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 ...

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 ...

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 ...

Levitation is often thought of as the realm of magicians or The Jetsons, but it is technically possible. That said, the tech seems to be moving pretty slowly. Now, researchers at the University of ...

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 ...

Duke University researchers invent a cloak-like structure that could be used to improve everything from defense technology to acoustics in concert halls. Technology for an invisibility cloak hasn’t ...

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 ...

Researchers in Switzerland have found a way of using sound waves to manipulate objects in disordered environments such as liquids. Instead of trapping the objects as conventional optical and acoustic ...

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 ...
