Abstract: The window includes two parallel glass panes separated by an air gap and assembled within a window frame. The frame is filled with a drying substance and glued with butyl. A waveguide is built at the window edge which communicates, through eight holes, with the air gap between the panes.

Abstract: An acoustic window intended for land transport vehicles is proposed. Its index of acoustic attenuation differs by no more than 5dB from an index increasing by 3dB per octave from 800 to 2000 Hz, and by 1 dB per octave above this range. The examples are doubled-glazed windows or laminated windows in which the intermediate layer has a high attenuation. It is effective with respect to aerodynamic noise.

Abstract: The acoustic insulation unit for an air hole in a window frame consists of a cover for the hole which encloses an absorbent element. The unit is made in the form of a casing, e.g. of aluminium or a synthetic material, containing an absorbent element which is of a larger area than the holes in the window frame. In between the absorbent element and the frame there is a gap which forms a duct joining all the air holes along one side of the frame. The casing can be aligned symmetrically with the hole or offset to one side. The frame can have an insulation unit on one or both sides.

Abstract: The invention relates to a multiple window glass comprising a first laminated glass plate and a second simple or laminated glass plate, parallel to the first and separated from it by a gas layer, the two plates being held together in a gastight manner. The resin of the laminated glass of the first plate (1) is chosen so that a bar 9 cm long and 3 cm wide, consisting of a laminated glass comprising two glass sheets 4 mm thick joined by a 2 mm layer of this resin, has a critical frequency that differs at most 35% from that of a glass bar having the same length, same width and 4 mm thickness.

Abstract: The invention relates to a viscoelastic plastic interlayer intended to be incorporated between two glass sheets to form a laminated glazing with vibro-acoustic damping properties, the interlayer comprising at least one layer (3) made of viscoelastic plastic with vibro-acoustic damping properties, the interlayer being such that the resonant frequency f2 of the second resonance mode of a laminated glazing bar with a surface area of 25 mm x 300 mm composed of two glass sheets each 2.1 mm thick, between which is incorporated the interlayer, determined by measuring the mechanical impedance (MIM) at 20?C according to standard ISO 16940, is between 760 Hz and 1000 Hz and the loss factor n2 of the second resonance mode of the same bar, determined by MIM under the same conditions, is greater than or equal to 0.25. The invention allows a reduction in the thickness of glass sheets without degradation of the vibro-acoustic damping properties. Fig. 1.

Abstract: L'invention concerne un procédé de sélection d'un intercalaire plastique viscoélastique comprenant deux couches externes et une couche centrale et destiné à être incorporé entre deux feuilles de verre d'un vitrage, le procédé comprenant les étapes suivantes : - on fournit des premier et deuxième éléments destinés à constituer respectivement la couche centrale et les couches externes, - on mesure le module de cisaillement G' des premier et deuxième éléments, - on sélectionne le matériau du deuxième élément uniquement si G' > 3.107 Pa à 20°C et entre 100 Hz et 240 Hz, - on fixe l'épaisseur h du premier élément telle que h est comprise entre 0,31 mm et 1,20 mm et que g=G7h est compris entre 5,58.108 Pa/m et 2,37.109 Pa/m à 20°C et entre 100 Hz et 240 Hz. L'invention permet d'optimiser l'amortissement des deuxième et troisième fréquences propres d'un pare-brise de véhicule sans alourdir le pare-brise.
