Definitions

  • This invention relates to a soundproof structure for facing the ceilings and walls of generic interiors, in particular so-called open-space working interiors.
  • soundproof structures are those which afford the highest number of sound "traps".
  • structures have been proposed which comprise composite panels defining plural cells, accessible from the working interior space, into which sound becomes trapped almost completely.
  • Other soundproof structures comprise deeply “wrought” surfaces, and specifically foam material boards, for example, which have their surfaces facing the interior space formed with plural pyramid- or cusp-like projections arranged in rows and arrays and having varying depth dimensions.
  • this invention provides a soundproof structures for working interior facing, and particularly for so-called open-space interiors, characterized in that its surface is lined at least in part with a layer of a catadioptric reflective material.
  • the layer of catadioptric reflective material forms a light source on a light beam impinging on it. Furthermore, by virtue of the recognized properties of said material, the lighting effectiveness of such a light source is quite unaffected by the more or less wrought character of the soundproof structure employed.
  • a soundproof structure has been used to face the ceiling of an interior space 1, e.g. a so-called open-space working interior.
  • the soundproof structure comprises a plurality of substantially box-like cells which are orderly arranged in parallel rows and arrays and are each provided, at their wall 3 confronting the working interior 1, with a circular opening 4.
  • the inner wall of each cell 3 lying remotely from its respective circular opening 4 is lined with a layer 5 of a catadioptric reflective material (e.g., a catadioptric film, catadioptric paint, etc.).
  • a catadioptric reflective material e.g., a catadioptric film, catadioptric paint, etc.
  • the cells 2 are known to form highly effective traps for the acoustic waves which enter them through the openings 4.
  • each cell 2 is also penetrated, through the openings 4, by the light radiation from the sources 8 and 9, but this radiation is not trapped within the cells because, after impinging on the catadioptric surfaces 5, it is reflected thereby out of the cells.
  • the catadioptric material layer 5 of each cell 2 substantially forms a light source which contributes toward lighting the working interior 1 along with the rest of such like sources.
  • a single large size cell 10 accessible from the outside through a plurality of openings 11, accommodates a layer 12 of a soundproofing material whose wall facing the working interior space has been "wrought" with a plurality of projections and recesses which, when viewed in cross-section, impart to it a substantially fretted pattern.
  • This wall is completely covered by a layer 13 of a catadioptric material.
  • a panel 21 of a foam material is formed with a plurality of ribs 22 delimiting, in cooperation with a plurality of flat staves 23, a corresponding plurality of cells 25.
  • the staves 23 are set apart to define an access passage to the cells 25.
  • the walls of the cells 25 remote from said passages, are provided with a layer 26 of a catadioptric material.
  • the soundproof structure embodiment of Figure 4 comprises a panel 15 of a foam material whose wall facing the working interior space is formed with a plurality of pyramidal cusp projections 14 orderly laid in parallel rows and arrays.
  • the outer walls of each cusp 14 have respective linings 16 of a catadioptric material.
  • the soundproof structures shown in Figures 5 to 7 are of the so-called staved type (indicated at 17, 18 and 20, respectively, in said Figures), which is highly effective to trap sound. More specifically, the soundproof structures of Figures 5 and 6 are provided with a plurality of sound breaking reeds 19. In accordance with this invention, the staves and sound breaking reeds are both lined with respective layers of a catadioptric material.
