In a new preprint study, researchers at Carnegie Mellon University claim sound can be used to predict an object's appearance -- and its motion. The coauthors created a "sound-action-vision" data set ...

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 ...

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 ...

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 ...

Researchers at the University of Bristol have been able to levitate objects using ultrasonic waves larger than the wavelengths of sound used by the device. This could enable touchless control of drug ...

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 ...

This video shows a real live tractor beam in action. It uses an array of small speakers to levitate objects and to move them precisely through the air. The beam can even pull objects from above, just ...

Tokyo, Japan - Researchers from Tokyo Metropolitan University have developed a new technology which allows non-contact manipulation of small objects using sound waves. They used a hemispherical array ...

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 ...
