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 ...

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 ...

In laboratories from Brazil to Munich, researchers are learning to grab matter with sound alone, sculpting ultrasonic waves into invisible “hands” that can lift, push, and rotate objects without a ...

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 ...

Although their technique employs a method similar to laser trapping in biology, adaptable to a wider range of particle sizes and materials. The ability to move objects without touching them might ...

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 ...
