The invention relates to an acoustic insulating glazing unit. This glazing unit comprises two glass sheets (12, 14) joined together around their periphery by means of an assembly (16) forming a seal (163) and an insert frame (161) which defines, with the two glass sheets, a flat cavity filled with a gas, and a waveguide fastened between the glass sheets, internal to the insert frame. The waveguide consists of at least one straight tubular section (20, 22, 24, 26) placed on the periphery of the gas-filled cavity along one side of the glazing unit, this section being provided with a transverse partition (28) which closes the latter in its length direction, the said partition being placed at a length position along the section which depends on the acoustic mode of the cavity that it is desired to disorganize, this partition defining, on either side of it, two chambers (30, 31) which communicate with the cavity through the ends of the sections.

1. An acoustic insulating glazing unit comprising: two glass sheets joined together around their periphery by means of an assembly forming a seal and an insert frame which defines, with the two glass sheets, a flat cavity filled with a gas; and a waveguide fastened between the glass sheets, internal to the insert frame, wherein said waveguide comprises at least one straight tubular section placed on the periphery of the gas-filled cavity along one side of the glazing unit, said section provided with a transverse partition which closes said section in a length direction, said partition placed at a length position along said section which depends on the acoustic mode of the cavity that it is desired to disorganize, said partition defining, on either side, two chambers which communicate with the cavity through an end of said section. 2. The glazing unit according to claim 1, wherein said glazing unit comprises a plurality of waveguide sections placed along a length of one or more sides of the cavity. 3. The glazing unit according to claim 1, wherein the partition of the section is placed approximately halfway along a length of the section. 4. The glazing unit according to claim 1, wherein the partition is placed from one third to one quarter of the way along a length of the section. 5. The glazing unit according to claim 1, wherein the partition is selected from the group consisting of partition connector, a heat-welded constriction in a thermoplastic section, a buffer of acoustically absorbent material slid into the section and a partition slid into the section. 6. The glazing unit according to claim 1, wherein the insert frame of the insulating glazing unit and the at least one waveguide section, is separate and juxtaposed. 7. The glazing unit according to claim 1, wherein the at least one waveguide section acts at the same time as the insert frame. 8. The glazing unit according to claim 1, wherein the at least one waveguide section is provided, along a face in contact with at least one glass sheet, with a longitudinal groove forming a safety reservoir for retaining, in the case of creep, a material which serves to adhesively bond the glass sheets to the insert frame. 9. The glazing unit according to claim 1, wherein a plurality of straight tubular sections are joined together to form a continuous frame having the same shape as the glazing unit, said continuous frame having a plurality of apertures cut into inner corners of said frame in order to make the chambers of the sections communicate with the cavity (18). 10. The glazing unit according to claim 1, wherein a plurality of sections are joined together by a plurality of tubular corner pieces a plurality of the legs of which fit into the ends of the sections, said corner pieces having an orifice at an internal edge in order to make an internal space of the sections communicate with the cavity of the glazing unit. 11. The glazing unit according to claim 9, wherein a plurality of sections are separate and the chambers communicate with the cavity (18) through the open ends of the sections. 12. The glazing unit according to claim 1, wherein the waveguide contains an acoustic absorbent. 13. The glazing unit according to claim 1, comprising four waveguide sections.
