Wearing noise-canceling headphones around everywhere certainly affords you some silence but you’d appear a bit anti-social. Wearing a noise-canceling cloak, on the other hand, would probably make you appear a bit crazy.

In fact, the cloak works much like the oft-ruminated invisibility cloak in also canceling out the sounds made by the person wearing it. Made from stacked sheets of plastic peppered with holes, its structure and size redirects sound waves.
