description The design of innovative metamaterials with robust and reliable performances is attracting increasing interest in shipbuilding, due to the potential and versatility of these materials. In particular, soundproofing is becoming an even more important characteristic, to ensure the comfort levels required by the standards on board ships. Thus, shipyards are constantly looking for innovative solutions to improve the insulation between environments, while respecting the safety regulations with which the materials on board must comply. In this study, an innovative solution called the Metasolution is designed and characterized, considering both the transmission loss (TL) and the fire resistance. The Metasolution is proven to be a valid substitute for the traditional honeycomb panels used on board for soundproofing. The TL of the innovative solution is increased, and the thickness is decreased, while maintaining the cost and the weight in line with the traditional solution. Moreover, the regulations regarding fire safety on board are satisfied.
