Use of greenery noise barriers in urban planning improves aesthetic and perception aspects. A new modular-based greenery wall has been acoustically characterized. Vertical greenery systems show a significant noise attenuation on the urban road. Barrier with vertical greenery is better than traditional reflecting barriers. The proposed greenery system shows an improvement with a pair of parallel barriers.
