Sound attenuating air vent

Abstract

An device that allows air flow while attenuating sound for the purposes of allowing air to flow between rooms in a structure such as a house or building. The device consists of an air passageway that attenuates sound and covers at each end of the passageway. The covers allow air flow while providing an aesthetically pleasing appearance. Multiple embodiments support pre and post construction scenarios as well access to the interior of the device for cleaning purposes.

1 ) A ventilation device that facilitates the flow of air between rooms within a house or building comprising
 a. an enclosure sized to fit in interior walls typical of houses and buildings   b. the said enclosure having a chamber and a first side, the said first side defining a first aperture and the said enclosure defining a second aperture, the said first aperture and said second aperture positioned so that air enters said first aperture, normal or approximately normal relative to the said first side, through said first aperture and is redirected parallel or near parallel relative to said first side to exit said second aperture.   c. sound attenuating material placed in such a manner as to contact air flowing through said device   
     wherein the said device allows air flow while attenuating sound. 
   
   
       2 ) the device of  claim 1  with a cover over said aperture that allows air flow 
   
   
       3 ) the device of  claim 2  where said cover is removable 
   
   
       4 ) the device of  claim 2  where said cover has an access door 
   
   
       5 ) the device of  claim 1  where said chamber has baffles 
   
   
       6 ) the device of  claim 1  where said chamber consists of a plurality of smaller chambers 
   
   
       7 ) the device of  claim 1  having at least one louver that rotates to open or close air entry way to said aperture 
   
   
       8 ) the device of  claim 1  having a sliding panel that opens or closes air entry way to said aperture 
   
   
       9 ) the device of  claim 1  having a pliable material placed around said aperture forming a seal between said aperture and said interior wall. 
   
   
       10 ) the device of  claim 1  where the side defining the said second aperture is opposite to said first side wherein the air enters the said first aperture on one side of said interior wall and exits the said second aperture on the opposite side of said interior wall 
   
   
       11 ) the device of  claim 1  where the side defining the said second aperture is orthogonal or approximately orthogonal to said first side wherein an application of this configuration would include two said devices where air would flow through one said device, through the interior of said interior wall, and through the other said device exiting on the opposite side of said interior wall. 
   
   
       12 ) a ventilation device that facilitates the flow of air between rooms within a house or building comprising
 a. an enclosure sized to fit in interior walls typical of houses and buildings   b. the said enclosure having a chamber and a first side, the said first side defining a first aperture and the said enclosure defining a second aperture, the said first aperture and said second aperture positioned so that air enters said first aperture, normal or approximately normal relative to the said first side, through said first aperture and is redirected parallel or near parallel relative to said first side to exit said second aperture.   c. the said chamber constructed of sound attenuating material   wherein the said device allows air flow while attenuating sound.   
   
   
       13 ) the device of  claim 12  with a cover over said aperture that allows air flow 
   
   
       14 ) the device of  claim 13  where said cover is removable 
   
   
       15 ) the device of  claim 13  where said cover has an access door 
   
   
       16 ) the device of  claim 12  where said chamber has baffles 
   
   
       17 ) the device of  claim 12  where said chamber consists of a plurality of smaller chambers 
   
   
       18 ) the device of  claim 12  having at least one louver that rotates to open or close air entry way to said aperture 
   
   
       19 ) the device of  claim 12  having a sliding panel that opens or closes air entry way to said aperture 
   
   
       20 ) the device of  claim 12  having a pliable material placed around said aperture forming a seal between said aperture and said interior wall. 
   
   
       21 ) the device of  claim 12  where the side defining the said second aperture is opposite to said first side wherein the air enters the said first aperture on one side of said interior wall and exits the said second aperture on the opposite side of said interior wall 
   
   
       22 ) the device of  claim 12  where the side defining the said second aperture is orthogonal or approximately orthogonal to said first side wherein an application of this configuration would include two said devices where air would flow through one said device, through the interior of said interior wall, and through the other said device exiting on the opposite side of said interior wall.
