Infrasound, sometimes referred to as low status sound , describes sound waves with a frequency below the lower limit of human audibility (generally 20 Hz). Hearing becomes gradually less sensitive as frequency decreases, so for humans to perceive infrasound, the sound pressure must be sufficiently high.
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.

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.
