This is a truly informative article @praditya! The crucial element of sound (acoustics) definitely cannot be ignored in order for built environments to be experienced well. My favorite solution in your post is the Green Wall because it serves a double purpose. Not only does it dampen noise pollution, but also freshens up the indoor air quality and provides healing effects as a Biophilic design benefit for the occupants. Call me a nature-biased person as this is one of my lifelong advocacies. Thank you for your remarkable contribution. Happy Thursday!
