Infrasonic refers to sounds or vibrations with frequencies below the range of human hearing. These frequencies are too low for us to perceive them with our ears 〰️. Infrasonic waves can travel long distances and are often produced by natural events like earthquakes and volcanoes. Some animals, like elephants, use infrasonic communication. It's a hidden world of sound beyond our normal awareness.
'Infrasonic' is formed from the prefix 'infra-' (meaning 'below') and 'sonic' (relating to sound). It literally means 'below the range of sound.' The term became established in the field of acoustics and physics to describe these low-frequency phenomena. The 'infra-' prefix is also used in other words like 'infrared' (below red in the spectrum).
In the movie 'Jurassic Park,' the T-Rex's approach is heralded not by sound, but by vibrations. These are essentially infrasonic tremors. The characters feel the earth shake before they hear anything. This creates a sense of primal fear and anticipation. It's a great example of how infrasonic phenomena can impact us, even if we don't consciously hear them.
