Scientists have developed a new 'Bond-Style' device that may allow spies to listen to someone without having to worry about being heart.
Researchers at the University of Texas at Austin's Cockrell school of engineering have built the first ever non-reciprocal Circulator sound that is able to break sound wave reciprocity. Experiments with the device successfully prove that the fundamental symmetry with which acoustic waves travel through air between two pints in space can be broken by a compact and simple device. "Using the proposed concept, we were able to create one-way communication for sound travelling through air".
