NOISE POLLUTION CONTROL BY GREEN BELT
Technology: This is an advanced technology developed by Prof. B.D. Tripathi (2007) in which noise pollution is controlled with the help plants.
Principle: Sound waves are deflected by different plant species. Reduction in the sound intensity is dependent on the leaf size, its thickness, texture, presence of cuticle on leaf and stem, canopy and fast growing rate of the plant species. Henceforth, green belt of the different plant species may be used as a tool to control the noise pollution.
Noise Attenuation: Highest reduction in noise level was demonstrated with the help of specific green belt developed by Murraya peniculata, Hibiscus rosasinensis, Cestrum nocturnum and Putranjiva roxburghi plant species.
Recognition of the Technology: Technology is published in an International Journal “Environmental Monitoring and Assessment 146, 67 – 75 (2007)” and highly appreciated by the urban people.
