Researchers in the US have made a “carpet cloak” that makes objects invisible to sound waves. The device is the first such cloak to work in air and could be used to improve the acoustics in concert ...

It may seem straight out of "Star Trek," but it's real: Scientists have created a sonic "tractor beam" that can pull, push and pirouette objects that levitate in thin air. The sonic tractor beam ...

Amanda D. Hanford, at Pennsylvania State University, is taking the introductory steps to make acoustic ground cloaks. These materials redirect approaching waves around an object without scattering the ...

3D-printed motorcycle earmuffs that suppress traffic and wind noise while amplifying car horns, and objects encoded with unique audio barcodes are just a couple of the devices that could be on the way ...

The researchers were able to levitate and transport items ranging from a droplet of water to a toothpick. They did so using pairs of sound-emitting platforms and reflector sheets. Sound leaves the ...

A simple technique has been developed to achieve acoustic illusions — those that can trick the ear or a sound detector 1. The technique’s applications range from architectural acoustics to camouflage ...

Gene Roddenberry would be beaming with pride right now to see the scientific community hellbent on making his science fiction into science fact. Gene did actually get to see some of his ideas turn ...

A new "tractor beam" can levitate large objects in midair, using only sound. So far, researchers have floated spheres as large as 0.6 inches (16 millimeters) in diameter and moved orbs as large as 0.8 ...

U-tube: the glass tube and piezoelectric speaker that were used to create the new mass sensor. (Courtesy: William Grover) A $12 device that can measure the mass of microgram-sized objects in fluid has ...

Nick Brennan, a designer and maker living and working in London, has created a revolutionary new style of instrument called Sound Pegs. This innovative device allows you to transform everyday objects ...
