How the ambient sound at Walt Disney World works

[Towncrier]

I ran across this very interesting article (for Disney Geeks) on boingboing.net this morning and wanted to share:

An interview with the man who designed the ambient sound at Disney World, ensuring a constant experience rather than one that ends with the end of the ride. It was initially a little uneven, with sound changing volumes depending on where you stood, so they used algorithms to position 15,000 speakers around the park so that the levels would never change.
