GLAZING WITH IMPROVED VIBRO-ACOUSTIC DAMPING PROPERTIES, METHOD FOR MAKING SUCH GLAZING AND METHOD FOR ACOUSTIC PROTECTION IN A VEHICLE PASSENGER COMPARTMENT

摘要

The invention relates to a glazing (1) with improved vibro-acoustic damping properties, that comprises at least one glass sheet (10) and at least one vibro-acoustic damping profile (2) connected by at least one face thereof to the glass sheet and including at least one member of a damping material (20) having a loss factor at least equal to 0.4 and a Young modulus lower than 200 MPa at 20°C for frequencies lower than 5000 Hz. The profile (2) also includes a weighing member (3) having a lineic mass higher than 0.05 kg/m and connected to the member made of a damping material (20), the member made of a damping material being provided between the glass sheet and the weighing member, and no other device except the glazing is associated with the profile.
