PURPOSE: A noise prevention mat and a producing method thereof are provided to prevent the separation phenomenon among layers forming the mat, and to improve the durability of the mat by maintaining the harmlessness to human body. CONSTITUTION: A noise prevention mat includes a foamed layer(10), a soundproof layer(20), and a combination layer(30). The foamed layer is obtained by foaming more than one polymer selected from a polystyrene resin, ABS, a polycarbonate resin, polyvinyl chloride resin, or a vinyl chloride resin. The foamed layer is attached to the bottom of the soundproof layer, and includes an embossed surface with plural concave and convex units on one side. The soundproof layer is produced with thermoplastic polyurethane in a plate shape. The combination layer combines the foamed layer and the soundproof layer by the following steps: coating the combination layer on the upper side of the foamed layer, and heat-drying the combination layer at 80 deg. C for 20-30 seconds; melting the combination layer at 200-300 deg. C for 2-3 seconds to attach the combination layer to one side of the soundproof layer using a compress roller; and cooling the combination layer at 20 deg. C for 3-4 seconds.
