EPFL researchers have developed a 100% effective, ultra-thin active noise cancelling system that uses an ionized air plasma propulsion system instead of speakers. A 17-mm-thick (0.6-in) layer can ...

Did you know that wires can be used to ionize air to make a loudspeaker? Simply put, it’s possible to generate sound by creating an electric field in a set of parallel wires, aka a plasma transducer, ...

Finding could have applications in acoustic-levitation-assisted 3D printing, mid-air chemical synthesis and micro-robotics ...

Earlier this year, Dyson revealed its first audio product, a pair of headphones that promised to not only block noise, but unwanted airborne particles as well, thanks to a built-in filtration system ...

Levoit air purifiers come with an advanced filtration system in different layers which helps in the capturing of minute ...

In Delhi these days, it feels like bad air has become normal. On days when pollution spikes and the Air Quality Index goes off the charts, even stayin.

Scientists show that a thin layer of plasma, created by ionizing air, could be promising as an active sound absorber, with applications in noise control and room acoustics. Did you know that wires can ...
