Living walls soothe our hectic lives. They not only look beautiful, clean the air, cool buildings, and support bio-diversity, a recent study from Spain proves how they absorb the harsh effects of urban noise and provide an individual oasis of calm.
A study by Spain’s Department of Thermal Engineering at the University of the Basque Country measured the sound absorption of living walls over a range of frequencies in an acoustic test chamber.
The study by Applied Acoustics concluded that :
- Green walls provide a weighted sound reduction index of 15 db.
- Green Walls gave a measure a sound absorption coefficient of 0.40.
- Green wall have significant potential for sound insulation for vegetal architecture.
Compared to other building materials, living walls offer a significant reduction in noise, with the benefits of beauty and ecological harmony nothing else provides.
