What is considered low Hz?

Low-frequency sounds are 500 Hz or lower while high-frequency waves are above 2000 Hz. Human ears can register sounds from about 20 Hz in frequency up to 20,000 Hz, depending of course, upon the hearer. People with hearing loss usually have trouble hearing sounds in the higher frequency range.6 Eki 2017

Is 7 Hz low-frequency?

Especially dangerous is infrasound at the frequency of 7 Hz , since this sound, generating frequencies, close to characteristic frequencies of the organs of our body, may disturb the heart or brain activity. Machines, natural sources storms, earthquakes, hurricanes, etc. generate infrasound.

Is 20 Hz high or low?

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.
