Nissan Has A New Solution for Soundproofing Its Vehicles

The Nissan Ariya Concept is being showcased at CES 2020 with a new technology, an acoustic meta-material. The latter is a lightweight sound insulation material.

  • Nissan has created an acoustic meta-material;
  • This new sound insulation material significantly reduces road noise;
  • CES visitors can experience it in the Nissan Ariya Concept at the Nissan booth.

Nissan, like most other players in the automotive industry, is at the CES (Consumer Electronics Show) in Las Vegas, this week. If Nissan showcasing one of their most recent prototypes – the Ariya Concept – does not surprise anyone, the presentation of a new solution to reduce noise inside future vehicles of the brand looks promising.

The meta-material that Nissan will show this week in Vegas is not only capable of reducing the effect of road noise (between 500 and 1200 hertz), but in addition, it allows designers to save on the total weight of the vehicle. Unlike the materials used today – generally made of a fairly heavy rubber -, the meta-material only weighs a quarter of the weight while providing similar or better soundproofing inside the cabin.

The honeycomb structure of this technological breakthrough is very simple, which means that the meta-material already demonstrates commercial potential. Nissan specifies, however, that to be commercially viable, this solution must be applied to mass production. The manufacturer also made it clear that the lower weight of the meta-material would allow certain models of the brand to receive more soundproofing than now.

What you must understand is that if Nissan succeeds in integrating this technology in its future models, the soundproofing should be like that of today, but with a potentially less significant weight, which should have a positive impact on energy efficiency.

The Japanese manufacturer began its research on meta-material around 2008.
