Forget superconductors and magnetic fields. Scientists from the University of Tokyo have developed a way to use sound waves to levitate objects and move them around midair. When a sound wave travels ...

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 ...

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 ...

Additive manufacturing or 3D printing enables the fabrication of complex parts from functional or biological materials. Conventional 3D printing can be a slow process, where objects are constructed ...

It’s possible to defy gravity using sound waves, magnets or electricity, but today’s methods can’t hoist heavy items high in ...

Tractor beams have hit the big time. A newly constructed device generates a beam of concentrated sound that, for the first time, exerts a continuous, perceptible tug on objects large enough to see.

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 ...

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 ...

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 ...

These are the sorts of things Dennis Paul asked himself, before he built An Instrument for the Sonification of Everyday Things. The machine itself is basically a large spit, rotating any object ...

Leonardo Music Journal, Vol. 23, Sound Art (2013), pp. 65-69 (5 pages) This his paper defines the objectbased sound installation as a distinct category of sound art that emerges from the intersection ...
