When sound hits an object, it makes distinct vibrations. "There's this very subtle signal that's telling you what the sound passing through is," said Abe Davis, a graduate student in electrical engineering and computer science at MIT and first author on the paper. But the movement is tiny - sometimes as small as thousandths of a pixel on video. It's only when all of these signals are averaged, Davis said, that you can extract sound that makes sense. By observing the entire object, you can filter out the noise. The results are certainly impressive (and a little scary). In one example shown in a compilation video, a bag of chips is filmed from 15 feet away, through sound-proof glass. The reconstructed audio of someone reciting "Mary Had a Little Lamb" in the same room as the chips isn't crystal clear. But the words being said are possible to decipher.Crazy, right? Unfortunately, I'm afraid this is actually some seriously bad news. You know why? "We're gonna have to start eating Pringles." EXACTLY. And I f***ing hate Pringles. Keep going for a video of the process in action.
