요약2 Soundproof tunnels block direct sound and minimize reflected sound, resulting in an excellent noise reduction effect. However, soundproof tunnels have not been thoroughly examined in terms of economic feasibility, stability, and usability. In particular, their high cost of installation and heavy weight are considered disadvantages. Therefore, it is essential to ensure economic feasibility and reduce the weight of soundproof tunnels. However, in South Korea, panels used in soundproof tunnels can be used only if they satisfy the required standards (sound transmission loss). Therefore, in this study, while the acoustic performance standards (sound transmission loss) for soundproofing panels were not met, a lighter and thinner membrane material was proposed for a soundproof tunnel, and its noise reduction effect, weight, and economic feasibility were examined. To ensure marketability, the noise reduction effect of the soundproof tunnel with the membrane structure was investigated using 3D modeling and real-scale experiments, and the findings were compared and analyzed with existing noise barriers.
