- 1. An optically reflective sound absorbing device comprising a sound absorbing structure, and a non-porous optically reflective sound transfer medium that is configured and arranged to transfer sound waves incident on the sound transfer medium to the sound absorbing structure for absorption thereby
-
23. An optically reflective sound absorbing device comprising:
-
a backing that comprises a support for a sound absorbing structure; a sound absorbing structure mounted on said support; a frame affixed to the backing; and a non-porous optically reflective tensioned film carried by the frame; wherein the frame is configured to provide a space between the film and the sound absorbing structure of about 1 to 5 mm, and the film is configured to transfer sound waves incident on the film to the sound absorbing structure for absorption thereby.

24. A method of making an optically reflective sound absorbing device, the method comprising:
- providing a sound absorbing structure and a non-porous optically reflective sound transfer medium; and
arranging the sound absorbing structure and sound transfer medium so that sound waves incident on the sound transfer medium are transferred to the sound absorbing structure for absorption thereby.
- providing a sound absorbing structure and a non-porous optically reflective sound transfer medium; and
-
25. A method of making an optically reflective sound absorbing device, the method comprising:
-
providing a backing; affixing a support for a sound absorbing structure to said backing; providing a frame; fixing said frame to said backing; locating a sound absorbing structure on said support so that said sound absorbing structure is located within a boundary defined by the frame and recessed from a surface of the frame opposite that to which the backing is fixed; affixing a non-porous optically reflective sound transfer medium to at least a peripheral part of said surface of the frame, and tensioning said sound transfer medium on the frame; wherein the frame is configured to provide a space between the sound transfer medium and the sound absorbing structure affixed to the backing, the arrangement being such that the sound transfer medium can transfer incident sound waves to the sound absorbing structure for absorption thereby.
