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.
Read moreIs 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.
Read moreIs 500 Hz high or 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.
Read moreWhat Hz is too low?
Human reactions. 20 Hz is considered the normal low-frequency limit of human hearing.
Read moreHow do you determine low frequency sound?
Low frequency noise is typically perceived as a low throbbing, beating, rumbling, or even as a pressure on the ears . A person’s response to low frequency noise can also be quite individual due to differences in the frequency sensitivity of their hearing, which can vary considerably from person to person and with age.

Read moreWhat frequency is too low for humans?
Human beings can normally hear sounds with a frequency between about 20 Hz and 20,000 Hz. Sounds with frequencies below 20 hertz are called infrasound. Infrasound is too low-pitched for humans to hear.
