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 ...

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 ...

Norris, a distinguished professor in the Department of Mechanical and Aerospace Engineering at Rutgers University-New Brunswick, is developing honeycomb-like metallic structures that reroute sound ...

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 ...
