Have you ever felt overwhelmed by the cacophony of noises going on in your own home? Maybe someone has turned the TV too loud, or the kids can’t seem to play without lowering their volume. The overwhelming effect of indoor noises can be due to echo of noises bouncing off hard surfaces in your homes; walls, floors, ceilings, cupboard etc.
Fret not however, studies have shown that green walls can change the acoustics of your home. According to a research done by University of Basque (Spain), green walls can have a weighted sound reduction index of 15 db and a weighted sound absorption coefficient of 0.40. The study also proved that the absorption coefficient increases with increasing sound frequencies and with larger greenery coverage. This gives you another good reason to have a green wall in your home if you enjoy the peace and tranquillity that nature provides!
