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.
Read moreCan you hear below 20hz?
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.)

Low Midrange : 250 to 500 Hz The low midrange contains the low order harmonics of most instruments and is generally viewed as the bass presence range. Boosting a signal around 300 Hz adds clarity to the bass and lower-stringed instruments. Too much boost around 500 Hz can make higher-frequency instruments sound muffled.25 Nis 2020
Read moreWhat is the lowest Hz A human can make?
The human ear can hear frequencies up to 20kHz but we can’t scream higher than 3kHz or so. The bottom end of our hearing range is 20Hz , which is still just below the deepest notes that most of us normally make (around 85Hz).
Read moreIs 500 Hz a low-frequency?
Frequency is measured in hertz (Hz) [hurts]. A low- frequency sound is about 500 Hz or lower. A high- frequency sound is about 2,000 Hz and higher.

Sounds around 19 hz, matches the resonant frequency of the human eyeball, with reports of apparitions as detailed by the Coventry Telegraph newspaper. The most dangerous frequency is at the median alpha-rhythm frequencies of the brain, 7 hz . This is also the resonant frequency of the body’s organs.
