Green facades reduce noise between 2 to 5dB

Green facades act as barriers against noise produced by traffic and urban noise pollution. The vegetation attenuates the sound thanks to its porosity and ability to vibrate. The density of plants on the wall determines its ability to reduce noise. The green facades not only eliminate annoying noise, but also contribute with relaxing sounds of motivation of leaves, branches and the birds that inhabit the vegetation.
