<p>The system has a cladding (V) fixed to an absorbing layer (D), which has an inner dissipation factor of at least 0.1, preferably at least 0.2. A noise insulation layer (S) on the other side of the cladding or the absorbing layer from the room seals the system at the floor (U), wall or ceiling and has a dynamic stiffness that is not more than 20 MN/m<3>, but preferably not more than 10 MN/m<3>.</p> |
