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 7,300 Hz sound like?
7,300 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 7,300 Hz sound wave completes 7,300 cycles every second, so one cycle lasts 137 µs. In air at 20 °C, where sound travels at about 343 m/s, each wave is 4.7 cm (1.85 in) long; in water it stretches to 20.3 cm because sound moves about 4.3 times faster there.
Musically, 7,300 Hz is 37 cents below A♯8 (7.459 kHz) in standard A440 tuning. Doubling it to 14,600 Hz raises the pitch by one octave; halving it to 3,650 Hz lowers it by one.
