Nissan shows new, lightweight noise-reducing technology Weighing around one-fourth of conventional sound insulation materials, Nissan’s acoustic meta-material delivers both quietness and efficienct. It is a combination of a lattice structure and plastic film controls air vibrations to limit the transmission of wide frequency band noise (500-1200 hertz), such as road and engine noise. Currently, most materials used to isolate this frequency band consist mainly of heavy rubber board.

Nissan started its research on meta-material technology around 2008. At the time, meta-material was used in high-sensitivity antennas used for electromagnetic wave research. Nissan worked to extend the applicability of meta-material technology to include sound waves, leading to the successful invention of acoustic meta-material. Making vehicles lighter helps limit the environmental impact of driving by improving energy efficiency. It also enhances enjoyment, as the quiet vehicle cabin makes driving more comfortable.

A Nissan innovation that can help make cars quieter and more energy efficient has won an award from Popular Science - Dave 😉

“The noise-reducing technology, known as acoustic meta-material, received a 2020 Popular Science Best of What’s New Award in the automotive category. Nissan’s acoustic meta-material is a new lightweight sound insulation material. Its makeup is simple: A combination of a lattice structure and plastic film controls air vibrations to limit the transmission of wide frequency band noise (500-1200 hertz), such as road and engine noise. While most materials used to isolate this frequency band consist mainly of heavy rubber board, Nissan’s acoustic meta-material is one-fourth the weight yet provides the same degree of sound isolation.”
