Doubling it to 4,000 Hz raises the pitch by one octave; halving it to 1,000 Hz lowers it by one.

Harmonics and octaves
Real instruments playing 2,000 Hz also produce harmonics at whole-number multiples of the fundamental. Their relative strength gives each instrument its timbre.
