Definitions

  • WILBUR S. TRADER OF ST. LOUIS, MISSOURI, ASSIGNOR TO DAHLBERG & COMPANY, OF CHICAGO, ILLINOIS.
  • This invention relates to sound absorbing boards or material, and has for its object to provide an article of manufacture that will be simple in construction and for the same absorbing capacity will be less costly to make than those heretofore proposed.
  • the invention consists in the novel 'parts and combinations of' parts constituting my improved sound absorbing board7 all as will be more fully hereinafter disclosed and particularl)v pointed out in the. claims.
  • Figure .l is a diagrammatic perspective viewrof a room or enclosure lined with my improved sound absorbing board;
  • Figure 2 is a diagrammatic cross sectional view of a Celotex or Insulite board showing perforations extending entirely through the board;
  • Figure 3 is a modified view .ofaperforated board showing an additional member for covering the perforations on one slde of' the said board;
  • Figure 4 is a modified view'V similar. to Fig. 3, wherein the perforations are not carried entirely through the board;
  • Figure 5 is a plan View of a Celotex or Insulite board showing one pattern in which the perforations may be arranged;
  • Figure 6 shows a further modified orm of perforations
  • Figure 7 shows a still further modified form of Celotex or Insulite board having channels instead of perforations to enhance the sound absorbing qualities
  • Figure 8 illustrates a perforated Celotcx or Insulite board spaced from a supporting wall:
  • Figure 9 is a plan view of a board partially broken awa-y and provided 'with perforations of different diameters.
  • Figure l0 is a sectional view taken on the line 10-10 of Fig. 9.
  • y ln the somewhat modified form of the invention shown in Fig. 3. the same construction is provided except the thin sheet or diaphragm 7 is placed on one surface of the fibrous board' l. in order to hide the. ends of the perforations 2.
  • This sheet or diaphragm 1 7 may be made of any desirable porous material, such for example as burlap or other fabric that can be readily colored or made to harmonize with the surroundings.
  • the sheet'7 may be made of Celotex or Insulite itself.
  • the erforations 2 are not carried entirely through the Celotex board 1, but are stopped short of one surface thereof so as to form the integral Celotex or Insulite portions 8. as illustrated.
  • the Celotex or Insulite surface 8 can be readily exposed in the room or enclosure and finished up as has been lll) heretofore done in the case. of unperforated Celotex or lnsulite, but the sound absorbing qualities0 of the board are somewhat im paired.
  • the perforations 11 are made tapered or coneshaped as .shown so that the sound waves are gradually converged to a point as they penetrate the main body portion of the fibrous board and thus are'more and-more forced into the interior of the board and are thus eectnally lost among the interstices of said board. 1
  • the board 1 is provided with the elongated grooves 12 which may be ofany desired contour or cross section and the sound wavesl readily enter the same and penetrate the interstices of the adjacent orus masses in the same manner as was dlsclosed in connection with Fig. 2.
  • t should be remarked that in all cases, perforations or openings in the CeloteX or nsulite boards are never molded. Should they be molded, they would inevitably form the above-mentioned objectionable skin or film which would reflect the sound rather than aid in absorbin the same. In making the perforations o this invention they are always cut, gouged, drilled or sawed out so as to tear loose the chips or shavings from the adjacent fibers, thus leaving a rough and fibrous surface to be readily penetrated by the sound waves.
  • the perforations are of two diameters.
  • TheY larger perforations 13 with which the board 16 is provided are preferably concentrically disposed with .relation to the smaller perforations 14""With which the board 17 is provided, so that a sound wave entering the larger perforations would strike against the bottom walls 15 formed by the surface of the board 17, and they would naturally immediately be more or less compressed and forced into the smaller perforations 14, where they would enter the interstices of the individual masses 18 of the board 17.
  • rl ⁇ he board 1 is conveniently spaced from the support or wall 22 by any suitable means such as the struts 23, and these said struts are conveniently provided with perforations 24 so that hot air or other medium having a density diiferent from that of the room may be forced through such space 20 and thus further absorb the sound.
  • any suitable means such as the struts 23, and these said struts are conveniently provided with perforations 24 so that hot air or other medium having a density diiferent from that of the room may be forced through such space 20 and thus further absorb the sound.
  • a sound absorbing construction involving a porous fibrous board 1 which is preferably of predetermined dimensions so that it constitutes a sound absorbing unit. It will further be clear that although this board or unit 1 has a highly porous interior, yet its surface, although porous, is not as porous as is its interior when cut through, or perforated by a gouging, punching, sawing or tearing action, and that therefore the raw edges of such perforations'or openings serve to facilitate the entrance of sound waves into the interstices of the porous interior of said boards.
  • a board having a given number and disposition of o enings per unit of area will have a certain eterminable sound absorbing eliiiency, and duplicate boards can be readily Cil produced, so thatl the sound absorbing capacity of a given number of square feet of perforated surface, may be readily determined in advance. This enables the architect to prepare a sufficient number of units of perforated surface for any given enclosure and to know with certainty their sound absorbing effect before they are put in place.
  • Vhat is claimed is 1.
  • a sound absorbing construction comprising a building board of fibrous material having a porous interior with sound absorbing properties, and' provided with independent artilicial openings extending inwardly from a surface of said material, where y sound waves may enter said openings and be ⁇ absorbed by said porous interior.
  • a sound absorbing construction comprising a building board composed of Vegetable fibres and having a porous interior possessing sound absorbing properties, and provided with a predetermined number of independent artificial openings of larger dimensions than are the ores of the material and extending inwar ly from a surface thereof, whereby sound waves may enter said openings and be absorbed by said interior.
  • the herein described sound absorbing unit composed of a porous bagasse fibre board of predetermined dimensions and provided with artificial openings extending into the interior thereof, whereby sound waves may enter said openings and be absorbed.
  • the herein described sound absorbing unit composed of a board made from a mass of compressed bagasse fibres and having a porous interior, said board provided with numerous openings communicating with said interior and adapted to conduct sound waves to the pores thereof.
  • the herein described sound absorbing member consisting of a building board composed of compressed bagasse fibres providing a porous interior and having a sufiicient number of openings communicating with said interior to substantiallyincrease its sound absorbing qualities.
  • a fibrous porous building board of sound absorbing material provided with openings communicating with its interior; a wall; and means to space said layer from said wall.
  • a fibrous, porous building board of sound absorbing material provided with perforations extending entirely through said layer; a wall; and means to support said layer away from said wall and provide a space into which said perforations open.
  • a sound absorbing unit of known value consisting .of a fibrous porous building board provided with a predetermined number of perforations extending inwardly from one of its surfaces and having a known sound absorbing capacity.
