Definitions

  • This invention relates to a material of soundabsorbing qualities intended to be used for acoustical purposes and is a continuation-in-part of certain subject-matter disclosed in my earlier application Serial No. 62,739, filed February 7, 1936.
  • my. invention consists of a layer of compressible material carrying a covering sheet which has an irregular or non-plane surface and which is adapted to undergo certain localizedmovements independent of the movement of the covering sheet as a whole resulting from compression of the-underlying material.
  • sounds in the lower frequency ranges tend to cause the covering sheet to move bodily and compress the underlying material.
  • the covering sheet is approximately fiat and fairly stiff and hard, the sounds of higher frequency may not be satisfactorily absorbed. Since it obviously is desirable to finish a wall with a surface of good appearance, some type of covering sheet is desirable. Accordingly, I use a covering sheet which has portions lying in the plane of the face of the main sheet and portions raised relative thereto.
  • FIG. 1 is a perspective view of one form of device embodying my invention with a portion of the covering sheet broken away;
  • Fig. 2 is a perspective view of a modified type of structure
  • the main sheet 22 is a flat sheet of hair felt, to one face of which is attached a 5 molded member 24 having raised portions 26 between which are sunken ridges 28.
  • the sheet 24 is attached to the sheet-22 by the ribs 28 and preferably the two are connected together adhesively.
  • the sheet 24 can be formed from soft sheeted material such as asbestos or paper stock by rolling and pressing or it may be molded directly in shape from pulp or any type of mixed paper stock. Any of these materials are intended to be embraced within the term paper like material.
  • a structure for sound deadening or sound absorption comprising a facing member carrying a covering sheet consisting essentially of sheeted, paper-like material and having portions in contact with the facing member and portions raised relative thereto, the area of the raised portions being greater than the area of the portions in contact with the facing member, and a spacing member adapted to hold such facing member in spaced and cushioned relation to a wall member consisting essentially of soft, compressible'material.
  • a structure adapted for use for acoustical purposes comprising an underlying layer of com- 40 pressible material and a covering sheet consisting essentially of sheeted, paper-like material in part afiixed to the underlying material and in part raised relative thereto, the area of the raised portions of the covering sheet being greater than the area of the portions affixed to the underlying material.
  • a structure adapted for use for acoustical purposes comprising an underlying layer of compressible material and a covering sheet consisting essentially of sheeted, paper-like material which is attached to the underlying material through portions lying in a common plane and having portions raised relative thereto, the area of the raised portions being greater than the area of the portions lying in a common plane with the underlying material.
  • a structure for sound absorption comprising an underlying layer of compressible material and .a covering sheet consisting essentially of sheeted,
