Vegetative Noise Barrier: A Sustainable Solution for Urban Road Traffic Noise Reduction in Nepal

In this report, we investigate if vegetative noise barriers can be used to treat urban road noise in Nepal. Noise pollution has grown to be a serious worry for Nepal as more and more people move to cities and the number of vehicles increases there. While they block noise well, typical noise barriers cost a lot to set up and maintain and don’t help the environment. The research assesses whether vegetative barriers, made up of trees, shrubs and greenery, help reduce traffi c noise by absorbing it, redirecting it and keeping people from hearing it. Field measurement of sound levels in chosen urban locations was combined with analyzing vegetation which clearly shows a decrease in ambient noise when barriers are in place. Besides, the research ensures that air is cleaner, the area is more eye-pleasing and wildlife is better protected which support the nation’s desire to be sustainable. Problems related to tiny spaces, routine plant care and the differences in climate are also examined. The results support adding vegetative noise barriers to city planning and noise strategies because they are less expensive to build, more sustainable and support healthier cities across Nepal.
