Singing Sand Dunes
It has been known that some sand dunes have the peculiar ability of emitting a loud sound with a well defined frequency, sometimes for several minutes. The origin of this sustained sound has remained mysterious, partly because of its rarity in nature.
Host Aaron Schachter of “TheWorld.org” finds out what makes a sand dune sing. He speaks with French physicist Stéphane Douady, who’s compiling a CD of tunes from the dunes pulled from his research on sounds made by the hills of sand.

Wow! That’s really cool. I’ve heard of this before, but I never knew why it happened. I still don’t get it exactly, but its very interesting. Another mystery of the world.

Actually, the mystery is what role the coating of some grains of sand has on pitch and the resisting of wave-creation.

actually… if anyone finds tracks that have the noise being made… let me know where they are at, I’d love to hear more about this.

They’re linked in the post, above. They can be heard in the interview link, and a video of how they produced the sounds can be found on the Frenchman’s website.
