It is known that the human body can generate mechanical vibrations at very low frequencies , so-called infrasonic waves. Such low-frequency vibrations are produced by physiological processes—heartbeats, respiratory movements, blood flow in vessels, and other processes.

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.
Read moreWhat range of frequencies can humans make?
Humans can detect sounds in a frequency range from about 20 Hz to 20 kHz . (Human infants can actually hear frequencies slightly higher than 20 kHz, but lose some high-frequency sensitivity as they mature; the upper limit in average adults is often closer to 15–17 kHz.)

During a conversation, the fundamental frequency of a typical adult man ranges from 80 to 180 Hz and that of a typical adult woman from 165 to 255 Hz. Thus, if we look at these three images, the fundamental frequency of most speech falls below the lower edge of the “speech frequency band.”8 Tem 2020

Consequently, while the human audible frequency range extends up to about 15 kHz for most individuals and to 20 kHz for younger adults and children , the term “high frequency” in the speech and voice literature often refers to frequencies anywhere from 2 to 5 kHz (e.g., Hornsby and Ricketts, 2003), or, more rarely, up …16 Haz 2014
