Attenuation of Noise using Barrier in the form of Enclosure (original) (raw)

The installation of sound barriers is feasible enough to cause a significant decrease in noise pollution on roads. This study analyzes how the noise barriers affect the sound intensity level on roads. Noise level generated by a traffic flowing across open stream is compared to that of roads provided with sound barrier. Based on the field measurements an in-depth discussion is carried out to analyze the effectiveness of installing the barriers. The main objective of this paper is to predict the sound attenuation after the installation of the sound barrier on the road side. The priority of this project is to determine whether the installation of sound barriers is feasible enough to cause a distinct decrease in noise level on the roads.
