Noise barrier as free standing living walls are constructions of baskets or different elements covered/filled with soil substrate with the function to reduce noise emissions e.g. along highly frequented roads.

Role of Nature / Mode of Action: 
Natural soil with vegetation cover (perennials and shrubs/trees) is the model for noise barriers as free standing living wall.
Technical & Design Parameters: 
The underground soil of noise barrier needs to be suitable for heavy wall elements. The design options are limited.
Conditions for Implementation: 
Green wall noise barriers need more space than non-vegetated noise barriers and some kind of (natural) water supply is needed.
Benefits & Limitations: 
Benefits: Multiple benefits, partly similar to other living walls; great enhancement of visual appearance of noise protection walls; potential for reuse of storm water Potential limitations/disservices: Success often dependent on natural precipitation
