There is this zoo of infrasound out there.

And most of it we're familiar with.

And then there's all these exotic creatures out there.

Some of them are known, but reemerge out of hiding occasionally.

And some of them have not been heard in a very long time.

And when they do emerge, you don't recognize them.

Oh my goodness, one of my favorite sounds, which is so deep that I have failed repeatedly to try to insonify it, is the sound from the 2022 eruption in Tonga.

We hadn't heard a sound like that in over a century since Krakatoa.

And when it came up, we have a whole generation of scientists that only knew this signature from the lore of it, you know, written in like Royal Society journals, right?

And to see them from...

old, tiny paper scratches to recording it digitally, in full digital glory, recorded as it goes all around the world.

We hadn't seen that in centuries.

So for us, it was a moment of awe.

Is this what I really think it is?

Oh, it's everywhere.

You first perceive it in your heartbeat of your mother, you know.

If you're sitting there breathing, even walking, a lot of our biorhythms are infrasonic in nature.

But we kind of, we're just used to them, right?

Even at deeper level, you know, the sound of the ocean, it contains massive amounts of infrasound, right?

The air moving around us.
