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

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 ...

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.

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 ...

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 ...

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 ...

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 ...

Researchers in Tokyo have put a new twist on the use of sound to suspend objects in air. They've used ultrasonic standing waves to trap pieces of wood, metal, and water – and even move them around.

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 ...

Researchers recently created an acoustic hologram, or a 3D sound field projected onto a 2D space, which can be used as acoustic tweezers, cages and twisters that manipulate objects as they levitate in ...
