What does infrasound mean?
Infrasound refers to sound waves with frequencies lower than 20 Hz, which are below the normal range of human hearing. These low-frequency sounds can be generated by natural phenomena such as earthquakes, volcanic eruptions, and ocean waves. Infrasound is used in various scientific applications, including monitoring seismic activity, tracking volcanic eruptions, and studying ocean currents. The detection of infrasound waves can provide valuable information about the source and characteristics of these events. Infrasound research has also explored its potential uses in fields such as meteorology and glaciology. Overall, infrasound is an important area of study that helps us better understand the Earth's physical environment.

Etymology of infrasound
The term 'infrasound' was coined by combining the prefix 'infra-', meaning 'below' or 'under', with the word 'sound'. This refers to the fact that infrasound waves have frequencies below the range of human hearing. The word 'infrasound' originated in the mid-20th century, as scientists began to study and detect these low-frequency sound waves.
Usage notes
Infrasound is often used in scientific and research contexts to study natural phenomena and monitor environmental changes.
