Abstract
An acoustic insulation curtain is composed of a number of long, relatively high mass optically transparent acoustic barrier sheets, having longitudinally extending central portions covered with panels of acoustic absorber material. The adjacent barrier sheets overlap one another. In some embodiments they are mutually spaced and also overlap portions of absorber panels of adjacent sheets. Absorber panels may be vertically discontinuous in a staggered relation from one panel to another to provide a circuitous sound absorbing air flow path from one side of the curtain to the other.
Claims24
An acoustic strip curtain comprising
- a plurality of elongated curtain strip assemblies secured to and suspended from a support, all assemblies of a group of said assemblies hanging in side-by-side relation, each assembly of said group comprising
- a flexible acoustic barrier sheet having first and second longitudinally extending outer sections and a longitudinally extending inner section,
- an absorber panel of acoustic absorber material secured to said inner section of said sheet and extending longitudinally thereof, said panel having a thickness greater than the thickness of said sheet and having laterally facing longitudinally extending edges,
- each outer section of a group of said barrier sheets overlapping an outer section of an adjacent sheet for substantially the entire length and width of such outer sections, and
- each sheet of said group having a longitudinally extending edge portion positioned adjacent an edge of the panel of an adjacent assembly of said group, whereby sound passing between overlapping outer sections passes around an edge of a barrier sheet in proximity to an absorber panel.
An acoustic strip curtain comprising
- a plurality of elongated curtain strip assemblies, each said assembly comprising
- a flexible acoustic barrier sheet, and
- an absorber panel secured to an intermediate area of said sheet and extending from upper to lower portions thereof,
- means for suspending said assemblies to hang in side-by-side relation with portions of adjacent barrier sheets overlapping one another and with laterally outer portions of one barrier sheet in close proximity to edges of the absorber panel of each adjacent barrier sheet, whereby sound passing around the barrier sheets is guided in a path closely adjacent to an absorber panel.
