Ventriloquist delight: Scientists twist sound with metamaterials so sound appears to come from somewhere else

A Chinese-U.S. research team is exploring the use of metamaterials — artificial materials engineered to have exotic properties not found in nature — to create devices that manipulate sound in versatile and unprecedented ways. They now report a simple design for a device, called an acoustic field rotator, which can twist wave fronts inside it so that they appear to be propagating from another direction.
