摘　　要：利用Cadna环境噪声模拟软件的交通噪声预测模型,建立某居住小区的声环境三维仿真模型,预测和评价不同降噪措施的降噪效果并进行比较,选出经济有效的降噪方案,为居住小区的交通噪声评价及环境规划提供相应的依据和技术支持。With acceleration of urbanization, influence of traffic noise on urban acoustic environ- ment becomes larger and larger. Reduction of the impact of traffic noise on residential areas with some effective measures is the key point for urban acoustic environment protection. Prediction and assessment of the impact are of significance in practical applications. In this paper, a 3D simulation model for a residential quarter is built by using Cadna software. The effects of some traffic noise reduction schemes are predicted and evaluated. In comparison of these effects, more economical and effective schemes can be selected. The method and results given in this paper provides some data for traffic noise assessment and environment planning of residential quarters.
