Abstract (en)
[origin: EP0277064A1] 1. Ventilation device making possible acoustic insulation and installed in a pane or a wall (3), comprising two casings (1, 2) disposed on either side of said pane or wall (3), characterized in that it is constituted of : two identical casings (1, 2) of elongated form, comprising a ventilation aperture (4, 5) in one horizontal wall (6, 7) and which are disposed horizontally, symmetrically about a median horizontal axis, an intermediate support (9), on which each of said casings (1, 2) is fixed in removable manner, this intermediate support taking the place of said pane or wall (3), which has approximately the same mechanical characteristics as the latter and which comprises two circulation apertures (13, 14) disposed in a horizontal plane, and a sleeve (12) of washable laminated material, such as a foam, possessing acoustic insulating properties, surrounding said intermediate support (9) and forming, in combination with insulating materials situated in each of the casings, a duct (16) connecting said ventilation apertures (4, 5) and said circulation apertures (13, 14), so shaped that said duct (16) comprises only smooth walls without roughness.
