INVESTIGATION ON NEW MATERIALS FOR NOISE AND VIBRATION LEVELS ATTENUATION
On site measure ment campaign and laboratory tests
The noise and vibration levels measurements on board of different ships are carried out to check the condition of the structure and evaluate the efficiency of vibro-acoustic treatments. These activities allow the company to create a large data base of vibration and noise levels data.
The laboratory tests allow the verification of the quality of materials proposed as an improvement. All the materials are tested on through the implementation of a mock-up in order to verify the materials properties in terms of vibro-acoustic damping.
