Abatement of Traffic Noise Pollution on Educational Institute and Visualization by Noise Maps Using Computational Software: A Case Study

The aim is to study the impact of traffic noise pollution on an educational institution near Nagpur–Aurangabad Highway and propose a feasible noise assuaging measure. Optimizing the suitable barrier to attaining the desired attenuation, insertion loss (IL) for varying heights was computed using specialized software Predictor LimA. Further, software mapping of worked-out data was performed to generate noise contours for scenarios before and after the installation of the barrier enabling visualization of noise extent across the study area. Noise barrier design experiment concluded that a barrier of 4 m height along the college boundary could able to provide a maximum IL of 6 dB(A). Consequently, the subsequent noise level would be in the range of 57.9 to 62.9 dB(A). The developed noise maps displayed a considerable reduction in noise levels for the proposed 4 m height noise barrier.
