A few days ago I came across a small article in a recent newspaper about using "meta-materials" to cloak sound waves much in the same way as making something visual invisible. If this process was employed in speaker design would it prevent sound waves from bouncing around inside the cabinet? Would it mean the end of acoustic tiles and other room treatments? Imagine the possibilities!
