ACOUSTIC BLOCK OR TILE Filed Nov. '7, 1951 LVVENCIOR. flan/as (Kw Kama ATTORNEYS Patented Nov. 3, 1953 UNITED STATES PATENT OFFICE 1 Claim.
This invention relates to acoustic wall and ceiling construction, and in particular a block of acoustic material for use in servicing walls and ceilings of buildings where sound is objectionable.
The purpose of this invention is to embody ferring or ferring strips in a facing block for wall construction whereby an eflicient acoustic block is provided.
The principle of construction of acoustic blocks or tile used in building walls and the like, is that any broken surface will offer less reflection to a projected sound wave to adjoining walls, ceilings or other surfaces. It is a well known fact in acoustic treatment that to provide ferring strips for wall surfaces covered with acoustic treatment, regardless of the material used the effectiveness of this material is greatly increased.
With this thought in mind this invention contemplates means for incorporating an area within the acoustic block providing an air space between outer and inner sections of the block wherein the sections are spaced with strips and in which spaced openings through the outer sec tion are angularly positioned.
The object of this invention is, therefore, to provide an improved acoustic block which, in addition to the broken surface obtained by openings through the block includes an open area or pocket which forms a sound trap for the projected wave within the body of the block.
Another object of the invention is to provide an improved acoustic block that may be used in wall and ceiling construction and that may be substituted for conventional acoustic blocks with indentations in the surface.
A further object of the invention is to provide an acoustic block or tile which includes the effectiveness of furring strips which is of a simple and economical construction.
With these and other objects and advantages in view the invention embodies an acoustic block having a continuous inner panel or base with an outer panel spaced from the inner panel by strips and with spaced openings extended through and angularly positioned in the said outer panel.
Other features and advantages of the invention will appear from the following description taken in connection with the drawings wherein:
Figure 1 is a perspective view illustrating the improved acoustic block of this invention.
Figure 2 is a cross section through the block taken on line 2-2 of Figure 1.
Figure 3 is a horizontally disposed section taken on line 33 of Figure 1 looking upwardly.
Referring now to the drawings wherein like reference characters denote corresponding parts the improved acoustic block or tile of this invention is formed with an inner or base panel l0, an outer panel ll, spacing strips l2 and I3, which space the outer panel from the inner panel, and spaced openings through the outer panel, which in the design shown, include a row of perpendicularly disposed openings M with angularly disposed opening 15 on one side and similarly positioned opening I6 on the opposite side, the openings [5 and I6 being inclined toward the center and extending from the outer surface to the inner surface of the outer panel ll.
With the parts formed in this manner the acoustic block, which may also be formed of tile, is provided with an open area or sound trap I! wherein projected sound waves passing through the openings [5 and I6 strike the surface ill of the base l0 and rebound against the inner surface l9 of the outer panel I I. By this means the sound waves are not reflected back through the openings and as the sound waves are trapped in the area I! an acoustic block of the highest efficiency is provided.
It will be understood that the block may be formed of any suitable material, preferably of the conventional acoustic materials and it will also be understood that changes may be made in the design and arrangement of the parts without departing from the spirit of the invention.
What is claimed is:
An acoustic block comprising an inner panel, an outer panel having openings therethrough, means spacing the outer panel from the inner panel providing a sound trap in the intermediate part of the block, and wherein a row of the said openings in the outer panel is positioned in the center of the block, in perpendicular relation to the face of the block and the openings at the sides of the center row slope inwardly from the outer face of the block toward the center of the block.
