摘要
通过对重庆市某道路某处居民楼所存在的噪声污染情况进行实际监测,根据声屏障声学设计的步骤设计出适合该区域的三个不同顶部造型的声屏障,采用声学软件Virtual.Lab Acoustic对三种声屏障的降噪效果进行模拟,对模拟结果进行分析;确认直立型声屏障的设计可满足要求。
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.
