| Abstract | ||
| This study was conducted to know the effect of using type of trees to reduce noise level inside cities around the streets, which are; Cupressus sempervirens ,Eucalyptus camaldulensis , Olea europaea and Myrtus communis. The distance of trees 1 and 2 rows , the distance between the noise level and sensitive device 5 , 10 , 15 m. The statistical results showed significant effect of each factor and their interaction on noise reducing, and the great effect recorded by using Myrtus communis trees with two rows more than one row, the noise level was decreased gradually with increasing the distance between voice resource and sensitive to be 64.37 DC, as a difference 27.38 DC, from the Level ( without planting ) near the street . | ||
