Article source: Autohome/Yuchen said car? Recently, Nissan's noise reduction technology-lightweight Acoustic meta-material was awarded the 2020 Car of the Year by the American "Popular Science" magazine "Best of What's New" award in the field
.
This technology helps to improve the quietness and fuel economy of the vehicle
.
? Founded in 1872, "Popular Science" 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 a crystal structure and a 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 light-weighted, which enables vehicles to 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 car body and increases the mileage, while also providing a comfortable and quiet driving experience for the drivers and passengers
.
? Mr.
Susumu Miura, a senior material engineer at Nissan and the leader 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 pleasant driving experience
.
? Nissan's lightweight super sound insulation material is still in the commercial development stage, and it is one of the measures to improve the driving experience through the "Nissan Intelligent Mobility" technology
