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.

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 ...

While Sensitive Object sounds like a gift shop for ladies who love kitties and angels, it is, in fact, a French company that creates interface systems based on temporal reversal. Apparently if you tap ...

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 ...

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 ...

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 ...

Although movie and game producers can now create computer-animated images of just about anything, the sounds made by those onscreen items still typically consist of recordings of real-world objects.

Sound and object motion can be used to change perceptions about body size, according to a new study by an international team involving UCL researchers. Sound and object motion can be used to change ...

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 ...
