Phononic circuits are emerging devices that can manipulate sound waves (i.e., phonons) in ways that resemble how electronic circuits control the flow of electrons. Instead of relying on wires, ...

All audio systems, including those installed in , SUVs, and trucks are engineered to handle specific ranges of sound frequencies. These range differences explain why some speakers have slightly ...

Researchers at Uppsala University have created the first 3D map of the hearing nerve showing where the various sound frequencies are captured. Using what is known as synchrotron X-ray imaging, they ...
