　　Recently, Nissan China’s official Weibo account announced that its newly developed lightweight, ultra‑quiet sound‑insulation material has been awarded the Best Innovation Award in the automotive category by Popular Science. This is an entirely new, lightweight, high‑performance sound‑proofing material.

　　In January this year, Nissan unveiled a new lightweight, ultra‑quiet sound‑insulating material at the 2020 International Consumer Electronics Show. According to the company, this innovative material not only enhances cabin quietness but also helps improve fuel efficiency.

　　According to reports, this material combines a crystalline structure with a plastic film, enabling it to effectively dampen airborne vibrations and reduce the transmission of broadband noise (500–1200 Hz) generated by vehicle motion on the road and by the engine. Currently, most sound‑insulating materials in this frequency range are made from heavy‑duty rubber.

　　Nissan stated that its new, state-of-the-art sound‑insulation material has been optimized for weight, achieving a 75% reduction compared with conventional materials—without compromising sound‑proofing performance.

　　Notably, the production cost of this new ultra‑high‑performance sound‑insulating material is nearly on par with that of conventional materials—and in some cases even more competitive. As a result, it is equally well suited for vehicles where cost constraints or vehicle weight limits are critical.

　　In addition, Nissan’s new advanced sound‑insulation material helps reduce vehicle weight, thereby improving fuel efficiency and lowering the car’s environmental impact. A quiet cabin enhances driving comfort and elevates the overall ride experience.
