At St. Paul's Cathedral in London, a section of the dome called the Whispering Gallery makes a whisper audible from the other side of the dome as a result of the way sound waves travel around the curved surface. Researchers at Washington University in St. Louis have used the same phenomenon to build an optical device that may lead to new and more powerful computers that run faster and cooler. Lan Yang, PhD, associate professor of electrical and systems engineering, and her collaborators...

First Phononic Crystal That Can Be Altered In Real Time Announced By Researchers
2014-04-01 15:19:08

University of Bristol Using an acoustic metadevice that can influence the acoustic space and can control any of the ways in which waves travel, engineers have demonstrated, for the first time, that it is possible to dynamically alter the geometry of a three-dimensional colloidal crystal in real time. The colloidal crystals designed in the study, called metamaterials, are artificially structured materials that extend the properties of existing naturally occurring materials and...

Schematic of the detector: the metamaterial couples the incident light to the semiconductor, and then it can be converted into an electric signal
2014-03-30 06:26:20

Florian Aigner, Vienna University of Technology A new, extremely thin kind of light detector was created at Vienna University of Technology. Two very different technologies were combined for the first time: metamaterials and quantum cascade structures. Subtle interactions of electrons and light make them so valuable for technology: ultra-thin systems of semiconductor layers can turn electrical voltage into light. But they can also be used the other way around and serve as light...

Alligator Sound Perception Comes From Air-Filled Canals Between Their Ears
2014-03-28 09:21:20

Brett Smith for redOrbit.com - Your Universe Online For an animal without external ears, alligators have a strong sense of directional hearing and a new study published on Wednesday in the Journal of Experimental Biology has revealed that the reptiles’ refined hearing is a result of large, air-filled canals connecting two middle ears. "Mammals usually have large moveable ears, but alligators do not, so they have solved the problems of sound localization a little differently,” said...

A tuning fork, formed of a two-pronged fork, is an acoustic resonator with prongs formed from a U-shaped bar of elastic metal. When struck against a surface it resonates at a specific constant pitch emitting a pure musical tone after waiting a moment for some high overtones to die out. The length of the prongs determines the particular pitch of the fork. Most of the time it is used as a standard of pitch to tune other musical instruments. In 1711, John Shore invented the tuning fork. The...
