it refers to the sound waves that are below the frequency of audible range of hearing
it includes anything under 20Hz
example volcanoes, earthquake, meteorites etc

Sound with a frequency less than 20 hertz, Hz, is known as infrasound. This is below the range that humans can hear (usually between 20-20 000Hz). Infrasound is detected using a microphone. Infrasound has many uses.
Elephants and giraffes use infrasound to communicate between herds over long distances. Scientists can now use microphones to track the herds even if they are hidden in dense forests. This helps with the conservation and protection of these animals.

Infrasound can be used to detect volcanic eruptions. As a volcano erupts it produces infrasound, which can be detected even if the volcano is in a remote location a long way away. Scientists also use infrasound to track the passage of meteors through the atmosphere. Meteors are lumps of rock from space. Most burn up in the atmosphere but some hit earth. If a meteor hit a populated area it could cause considerable damage.
