infrasonics, vibrational or stress waves in elastic media, having a frequency below those of sound waves that can be detected by the human ear —i.e., below 20 hertz. The range of frequencies extends down to geologic vibrations that complete one cycle in 100 seconds or longer.
Read moreWhat are low-frequency sounds called?
Sounds with a frequency of 20 Hz and lower are called infrasound . Low frequency sound is understood to mean sound, the frequency of which is below 125 Hz. Infrasound and low frequency sound are difficult to hear, but they cannot be called completely inaudible.
Read moreWhat are low-frequency sounds used for?
At the other end of the spectrum are very low-frequency sounds (below 20 Hz), known as infrasound. Elephants use infrasound for communication , making sounds too low for humans to hear. Because low frequency sounds travel farther than high frequency ones, infrasound is ideal for communicating over long distances.3 Tem 2018
Read moreCan humans hear low-frequency sounds?
Sound at 20-200 Hz is called low-frequency sound, while for sound below 20 Hz the term infrasound is used. The hearing becomes gradually less sensitive for decreasing frequency, but despite the general understanding that infrasound is inaudible, humans can perceive infrasound, if the level is sufficiently high .

Healthy young adults should be able to hear frequencies anywhere between 20 and 20.000 Hz . The most important frequencies for speech and language are between 250 and 8000 Hz.
