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 13,400 Hz sound like?
13,400 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 13,400 Hz sound wave completes 13,400 cycles every second, so one cycle lasts 74.6 µs. In air at 20 °C, where sound travels at about 343 m/s, each wave is 2.6 cm (1.01 in) long; in water it stretches to 11.1 cm because sound moves about 4.3 times faster there.
Hearing at these frequencies declines steadily with age (presbycusis) and with noise exposure. If you cannot hear this tone, check that your headphones can reproduce it before drawing conclusions – and try our hearing test for a playful estimate.
