Apparently not substance with simply building an invisibility cloak, of sorts, those mad scientists at Duke University’s Pratt School of Engineering now say that they’ve found that a three-dimensional “sound cloak” is additionally possible, in theory. According to Duke’s Steven Cummer, the researchers have come up with a “recipe” for an acoustic material that would “essentially open up a gap in space and form

something inside that gap vanish from sound waves.” Needless to say, they haven’t tested that possibility just yet, but they say it could one day be used to hide submarines from detection by sonar or even be used to improve the acoustics of a concert hall by making inconvenient structural beams effectively vanish. What’s more, they say that the basic principles at play here could additionally propose […]
