基于德国DataK ustik公司开发的CadnaA计算机辅助软件，通过两座自然通风冷却塔降噪项目，简要介绍了该软件的应用，包括数据准备、建筑物的建模及反射损失的设置、地势信息的导入、降噪措施的设置等，预测了自然通风冷却塔在治理前后对周围声环境的影响，并与现场实测值进行比较，结果表明预测值与实测值相差较小。

Two natural ventilation cooling towers were modeled and analyzed by Cadna A code developed by DataKus-tik Company in Germany. Application method of the code was introduced, including data preparation, modeling of struc-tures, determination of reflection loss, input of terrain information, and the consideration of the noise reduction measures. Noise influence of the natural ventilation cooling towers on the ambient acoustic environment was predicted. The predicted sound pressure levels were compared with the measurement data. The difference between them was found to be small.
