Abstract:
1. A sound-deadening retention system comprising: at least one transparent acrylic sheet having a top surface and a bottom surface, that includes a combination of at least one embedded metal cable and synthetic polymer threads; and a synthetic polymer layer between a surface of the metal cable and the transparent acrylic matrix, a surface of the synthetic polymer layer that faces the metal cable covers at least ninety percent of the metal cable, wherein the metal cable extends from a first end to a second end of the transparent acrylic sheet, wherein a distance between a first end of the metal cable and the top surface is different from a distance between a second end of the metal cable and the top surface, wherein an elevation of the metal cable sags at a middle portion thereof, wherein at least one synthetic polymer thread of the synthetic polymer threads has a maximum deviation of at least 1 mm from a theoretical straight line drawn between ends of the at least one synthetic polymer thread, and wherein a first and a second layer of synthetic polymer threads are included in the acrylic sheet, and the polymer threads in the first layer form an angle of 90° with respect to the polymer threads in the second layer, and the synthetic polymer threads and the metal cable form an angle of 45° with respect to one another.
