like, and the primary object ofthe invention' 5 is to provide a wall structure for the treatment of acoustics. -4
'A further object is to provide a wall st iucturewhich will be highly absorbent to vsound wavesor preventing undesirable reverbera- 19 tion, and possessing characteristics aording- L .-where 1n similar reference characters desiga desired 'amount of resonantv quality. to the wall. 'j t y A further object` is to provide an acoustic wall structure which may be'v economically l5 manufactured, is nonina'mmable, and which v may either be applied asa coating directly to the wall or moulded into blocks or slabs of I' suitable shape and size for application to the wan.1 .x 1-".
A further object of the invention resides in the provision of an acousticwall structure' composed of a .plastic mater1al of suchznature. /as to provide intercommun1cat1ng voids or interstices opening at the face or exposed surface of the wall and *having embedded in isolated relation therein, elastic bodies providing spaced apart vibratory or resonant sections having irregular channels therethru between the elastic bodies and wall surface.-
A further object is to provide a porous wall structure having porousvibratory s'ec 'tions for 'adording some resonant quality to the wall, with damping means'l for the vibra,- tory sections. v
`@therobjects and advantages of the invention will be apparent from the' following detailed descriptiom'taken in connection with the accompanying drawing forming a part of this speciication and in which drawing:
i Figure l is a. plan view of a block or slab `formed in accordance .with this invention.
Figure 2 is an enlarged fragmentary sec.-
tional view oi a wall embodying the features os? this invention and lshowing the porous formation of the. acoustical material providing the open. voids or interstices. l j
` Figures 3 and 4 are sectional views on the respective lines in Figure 1 end .showing theA 'position of theelastic damping padwithin lo the body material of the block orslab, with- Y 'out showing in detail theopen voids oninter- .stices between the granules ofthe body material as disclosed clearlyrin Figure 2.
Referring tothedrawing in detail 'and so nate correspondingparts thruout the several views, the letter A designates an acoustic wall block or slab constructedin accordance with this inventionand B a basefwall struc- @A I ture-which in the exampleshown is of solid' masonry construction; such types of walls being non-absorbent 'and practically impervious to sound waves.
, I he wall slab A may be moulded.. inanydesirable shape and size found most suitable and is formed of .the plastic body. material '5 in which lis embedded an elastic body 6 havin its margins spaced wholl inwardl ofthegsurfaces ofthe slab.. y y 70 While the'l compositionV ofthe absorbent body material 5 may bevaried toa certain extent,l a structure possessing the Adesired i A characteristics'has been obtained inthe ollowing manner s-Granular 'material such as' 15 lcrushed brick, oyster shell, coke or slag-oi.:`
a size toI pass thru a number eight mesh y screen, lifty per cent by volume; Vplaster of .Paris or any "gypsum plaster, twenty-hva per V `cent by volume; and water twenty-five per 89 'cent-'by volume. A smallquantityoi some.
retarder Vsuch `as carpenters l[glue may be added to this mixture,v the, quantity depending upon conditions at the time of mixing. A body material'so formed may either be 85 applied directly to a base wall structure or Amoulded into suitablyshaped blocks or slabs vhaving an approximate thickncssof one inch and then applied to the wall as by a suitable binding material as shown at 8 inligure 2.
The specific proportions may be varied slightly and in some instances it may be found desirable to use` a mixture of two or more of the granular materials. y
Referring to Figure 2, a body material 5 so formed Will provi-de irregular inter-'communicating voids or interstices l0 about the o'ranules o-the ybody material so that the -block or slab A is rendered very porous and highly absorbent to sound Waves. These voids or interstices 10' extend to and open at the face or exposed surface of the block and the formation of the voids is due tothe small quantity of Water used in the mixing i and'also the small quantity of binder used Embedded in the porous body material- 5 is the elastic body 6 which may be in the form of a thin sponge rubber pad spaced below the face side or exposed surface of the Wall block and providing a vibratory or resonant section 2O having its margins spaced inward from the marginal edges of the block as shown .by dotted lines'in Figure l. As will be seen in Figure 2, the voids 10 extend lthru theJ vibratorysection 2O from the pad 6 to the surface of the block so that a porous section of a vibratory character is-formed over the yieldable pad for affording some resonant quality to the Wall. This cellular pad 6 aside from adding to the sound absorbing quality of the block, acts as a cushioning element for damping the vibrations of the porous vibratory section 20 whereby an excessive amount of sound reflection is eliminated.
When the blocks or tiles are applied as a facing to a base Wall construction, a Wall structure having a high degree of sound absorption `Will be formed, provided with isolated damped vibratory sections affording some resonance quality to the Wall. When the body material 5 is applied directly to the base Wall construction,v the pads 6 are embedded in the material at about one quarter of an inch below the surface thereof and in spaced relation to one another so as tov Aprovide isolated damped vibratory sectionsl over the entire Wallvsurface.
In place 'of the sponge rubber pads for damping vibrations of the vibratory sections 20, I may use sheets of corrugated material or any other sheet Alike material of a porous yieldable character capable of providing a cushioning eiect upon the vibratory sections. While the elastic pads 6 have been shown of rectangular shape it is to be understood that these pads may be of various other sha es. l
rom the' foregoing it will be apparent that an improved construction for Wall and ceiling structures has' beenprovided for the treatment of acoustics, possessing marked qualities of sound absorption and embodying damped vibratory sections for affording some resonant/qualities to the Wall.
Changes in detail may be made to the form of invention herein shown and described -Without departing from the spirit-of the invention or the scope of the following claims.
I claim:
l. A Wall or ceiling structure embodying a coat of porous material formed With isolated vibratory sections on its surface, and damping means for the vibratory sections.
