The noise problem becomes one of the most important criterion with the increasing population density. Especially, the human life environments are seriously damaged with the increasing traffic noises which continuously occur in urban areas where the buildings are closed to the roads and high-speed railroad. And, the superficial and uniformly established soundproof walls becomes one of the elements which hindered the beauty of the cities. Also, the heat island effect and air quality deterioration are becoming seriously. So, the soundproof walls using the eco-friendly elements is demanded, but this soundproof walls is rare in Korea. this study is to develop the excellent performance of the ecotype soundproof walls which can intercept the traffic noise and improve the city environments at the same time. in order to achieve this goal, the current existing soundproof walls were invesigated and a systematic design of an eco-friendly soundproof walls was suggested. Also, computer simulations were undertaken to evaluate the acoustical performances.
