Claim	A fabric material composite construction, for use as a filter means or media in acoustic applications also providing a protective function, wherein said construction comprises a combination of at least one nanofiber layer supported by a synthetic single-thread squarely knitted precision fabric, wherein said at least one nanofiber layer is coated on said fabric by an electro-spinning coating method and being embedded in said fabric, thereby forming a single or cohesive bound filtering means or media, wherein said nanofiber layer is made of nanofibers having a diameter ranging from 100 to 900 nm, the composite construction preventing the passage of particles having particle size of 1-2 µm. A composite construction, according to claim 1, characterized in that said nanofiber layer is coated on a single side of said fabric or on both sides of said fabric. A composite construction, according to claim 1, characterized in that said nanofiber layer is coated on said fabric after having coated on said fabric an adhesive materia A composite construction, according to claim 1, characterized in that said construction further comprises an additional fabric thereby providing a sandwich fabric arrangement including therein said nanofiber layer.
