Road noise reduction apparatus and installation method therefor

An apparatus for reducing road noise, the apparatus being seated on a plurality of buried grooves spaced at regular intervals and in a direction in which vehicles travel on a road surface, the apparatus comprising:

• pipe-shaped bodies each having a hollow formed in the corresponding body to pass through a part of one end and a part of the other end of the body, a fitting groove formed toward an inside of the one end, a shim protruding outward from the other end, and a communication portion formed at a side portion of the body to allow the hollow to communicate with the outside, the communication portion comprising a cylindrical shape having a diameter ranging from 4 mm to 10 mm, wherein distal ends of the communication portions open to an outside comprise filtration films, and wherein the distal ends of the communication portions are positioned 2 mm to 3 mm lower than the road surface;
• wherein the plurality of bodies are connected to each other such that the shim is fastened to the corresponding fitting groove, and wherein an interval between the communication portions, which are configured by connecting the plurality of bodies to each other, is 40+/−10 mm;
• wherein a space between the buried grooves and the apparatus for reducing road noise comprises a filler material adapted to reduce road noise, and wherein the communication portions are not filled with filler material, and
• wherein a heating wire is provided inside and/or outside the body.
