    Abstract: PROBLEM TO BE SOLVED: To obtain a suitable sound-proof effect to noise by keeping glass from having a radiation mode connected to a cavity mode of a car compartment when the glass is excited by a sound field. SOLUTION: A fixed side window glass 2 adjacent to a peripheral packing 3 is kept from having at least one or plural radiation modes connected to one or plural cavity modes when the glass 2 is excited by a sound field. Though a method therefor is not limited, a distortion spot which is a local deformed part, or a grown part is formed in the edge of the glass 2, and the movement of the glass 2 is locally decreased in that part to achieve the object. Thus, when two radiation zones of opposite phases are generated and the radiation zone 5 is moved in a designated direction, the radiation zone 6 is moved in the opposite direction to produce a cancel or compensation effect. Accordingly, applied radiation is reduced and transmission of noise is decreased so as to improve a damping effect in the interior of a cabin.

    Abstract: PROBLEM TO BE SOLVED: To obtain a multiple glass aggregate excellent in sound proofing property and heat insulating property, capable of maintaining common rebate depth, by hermetically bonding glass plates laminated through a plastic sheet to a single glass plate through a void packed with a gas. SOLUTION: At least two glass plates 5 and 6 having 1-3.2mm thickness are laminated through a plastic film 6 having >=3.8mm thickness formed from a resin having a resonance frequency fc in 35% difference between a strip which comprises a glass plate obtained by laminating two glass plates having 4mm thickness with a resin of 2mm and has 9cm length and 3cm width and a first mode of a glass plate of a monolith having the same length, the same width and 4mm thickness to give a laminated glass 2. The laminated glass 2 is hermetically bonded to a glass plate 3 having 2.5-8.2mm thickness through a void 4 having 6-20mm thickness charged with a gas.

    Abstract: PROBLEM TO BE SOLVED: To obtain such a laminar glazing assembly for an automobile that has an intermediate film having a good dampening effect against propagation of noise through the automobile body by laminating a glass plate and a specified intermediate film to constitute the laminar glazing assembly. SOLUTION: This laminar glazing assembly consists of at least one glass plate and an intermediate layer film having >0.6 loss angle tan δ at 10 to 60 deg.C in 50 to 10000Hz frequency range and N/cm modulus of elasticity in shear G'. The dynamic characteristics of this material are measured by using a viscosity analyzer such as a Metravid viscosity analyzer. The laminar glazing assembly consists of, for example, two silicate glass plates 1, 2, two polyvinylbutylal layers 3, 4, two thin PFT films 5, 6 and a viscoelastic acrylpolymer film 7 inserted between these films.
