Comparison of Sound Insulation Performance of Water Drop and Trapezoidal Sound Barriers

With increasing urbanization and industrialization, noise pollution has become a significant environmental issue. This study compares the sound insulation performance of two different sound barrier designs: water drop and trapezoidal. COMSOL Multiphysics software for computational simulations is used to calculate sound transmission loss (STL). The results indicated that the water drop design provides more effective sound insulation compared to the trapezoidal model. Additionally, economic analyses suggest that the water drop design may offer long-term advantages despite higher initial costs.
