Greenery Barriers and Green Streets for Noise Reduction

The Green Streets contribute to the reduction of noise annoyance, especially in traffic noise. The presence of trees along the streets, and the integration of vegetation in walls, building façades and roofs increase the sound absorption, reducing the level of noise and the consequent annoyance.  Inside the cities, medium-height solid barrier can be integrated in a street by covering with vegetation, transforming it into a greenery barrier.

We are interested in the evaluation of the acoustic absorption of greenery noise barriers and the prediction of their performance in real urban situations by the aid of software for predicting environmental noise.
