One of the key points for the success in the construction of cruise ships is the enhancement of high standards for passengers comfort on board, especially in the living and resting areas. For this reason, one of the fields on which research in this sector is focused on is the reduction of airborne and structure-borne noise transmitted inside the cabins. At present, the floating floor arrangement is commonly used on board in order to reduce the structural noise transmitted through floors. This special floor decouples the inner floor of the cabin from the load-carrying structure of the deck. In the present study, the performances of two floating floors with innovative de-coupling materials have been analyzed. The floors were tested in the condition of unloaded floor and loaded floor.

Abstract
One of the key points for the success in the construction of cruise ships is the enhancement of high standards for passengers comfort on board, especially in the living and resting areas. For this reason, one of the fields on which research in this sector is focused on is the reduction of airborne and structure-borne noise transmitted inside the cabins. At present, the floating floor arrangement is commonly used on board in order to reduce the structural noise transmitted through floors. This special floor decouples the inner floor of the cabin from the load-carrying structure of the deck. In the present study, the performances of two floating floors with innovative de-coupling materials have been analyzed. The floors were tested in the condition of unloaded floor and loaded floor. Modal analysis techniques have been applied to understand the overall results obtained in terms of general indicators.
