Infrasounds are useful because they can travel long distances and penetrate obstacles, making them ideal for communication, navigation, and detection purposes. They are also less affected by weather conditions and background noise compared to higher frequency sounds. Additionally, infrasounds can be used for monitoring natural phenomena such as earthquakes and volcanic eruptions.

Why are infrasounds more useful more useful than sound for detecting volcanic eruptions?

Additionally, infrasounds can detect eruptions even when visibility is poor or when the eruption is not visually observable.
What are Frequencies below 20 Hz?
