"Such an acoustic veil would do for sound what the "invisibility cloak" previously demonstrated by the research team does for microwaves--allowing sound waves to travel seamlessly around it and emerge on the other side without distortion (http://www.pratt.duke.edu/news/?id=792)."

"Cummer wasn't convinced. "In my mind, waves are waves," he said. "It was hard for me to imagine that something you could do with electromagnetic waves would be completely undoable for sound waves.""
Oil is oil.
I have no idea if this could apply to sonic booms. Just thought I'd raise the question.

Electromagnetic radiation consists of photos, and travels through a medium. Sound waves are comprised of oscillations in the medium itself.

I have no idea if this could apply to sonic booms. Oh, it was my first thought as well. But on further thought...sound waves passing harmlessly around an aircraft is different than the air that is displaced which creates a shockwave.
Now, if a material can be produced that does the same for radar energy. Whooppeee!
