Nissan is showing a new material at this year’s CES Show - Dave 😏

The Nissan company says will help make car cabins quieter while also boosting energy efficiency. Nissan started its research on acoustic meta-material technology more than a decade ago in 2008. At the time, meta-material was used in high-sensitivity antennas used for electromagnetic wave research. Nissan idea is to expand the scope of meta-material technology to include sound waves, leading to the successful invention of acoustic meta-material.
The new material is a combination of a lattice structure and plastic film, which together control air vibrations to limit the transmission of wide frequency band noise (500-1200 hertz), such as road and engine noise. Currently, automakers block this frequency band using heavy rubber boards. Nissan’s new acoustic meta-material weighs one-fourth as much as these while providing the same degree of sound isolation. Nissan claims the material’s simple structure lets them keep its cost competitive.
