PROBLEM TO BE SOLVED: To simplify the shape of a fixture by miniaturizing and making it lightweight, cut a manufacturing cost by reducing the number of components and assembling manhour and improve damping properties. SOLUTION: This soundproof cover is formed of a sheet-like noise barrier layer 1 composed of a soft elastic body and a sound absorbing layer 2 integrally joined to the back side of the noise barrier layer 1. A fixed adapter part to a noise source 4 has at least a part of the sheet metal-like fixture embedded in the noise barrier layer 1. Since the fixture 3 can be arranged each at the fixed adapter part to the noise source 4, the fixture 3 can be miniaturized by dispensing with a connecting part. In addition, the damping properties of the fixture 3 are upgraded as it is embedded in the noise barrier layer 1 with damping properties. COPYRIGHT: (C)2004,JPO&NCIPI
