Video: Nissan Has Come Up With A Revolutionary Soundproofing With Holes
Nissan has unveiled a unique acoustic metamaterial in Las Vegas - a honeycomb noise-insulating coating that is both lighter and quieter than traditional Shumka. The novelty was tested on the conceptual crossover Ariya, shown back in the fall in Tokyo.
The new acoustic material has a honeycomb structure and is covered with an insulating plastic film. It resists vibrations in the air and limits noise levels over a wide spectrum (500–1200 Hz).
- According to the Japanese, the new coating provides a modern level of isolation from external noise (road or engine sounds), while weighing four times less than the materials used today.
- Switching to such a sound-absorbing material, according to Nissan, will at least not increase, but as a maximum will reduce production costs. Moreover, the new technology could be applied in areas of the vehicle where insulation is not currently used for cost or weight reasons.
