Abstract

A noise reduction apparatus can include a frame and multiple spaced apart panels positioned adjacent to each other. Each of the panels or only one of the spaced apart panel elements may have holes therein to receive acoustic waves for absorbing the waves between the panels. The panels can be attached to a frame or other connection structure so that the arrangement of panels can be hung over a work space or positioned in a work space (e.g. in a wall, formed as a partition or wall, included as part of shelving, etc.). The panels can also be incorporated into a light fixture that may hang from a ceiling or be attached to some other type of support (e.g. a table, a base, etc.). The panels can be composed of glass, wood, or other type of material.

First claim

What is claimed is:

1. A noise reduction apparatus comprising:
a first glass panel element having holes defined therein; and
a second glass panel element positioned adjacent and spaced apart from the first glass panel element to define a gap between the first glass panel element and the second glass panel element, the second glass panel element having holes defined therein, the first glass panel element and the second glass panel element positioned to define exterior surfaces of the noise reduction apparatus, the holes of the first glass panel element being in fluid communication with the gap to direct acoustic waves into the gap for absorbing sound within the gap to reduce audible noise within a work space in which the noise reduction apparatus is positionable, the holes of the second glass panel element being in fluid communication with the gap to direct acoustic waves into the gap for absorbing sound within the gap to reduce audible noise within the work space in which the noise reduction apparatus is positionable,
a frame and/or a plurality of connectors connected to the first glass panel element and the second glass panel element such that the first glass panel element and the second glass panel element are positionable within a room of a building adjacent a work surface of furniture within the room of the building or within the room of the building adjacent to the furniture.

2. The noise reduction apparatus of claim 1 wherein the frame or the plurality of connectors connected to the first glass panel element and the second glass panel element comprise:
an upper frame element, the first glass panel element attached to a first side of the upper frame element and the second glass panel element attached to a second side of the upper frame element, the upper frame element attached to the at least one mounting device to position the upper frame element below a ceiling and above the furniture within the room of the building;
a first connector positioned in the gap and a second connector positioned within the gap;
the first connector extending between the first glass panel element and second glass panel element adjacent a first side of the first glass panel element and adjacent a first side of the second glass panel element; and
the second connector extending between the first glass panel element and second glass panel element adjacent a second side of the first glass panel element and adjacent a second side of the second glass panel element.

3. The noise reduction apparatus of claim 2 wherein the first side of the first glass panel element is opposite the second side of the first glass panel element.

4. The noise reduction apparatus of claim 1 , comprising an upper frame element attached to a light emitting device, the first glass panel element attached to a first side of the upper frame element and the second glass panel element attached to a second side of the upper frame element, the light emitting device positioned between the first glass panel element and the second glass panel element so that light is emittable within the gap.

5. The noise reduction apparatus of claim 4 , wherein the gap is open at a bottom of the gap between a bottom of the first glass panel element and a bottom of the second glass panel element.

6. The noise reduction apparatus of claim 1 , wherein the frame is comprised of:
a first frame member having a first groove and a second groove;
a second frame member having a first groove and a second groove;
a first edge of the first glass panel element within the first groove of the first frame member, a second edge of the first glass panel element within the first groove of the second frame member; and
a first edge of the second glass panel element within the second groove of the first frame member, a second edge of the second glass panel element within the second groove of the second frame member.

7. The noise reduction apparatus of claim 1 , wherein the frame is comprised of:
a first frame member having a first groove and a second groove;
a first edge of the first glass panel element within the first groove of the first frame member; and
a first edge of the second glass panel element within the second groove of the first frame member.

8. The noise reduction apparatus of claim 1 , wherein the connectors extend between the first glass panel element and the second glass panel element within the gap, the gap being defined such that at least one peripheral edge of the gap is open.

9. The noise reduction apparatus of claim 1 , wherein the first glass panel element and the second glass panel element are arranged to define a tile and the frame includes a subframe element that defines a side of the tile.

10. The noise reduction apparatus of claim 9 , wherein the frame is attachable to a rail positionable adjacent the work surface.

11. The noise reduction apparatus of claim 10 , comprising an inter-tile connector positionable adjacent to the subframe element.

12. The noise reduction apparatus of claim 1 , wherein the noise reduction apparatus is configured as a free standing partition, a free standing booth, a booth, or free standing furniture.

13. A noise reduction apparatus comprising:
a plurality of first glass panel elements having holes;
a plurality of second glass panel elements having holes, each of the second glass panel elements spaced apart from and positioned opposite a corresponding one of the first glass panel elements to define a gap therebetween;
a frame and/or connectors attached to the first glass panel elements and the second glass panel element so that the gaps are in communication with each other and form a cavity, the holes of the first glass panel elements and the holes of the second glass panel elements in communication with the cavity such that acoustic waves passing through air external to and adjacent the noise reduction apparatus are passable into the cavity via the holes of the first glass panel elements and also the holes of the second glass panel elements for sound absorption.

14. The noise reduction apparatus of claim 13 , wherein the gaps are defined such that one or more peripheral edges of the gaps are open.

15. The noise reduction apparatus of claim 13 , wherein the frame is positionable adjacent furniture inside a room of the building or on a work surface of the furniture inside the room of the building.

16. The noise reduction apparatus of claim 13 , wherein the connectors comprise:
a first connector connecting a respective one of the first glass panel elements and a respective one of the second glass panel elements such that the first connector is within the gap between the first and second glass panel elements to which the first connector is connected and extends with that gap between a first side of the first glass panel element and adjacent a first side of the second glass panel element; and
a second connector connecting a respective one of the first glass panel elements to a respective one of the second glass panel elements such that the second connector is within the gap between the first and second glass panel elements to which the second connector is connected and extends between the first glass panel element and the second glass panel element adjacent a second side of the first glass panel element and adjacent a second side of the second glass panel element.

17. The noise reduction apparatus of claim 13 , wherein:
the frame comprises an upper frame element having a first groove and a second groove spaced apart from the first groove;
an upper edge of each of the first glass panel elements positioned wit
