Abstract
A method of fabricating an acoustic device includes forming a plurality of holes in a panel, disposing the panel in a support frame, and heating the panel to a temperature such that the panel sags while disposed in the support frame and each hole of the plurality of holes is modified.
Claims39
A method of fabricating an acoustic device, the method comprising:
- forming a plurality of holes in a panel;
- disposing the panel in a support frame;
- and
- heating the panel without a mold to a temperature such that the panel sags while disposed in the support frame and each hole of the plurality of holes is modified.

A method of fabricating an acoustic pane, the method comprising:
- cutting a plurality of elongated slots in a flat panel;
- disposing the flat panel in a frame;
- and
- heating the flat panel without a mold in a kiln to a temperature such that the flat panel sags while disposed in the frame and each elongated slot of the plurality of elongated slots undergoes deformation.
1 more element
An acoustic device comprising:
- a panel having a perimeter and an interior face within the perimeter, the interior face having a sagging curvature;
- and
- a plurality of holes in the interior face;
- wherein the sagging curvature of the interior face is modified by either auxetic deformation or a flap at one or more holes of the plurality of holes.
1 more element
An acoustic system comprising:
- a framework;
- and
- a plurality of panes supported by the framework;
- wherein:
- each pane comprises a face with a sagging curvature and further comprises a plurality of holes in the face;
- the sagging curvature, the plurality of holes, or both the curvature and the plurality of holes differ across the plurality of panes;
- and
- in at least one of the panes of the plurality of panes, the sagging curvature of the face is modified by either auxetic deformation or a flap at one or more holes of the plurality of holes.
