ACOUSTIC INSULATING GLASS WITH PARTITIONED WAVEGUIDE

摘要

The invention relates to an acoustic insulating glazing, comprising two sheets of glass (12, 14) assembled at their periphery by means of an assembly (16) forming a seal (163) and an intermediate frame (161) which defines with the two glass sheets a flat cavity filled with a gas, and a waveguide fixed between the glass sheets, inside the intermediate frame. The waveguide consists of at least one straight tubular profile (20, 22, 24, 26) disposed at the periphery of the gas-filled cavity, along one side of the glazing, this profile being provided with a transverse partition (28), which closes it in the direction of its length, said partition being arranged at a point of length of the profile which is a function of the acoustic mode of the cavity which it is desired to disorganize, this partition defining on the one hand and on the other, two chambers (30, 31) which communicate through the ends of the profiles with the cavity.
