- GLAZING HAVING IMPROVED VIBRO-ACOUSTIC DAMPING BEHAVIOUR METHOD OF MANUFACTURING SUCH GLAZING AND METHOD OF ACOUSTIC PROTECTION IN A VEHICLE PASSENGER COMPARTMENT

摘要

An improvement with at least one vibratory acoustic damping strip (2) comprising at least one glass sheet (10) and at least one component (20) attached to at least one side of the glass sheet and consisting of a damping material with a loss factor greater than 0.2 Wherein the strip 2 is not bonded to any other device on the opposite side of the glass sheet and the component consisting of the damping material is within +/- 30% of the critical frequency of the glazing unit, And a Young's modulus at 20 DEG C of more than 800 MPa.
