In order to analyze the acoustic design process of sound barriers, survey analysis of traffic noise in the region around the residential buildings adjacent to an avenue was conducted. Based on the data obtained, three preliminary designs of sound insulation reflective barriers with different top structures were done for this region. To verify the result, acoustic software of Virtual. Lab Acoustic was applied to simulate the noise control performance of the three sound barriers. The simulation results show that the design of the vertical sound barrier can meet the practical noise reduction requirements effectively.
