WHAT ARE INFRASOUNDS?
Infrasound are waves of sound at frequencies below 20 Hertz. A human can’t hear those sounds. Sounds at those frequencies are faint to the human ear.
An important aspect of infrasonic sound is that it travels extended distances. Natural phenomenon such as storms and earthquakes can produce infrasonic sounds.
