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 6,600 Hz sound like?
6,600 Hz is a brilliance (air) frequency. It is a very high, thin, whistling tone. Sensitivity in this region falls with age, so younger listeners hear it much more clearly than older ones.
A 6,600 Hz sound wave completes 6,600 cycles every second, so one cycle lasts 152 µs. In air at 20 °C, where sound travels at about 343 m/s, each wave is 5.2 cm (2.05 in) long; in water it stretches to 22.4 cm because sound moves about 4.3 times faster there.
Musically, 6,600 Hz is 12 cents below G♯8 (6.645 kHz) in standard A440 tuning. Doubling it to 13,200 Hz raises the pitch by one octave; halving it to 3,300 Hz lowers it by one.
