An innovative design and development of noise barrier with newly composite mix of acoustic panel.

Urban dynamics and anthropogenic interventions led to an increase in noise pollution levels, with relevant implications for worldwide healthcare. Structures created to lessen noise pollution from traffic, industry, or other sources are known as noise, sound, or acoustic barriers. The research paper presents a unique design and development of noise barrier with newly composite mix of acoustic panels and vegetative cover augmenting noise attenuation and aesthetics. The barrier provides a symmetrical design around the vertical axis, hence assures utilization of both faces of the barrier. Additionally, the barrier hosts multiple slots to accommodate multi-material acoustic panels based on diverse noise frequencies and environmental conditions. The barrier integrates movable noise caps at 45°, 90°, 180°, and 270° angles for further attenuation and diversion of noise. A drip irrigation system within the soil box ensures optimal plant growth and stability to barrier. Experimental studies showcase the barrier's performance and its effectiveness in diverse noise scenarios. This innovative development provides a comprehensive solution towards noise mitigation through compact, customizable and sustainable green noise barrier.
