Active noise control (ANC) systems utilise advanced signal processing techniques to generate anti-noise signals that effectively cancel unwanted sound. These systems combine acoustic theory with ...

Engineers are not just adding more insulation, they are reinventing how interior noise is captured, modeled, and judged so ...

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 ...

The most obvious way to get rid of ambient noise is to employ some form of passive or active noise cancellation (ANC). The type of ANC we’re familiar with today was coined in 1989 by Dr. Amar Bose ...

The world is getting louder. People cannot escape noise pollution in their everyday lives whether from traffic, infrastructure, music or more, but employees can and must be protected from excessive ...

Follow the science to understand how passive noise blocking and noise-masking audio create a truly restful environment.

Headphone brands like Sony, JBL, Bose, Sonos and Sennheiser offer a good selection of premium noise cancelling headphones ...

Why does cancer sometimes recur after chemotherapy? Why do some bacteria survive antibiotic treatment? In many cases, the ...
