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 14 Hz sound like?
14 Hz is a infrasound frequency. It is infrasound – below the roughly 20 Hz lower limit of human pitch perception. At high levels it is felt as pressure, fluttering or vibration rather than heard as a tone, and phone or laptop speakers cannot reproduce it at all.
A 14 Hz sound wave completes 14 cycles every second, so one cycle lasts 71.4 ms. In air at 20 °C, where sound travels at about 343 m/s, each wave is 24.50 m (80.38 ft) long; in water it stretches to 105.79 m because sound moves about 4.3 times faster there.
Natural infrasound comes from earthquakes, volcanoes, ocean waves, wind and thunder; whales and elephants use it to communicate across long distances.

Harmonics and octaves
Real instruments playing 14 Hz also produce harmonics at whole-number multiples of the fundamental. Their relative strength gives each instrument its timbre.

Frequently asked questions
What does 14 Hz sound like?
It is infrasound – below the roughly 20 Hz lower limit of human pitch perception. At high levels it is felt as pressure, fluttering or vibration rather than heard as a tone, and phone or laptop speakers cannot reproduce it at all.
Can humans hear 14 Hz?
No. 14 Hz is below the ~20 Hz limit of human pitch perception; very loud infrasound can be felt as vibration.
What musical note is 14 Hz?
14 Hz is 31 cents above A-1, which is 13.75 Hz in standard A440 tuning.
What is the wavelength of 14 Hz?
About 24.50 m in air at 20 °C and 105.79 m in water.
Can dogs hear 14 Hz?
No – dogs hear roughly 67 Hz to 45,000 Hz.
