Abstract
The construction of apartment buildings near the road is increasing in the city. Noise insulation facilities are installed to reduce road traffic noise. The most effective is the sound proof tunnel. However, the sound proof tunnel is indiscriminately and excessively installed. Noise isolation performance and economic feasibility should be considered when installing sound proof tunnel. Based on the results, sufficient alternatives will allow for efficient designs at the same cost. This study provided an alternative to the efficient design of insulation facilities for apartment housings. It predicted the impact of traffic noise. We simulated 3D simulation of the apartment buildings. It analyzed the noise reduction effects.
