The invention relates to sound insulation glazing. Said glazing comprises two sheets of glass (12, 14) which are assembled on the periphery thereof by means of a unit (16) forming a sealed joint (163) and an interlayer frame (161) which defines a flat gas-filled cavity in conjunction with the two sheets of glass, and a wave guide which is fixed in between the sheets of glass on the inside of the interlayer frame. The wave guide is made of at least one rectilinear tubular profiled section (20, 22, 24, 26) which is disposed on the periphery of the gas-filled cavity along the side of the glazing, whereby said profiled section is provided with a forming transversal wall (28) in the direction of the length thereof, and said wall is disposed in a long part of the profile section according to the acoustic type of cavity which is to be disorganized, whereby said wall defines two chambers (30,31) on both sides thereof and said chambers communicate with the cavity via the ends of the profiled sections.
