The effect of artificial and natural vegetation in green walls on noise pollution (Case study: Valiasr Abhar St.)

Due to the increasing density and presence of cars in crowded areas, noise pollution is one of the serious problems today. In the direction of sustainable urban development, the confrontation with this problem is felt more than before. According to the theoretical foundations in this research, in the first step, descriptive-analytical method has been studied in previous research studies on reducing noise pollution and green walls. In the second stage, the construction and simulation of a pattern of green cover using natural greenhouse and artificial plants as sound insulation has been done and then tested to reduce noise pollution. To obtain data on the effectiveness of plant sound insulation, the 1150tes sound level gauge was used and measured at different points and distances. Using analytical software, the data are analyzed and the results show that green walls have a positive effect on preventing the penetration or reflection of noise pollution into the environment and the use of natural plants wider and larger than Artificial vegetation performs better. The use of vegetation in green walls for urban design reduces environmental damage.
