Recently, Nissan's noise reduction technology, the lightweight Acoustic meta-material, won the 2020 Best of What's New invention in the automotive field from the American "Popular Science" magazine. "Grand Prize. This technology helps to improve the quietness and fuel economy of the vehicle.
Founded in 1872, "Popular Science (New Era of Technology)" is one of the oldest and most trusted magazines in the United States, focusing on disruptive innovations and discoveries. The "Best of What’s New" awarded by the magazine aims to recognize products and technologies that have made major breakthroughs in various fields.
Nissan's lightweight super sound insulation material is a new lightweight sound insulation material. Its structure is very simple. It is composed of crystal structure and plastic film, which can effectively control air vibration and reduce the transmission of broadband noise (500-1200Hz) generated when the vehicle is running and the engine is running. At present, most of the sound insulation materials in this frequency band are made of heavy rubber, and Nissan's super sound insulation materials have been lightweighted, so that the vehicle can reduce the weight by 75% compared with traditional sound insulation materials without changing the sound insulation effect. .
The lightweight super sound insulation material is the crystallization of the wisdom of Nissan's engineers. It reduces the weight of the vehicle body and increases the mileage, while also providing a comfortable and quiet driving experience for the driver and passengers.
Mr. Susumu Miura, Nissan's senior material engineer and head of the lightweight super sound insulation material project, said: “We plan to apply lightweight super sound insulation materials to luxury vehicles, electric vehicles and vehicles that cannot use heavy-duty sound insulation materials. Through the development and use of lightweight super sound insulation materials, we will strive to provide consumers with a more comfortable and enjoyable driving experience."
Nissan's lightweight super sound insulation material is currently still in the commercial development stage and is one of the measures to improve the driving experience through the "Nissan Intelligent Mobility" technology.
