Infrasound

Infrasound is basically a sound that is too low for humans to hear. Sounds like a car engine, music or people talking are made up of vibrations that travel through the air and into our ears. But infrasound is like a secret sound that only some animals can hear, like elephants or whales.

Have you ever seen a wave in the ocean? Well, sound is kind of like that wave. It goes up and down and makes a noise. But infrasound has a much longer wave than we can see or hear, because it is way too low for our ears to pick up. Think of it like a giant whale call that travels really far, but we can’t hear it because it’s underwater and too low for us.

Scientists are interested in infrasound because it can tell us about things we can’t see or hear, like earthquakes, volcanoes or even rockets launching into space! They use special machines, called microphones, to pick up these infrasounds and then they can study them to learn more about these things.

So, in summary, infrasound is a low sound that animals can hear but humans cannot, and it can tell us about things that are beyond our senses.
