The Sound of Booming Sands Around the World

Despite geographical differences or differences in the sand itself, the actual way the booming sand offerates is the same. Say i were to go and get sand from like, a random beach, would it be able to make this booming sound if if i could somehow set it up in the right configuration? You'd have to have a long channel. And then what we found is that below this real dry layer probably probably retains some moisture at some depth. It gets a lot harder as e dry, kind of above a hard layer that allows the wave to be reflected off that inner face between the dry and the hard.
