Beschreibung
Zusammenfassung:	The present invention relates to a dissipative vibratory wave barrier comprising a carrier having an inner surface and an outer surface, the carrier comprising on its outer surface a coating comprising a thermo-expandable material selected among those which, after expansion and at a temperature between -10 and +40°C, have a Young modulus E between 0,1 MPa and 500 MPa and a Shear modulus G between 0,1 MPa and 250 MPa.
