One of the most important roles of green space is decreasing the noise pollution. The noise pollution is affecting the human life due to its increase result of urban areas development. This research was conducted in order to study the effect of different hardwood and conifer tree species, green space, physiographic features and land use in decreasing the noise pollution in Northern Iran. The measurement was performed in summer season with an amplifier and a sound meter of HD9019 model in different types including 8 stations in 25, 50 and 100 meters distance between noise sources and sound meter with 5 replications. The results were analyzed using one way ANOVA and Duncan multiple range test. The results showed that the slope has a significant effect on decreasing noise pollution. The trees density showed a significant relationship with decreasing noise pollution. The most decreasing in noise pollution was finding in hardwood stand with 47.2 db decrease.
