Abstract: Sealing strip (1) intended to be combined between a vehicle bodywork (2) and glazing (3), characterized in that it constitutes an acoustic damping means when subjected to the action of a vibrational field; it works in shear combined with local movements of the glazing in its plane, while the bodywork deforms in the direction of the local normal to the glazing.

Abstract: A method for optimizing sound and vibration comfort in a mobile passenger compartment, the method applied by a design team to carry out overall design of the passenger compartment and/or by at least one equipment supplier to carry out design of a portion of the passenger compartment. The method establishes target values to be achieved for well-identified comfort indices, defines requirements and input data relating to plural equipment suppliers to obtain a totality of information relating to the passenger compartment, estimates values of the comfort indices and compares them with the target values, and then modifies individually or in combination the input data to correlate them with the target values.

Abstract: Laminated glazing (2) comprising a viscoelastic plastic insert (3) comprising at least two damping films (30, 31) each having a loss factor tan ? greater than 0.6 and a shear modulus G? less than 2×107 Pa over two temperature ranges tA et tB respectively, characterized in that the film which has, at a frequency of 200 Hz, the highest loss factor tan ? over a given temperature range included within the temperature range tA or tB, has an equivalent shear modulus G?eq less than the equivalent shear modulus or moduli of the other film or films, with G eq ? = G ? ? e tot e where G? is the shear modulus of the material constituting the film, e is the thickness of the film and etot the total thickness of the insert.

Abstract: A sealing strip configured to be combined between a vehicle bodywork and glazing, and including an acoustic damping mechanism when subjected to action of a vibrational field. The sealing strip works in shear combined with local movements of the glazing in its plane, while the bodywork deforms in the direction of the local normal to the glazing.
