基于Cadna/A的蓝色港湾小区改造声环境预测分析

Analysis of Noise Distribution of Community Before and After Restoration by Using Cadna/A

文章基于Cadna/A对长春蓝色港湾住区设计的噪声分布进行预测研究,建立小区声环境的三维噪声模型,评估住区改造方案对噪声分布的影响。结果表明:改造过后的小区噪声环境在噪声最高值、最小值、平均值三个指标上均有所改善,其结果对于住区的规划与改造具有重要参考价值。

Noise distributions of community in Changchun City are predicted by using Cadna/A software on the basis of a 3D simulation model. Meanwhile, assess the influence from the reform project. The results show that the noise environment of the reconstructed area has been improved on the three indexes of the maximum, minimum and average of the noise, The study might have important reference for the community design and reconstruction.
