If you happen to be one who loves to eavesdrop, then here is one interesting device that you might be interested in – researchers over at the University of Texas at Austin have managed to come up with an acoustic isolator device. This particular acoustic isolator device allows you to hear what others are saying, and yet it will also prevent them from hearing you. Known as a one-way acoustic circulator, the concept behind this idea is pretty simple despite breaking a basic law of physics along the way, where sound waves travel in one direction and must travel in the opposite direction.
