Visual and Aesthetic Performance of Plants in Reducing Effects of Noise pollution

Due to the rapid industrialization, urbanization and transport systems, noise pollution has reached to a disturbing level over the past few years. Plants have been suggested as an affordable and natural construction to mitigate outdoor noise pollution in comparison to concrete, metal, plastic and other man-made materials. The goal of noise control is to promote relaxation, satisfaction and well-being in urban residents. Green belts in residential areas are known as one of the most important and effective methods to reduce noise pollution caused by road traffic in urban areas. A row of trees may be an effective technique compared to other barriers in decreasing noise pollution. In recent years, several methods have been used for measuring the effects of landscape elements on noise reduction. The results showed that green elements not only mitigate noise pollution but also play important role in creating attractive scenes for people which may enhance human tolerance for noise pollution. In addition, organization of plants and their aesthetic values may have positive role on noise reduction.
