2014-03-12 12:14:17

Lee Rannals for redOrbit.com - Your Universe Online Engineers at Duke University have demonstrated the world’s first three-dimensional acoustic cloaking device. The scientists reported in the journal Nature Materials that they have created a new device that reroutes sound waves to create the impression that the cloak and whatever it covers is not there. This technology could one day be used by the US Navy as a way to avoid sonar detection. According to the researchers, the acoustic...

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...
