Caltech Engineers Develop One-way Transmission System for Sound Waves
July 26, 2011
While many hotel rooms, recording studios and even some homes are built with materials to help absorb or reflect sound, mechanisms to truly control the direction of sound waves are still in their infancy. However, researchers at the California Institute of Technology have now created the first tunable acoustic diode--a device that allows acoustic information to travel only in one direction, at controllable frequencies.
