Zusammenfassung:	High density polyester sound absorption composite fiber material and a manufacturing device thereof are provided to stick a thin synthetic resin sheet to the backside of a high density polyester sound absorbing plate, thereby blocking airflow with the surface of a wall while saving porosity for soundproof(sound absorption). High density polyester sound absorption composite(10) comprises porosity sound absorption base material(20), and a synthetic resin sheet(40). The density of the porosity sound absorption base material is 150 Kg/m^3~350Kg/m^3 based on complex polyester fiber material. The synthetic resin sheet is adhered to one side of the porosity sound absorption base material. The synthetic resin sheet is PET(Polyethylen Terephthalate) or OPP(Oriented Polyprophylene).
