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.
