What is claimed is: 1. A multilayer article comprising: a support layer; and a sub-micron fiber layer on the support layer, said sub-micron fiber layer comprising polymeric fibers having a median fiber diameter of less than 1 micron (μm), wherein said polymeric fibers comprise at least 75 wei
What is claimed is: 1. A multilayer article comprising: a support layer; and a sub-micron fiber layer on the support layer, said sub-micron fiber layer comprising polymeric fibers having a median fiber diameter of less than 1 micron (μm), wherein said polymeric fibers comprise at least 75 weight percent of a polymer selected from polyolefin, polypropylene, polyethylene, polyester, polyethylene terephthalate, polybutylene terephthalate, polyamide, polyurethane, polybutene, polylactic acid, polyphenylene sulfide, polysulfone, liquid crystalline polymer, polyethylene-co-vinylacetate, polyacrylonitrile, cyclic polyolefin, or a combination thereof. 2. The multilayer article of claim 1, wherein said polymeric fibers have a mean fiber diameter ranging from about 0.3 μm to about 0.9 μm. 3. The multilayer article of claim 1, wherein said polymeric fibers have a mean fiber diameter ranging from about 0.5 μm to about 0.7 μm. 4. The multilayer article of claim 1, wherein said polymeric fibers comprise up to about 99 weight percent of two or more polymers selected from polyolefin, polypropylene, polyethylene, polyester, polyethylene terephthalate, polybutylene terephthalate, polyamide, polyurethane, polybutene, polylactic acid, polyvinyl alcohol, polyphenylene sulfide, polysulfone, liquid crystalline polymer, polyethylene-co-vinylacetate, polyacrylonitrile, or cyclic polyolefin. 5. The multilayer article of claim 1, wherein said polymeric fibers comprise polyolefin fibers. 6. The multilayer article of claim 1, wherein said polymeric fibers are uniformly distributed within the sub-micron fiber layer. 7. The multilayer article of claim 1, wherein said support layer comprises a non-woven fabric, a woven fabric, a knitted fabric, a foam layer, a film, a paper layer, an adhesive-backed layer, or a combination thereof. 8. The multilayer article of claim 1, wherein said support layer comprises a spun-bonded fabric, a meltblown fabric, a carded web of staple length fibers, or a combination thereof. 9. The multilayer article of claim 1, wherein said support layer comprises a web of bonded staple fibers, where said support layer is bonded using thermal bonding, cold-welding, adhesive bonding, powdered binder, hydroentangling, electro-spinning, needlepunching, calendering, or a combination thereof. 10. The multilayer article of claim 1, further comprising an adhesive layer on the support layer opposite the sub-micron fiber layer. 11. The multilayer article of claim 1, further comprising an additional layer over the sub-micron fiber layer. 12. The multilayer article of claim 11, wherein said additional layer comprises a color-containing layer, a non-woven fabric, a woven fabric, a knitted fabric, a foam layer, a film, a paper layer, a layer of particles, a foil layer, a decorative fabric layer, a membrane, a netting, a mesh, a wiring or tubing network; or a combination thereof. 13. The multilayer article of claim 1 attached to a substrate, said substrate comprising a wall of a building, a ceiling of a building, a building material for forming a wall or ceiling of a building, a metal sheet, a glass substrate, a door, a window, a vehicle component, a machinery component, or an appliance component. 14. A method of absorbing sound in an area, said method comprising the steps of: surrounding at least a portion of the area with a sub-micron fiber layer, said sub-micron fiber layer comprising polymeric fibers having a median fiber diameter of less than 1 micron (μm), wherein said polymeric fibers comprise at least 75 weight percent of a polymer selected from polyolefin, polypropylene, polyethylene, polyester, polyethylene terephthalate, polybutylene terephthalate, polyamide, polyurethane, polybutene, polylactic acid, polyphenylene sulfide, polysulfone, liquid crystalline polymer, polyethylene-co-vinylacetate, polyacrylonitrile, cyclic polyolefin, or a combination thereof. 15. The method of claim 14, wherein the area comprises an interior of a room; an interior of a vehicle; a piece of machinery; an appliance; a separate sound reduced area of an office or industrial area; a sound recording or reproduction area, an interior of a theatre or concert hall; an anechoic, analytical or experimental room or chamber where sound would be detrimental; earmuffs or ear covering for isolating protecting ears from noise. 16. The method of claim 14, wherein the surrounding step comprises positioning a multilayer article over at least a portion of the area, said multilayer article comprising the sub-micron fiber layer on a support layer. 17. The method of claim 16, wherein said support layer comprises a non-woven fabric, a woven fabric, a knitted fabric, a foam layer, a film, a paper layer, an adhesive-backed layer, or a combination thereof. 18. The method of claim 16, wherein the surrounding step comprises positioning a multilayer article over at least a portion of the area, said multilayer article comprising the sub-micron fiber layer on a support layer with an additional layer over the sub -micron fiber layer. 19. The method of claim 18, wherein said additional layer comprises a color-containing layer, a non-woven fabric, a woven fabric, a knitted fabric, a foam layer, a film, a paper layer, a layer of particles, a foil layer, a decorative fabric layer, a membrane, a netting, a mesh, a wiring or tubing network; or a combination thereof. 20. The method of claim 14, wherein the surrounding step comprises attaching the sub-micron fiber layer to a substrate, said substrate comprising a wall of a building, a ceiling of a building, a building material for forming a wall or ceiling of a building, a metal sheet, a glass substrate, a door, a window, a vehicle component, a machinery component, or an appliance component. 21. A method of providing a sound barrier between a sound -generating object and an area, said method comprising the steps of: providing a sub-micron fiber layer between the sound-generating object and the area, wherein the sub-micron fiber layer comprising fibers having a median fiber diameter of less than 1 micron (μm), said sub-micron fiber layer comprising polymeric fibers having a median fiber diameter of less than 1 micron (μm), wherein said polymeric fibers comprise at least 75 weight percent of a polymer selected from polyolefin, polypropylene, polyethylene, polyester, polyethylene terephthalate, polybutylene terephthalate, polyamide, polyurethane, polybutene, polylactic acid, polyphenylene sulfide, polysulfone, liquid crystalline polymer, polyethylene-co- vinylacetate, polyacrylonitrile, cyclic polyolefin, or a combination thereof. 22. The method of claim 21, wherein the sound-generating object comprises a vehicle motor, a piece of machinery, an appliance motor or other moving appliance component, an electronic device, a television, an animal, or a combination thereof. 23. The method of claim 21, wherein the area comprises an interior of a room; an interior of a vehicle; a piece of machinery; an appliance; a separate sound reduced area of an office or industrial area; a sound recording or reproduction area, an interior of a theatre or concert hall; an anechoic, analytical or experimental room or chamber where sound would be detrimental; earmuffs or ear covering for isolating protecting ears from noise.
