4 Claims. (Cl. 181-33) This linvention refers generally to acoustical panels for room ceilings and the like yand more particularly to an acoustical panel having means for refllecting sound waves passing through the sound absorbing portion of said panel back into said sound absorbing portion.
One of the prime purposes for the installation of an acoustical ceiling isof course to -absorb as much of the sound waves impinging on said ceiling as is possible. In the past sound waves coming in contact with an acoustical panel passed through said panel including the sound absorbing means therein in a more or less direct path. The lowering of the sound level by acoustical panels has in 'the past therefore depended to a great extent on the thickness of the sound absorbing means since the sound waves pass in one side of the absorbing means and out the other. With the usual sound absorbing means the sound passing out of the absorbing means after having passed therethrough is still objectionable. This is especially true in the case of suspended acoustical ceilings where the chamber above thefsuspended ceiling acts as a duct to spread sound waves received through the only partly eifective acoustical material into areas where the sound waves are objectionable. Through the use of an acoustical panel having an attenuating pan attached to the back thereof to reflect the sound Waves passing through the sound absorbing means back into the sound absorbing means many of the objectionable qualities of previous acoustical panels can be eliminated.
One of the essential objects of this invention is therefore to provide an acoustical panel having means for reflecting sound into a sound absorbing means.
Another object is to provide improved means to attenuate sound waves in a suspended ceiling system.
Another object is to provide an improved acoustical panel which may be installed and removed as a complete unit.
Another object is -to provide an acoustical panel through which sound transfer will be a minimum.
Another object is to provide an acoustical panel which is simple in construction, easy to manufacture and efficient 1n use.
Other objects, advantages and novel details of construction of this invention will be made more apparent as this description proceeds, especially when considered in connection with the accompanying drawings wherein:
FIGURE 1 is -a plan view of the normally exposed surface of an acoustical panel according to this invention.
FIGURE 2 is a side view of the panel of FIGURE l.
FIGURE 3 is an enlarged longitudinal section of the panel in FIGURE 1 along the line 3 3.
FIGURE 4 is an end view of the panel of FIGURE 1.
FIGURE 5 is an enlarged cross section of the panel of FIGURE 1 along the line 5 5.
FIGURE 6 lis -an enlarged perspective of one end of the panel of FIGURE 1 partly in section to better show the construction of said panel.
The invention consists of a rigid substantially at supporting pan 2 having perforations 4 therein and upturned sides 6, 8, 10 and 12, a sound absorbing material 14 inside of pan 2 and -an attenuating pan 16 placed on top of the sound absorbing material 14 and adapted to connect with pan 2 whereby sound waves passing through pan 2 and sound absorbing means 14 and impinging on attenuating pan 16 are reflected back into sound absorbing means 14.
The supporting pan 2 in the embodiment of the invention shown in FIGURES l-6 is a at rigid pan 2 of rectangular cross section. The pan 2 is approximately three times as long as it is wide and is divided into square sections by grooves 18. The square sections have perforations 4 therein covering substantially the entire surface thereof. The pan 2 has sides 6, 8, 10 and 12 which have been formed by turning up the Ifour sides of a at rectangular sheet of rigid material. Sides 6, 8, 10 and 12 are provided with grooves 20 parallel to the plane of pan 2 which produce shoulders 22 on the interior of sides 6, 8, 10 and 12, The shoulders 22 -are used to secure the attenuation pan 16 to the supporting pan 2 in a manner later described. The sides 6, 8, 10 and 12 of pan 2 have cut out sections 24 at third points along the length thereof and cut out sections 26 at the four corners thereof to facilitate connection of the supporting pan 2 in a complete acoustical system such as a suspended ceiling (not shown). 'The pan 2 may be made of anyrigid material such as enameled metal or plastic. The surface of the material should be capable of being made a variety of colors and should be easily cleaned.
Sound absorbing material 14 which is placed inside of supporting pan 2 may be a mat of synthetic material such as fine plastic or glass fibres or it may be wool or wood fibre. The material shown at 14 is a rectangular mat which substantially fills supporting pan 2. A loose sound absorbent material may also be used. According to this 'invention no particular requirement as to the quality or quantity of sound absorbent material to be used is made.
The attenuating pan 16 provided according to this invention is a at pan as shown in FIGURES 3, 5 and 6. The pan 16 may be formed from a flat rectangular sheet of material by bending the edges thereof down to form an obtuse angle as shown at 28 and then turning the bent down edges up to form lips 30. The attenuation pan 16 may be of any material capable of retaining its form and capable of reflecting sound waves impinging thereon. Metal or plastic material may be used for the attenuation pan with acceptable results. The function of the attenuation pan 16 is to reflect sound passing through the supporting pan 2 and the sound absorbing material 14 and impinging on pan 16 back into material 14 where it is further absorbed.
The supporting pan 2 and the attenuation pan 16 may be manufactured by known means such as the stamping of sheet metal or the molding of plastic. The sound absorbing material may be produced by pressing fibrous material into mats by a process also well known. The mat or other form of sound absorbing material 14 is then placed in support pan 2. Attenuation pan 16 is placed on top of material 14 and the edges of material 14 are compressed as shown at 32 by the edges of the pan 16. The lips 30 of the pan 16 are forced over shoulders 22 on sides 6, 8, 10 and 12 thereby locking the support pan 2, the sound absorbing means 14 and the attenuation pan 3 in assembly. The assembly as shown best in FIGURE 6 may be installed or removed from an installation as a unit.
In use a plurality of the assembled panels may be arranged to form for example a suspended ceiling. The hanger wires, channel support means and clips necessary for such a system are well known and form no part of this invention and therefore are not shown. With the suspended ceiling in place sound waves within the area covered by said ceiling will strike against the panels. The sound waves will pass through the support pan 2 and through the absorbing means 14 where they will to a large extent be attenuated. The sound passing through the absorbing material 14 may however still be objectionable. In the usual acoustical system such sound is allowed to pass into the space above the suspended ceiling and travel through this space to other areas where it is unwanted.
According to this invention however the sound waves passing through the sound absorbing material 14 strike attenuation pan 16 and are reflected back into the material 14 where they are further absorbed. The pan 16 thus contines the sound to a great extent to the area where it is created and causes the sound to be further deadened by passage through the absorbing material 14 again.
The drawings and the foregoing specification constitute a description of the improved acoustical panel in such full, clear, concise and exact terms as to enable any person skilled in the art to practice the invention, the scope of which is indicated by the appended claims.
