Engineers have demonstrated the world's first three-dimensional acoustic cloak. The new device reroutes sound waves to create the impression that the cloak and anything beneath it are not there. The ...

Sound! It’s a thing you hear, moreso than something you see with your eyes. And yet, it is possible to visualize sound with ...

Thermoacoustic devices harness rapid, periodic heating to drive oscillations in a surrounding fluid, thereby generating acoustic waves without the need for conventional moving parts. This technology ...

Acoustics encompasses the study of mechanical waves that propagate through media, a field that underpins a diverse array of technologies from noise control and ultrasonics to acousto‐optic modulation.

A team of scientists used playbacks of recorded and artificial porpoise clicks to develop an adaptable method to assess the area in which acoustic monitoring devices can reliably detect these sounds ...

When graphene was first synthesized, a lot of research went into investigating how it could be used in electronics, like FETs and memory. However, little research was done into the use of graphene in ...

Acoustic lenses are remarkable devices that just got cooler. A recent presentation at SIGGRAPH 2019 showed that with the help of 3D printing, it is possible to build the acoustic equivalent of optical ...

Scientists identify two sound-driven mechanisms for generating orbital currents, merging acoustics with cutting-edge electron physics. (Nanowerk News) Electronics traditionally rely on harnessing the ...

ToneWoodAmp loaned me their product to review — it's a small device that attaches to the back of an acoustic guitar to provide effects and amplification without plugging into a conventional amplifier.

DURHAM, N.C. -- Using little more than a few perforated sheets of plastic and a staggering amount of number crunching, Duke engineers have demonstrated the world's first three-dimensional acoustic ...
