Noise barriers are highly beneficial in mitigating the emitted noise from the traffic.Īlberola J, Flindell IH, Bullmore AJ (2005) Variability in road traffic noise levels. Therefore, it requires a coherent strategy for long-term measures intended at minimizing exposure of noise hence providing much more comfort to live, work, and shop near high-traffic roads. In contrast, some communities which are adjacent to roads are suffering from high noise levels in the ambience. The Indian government is working on mitigation strategies of noise pollution as well as abiding laws regarding noise standards for the zone (residential, industrial, commercial, and silences) wise. Noise pollution levels are high from prescribed noise limits in most of the Indian metropolitan cities. gives high noise attenuation along with low-cost efficiency. For transparent barriers, perceived loudness and noise annoyance are assessed lower than that for opaque barriers and utilization of waste materials viz. Based on the review study, T-shaped barriers with a soft top surface are found to be efficient at noise attenuation. The review analysis of research papers demonstrates that the acoustic performance of barriers is dependent on different shapes, materials, and textures as well as onsite geometry. The efficient acoustic performance of noise barriers possessing different shapes and materials including waste materials is reviewed for field implementation to achieve the low-cost sustainable noise barrier application in the Indian context. The acoustical material can curtail the quality of sound or enhance the dispersion, depending on the application being considered. The acoustical properties of a barrier are highly dependent on the physical properties of the material and the internal structure of the material. ![]()
