摘　　要：根据校园噪声源类型及其特点,对校园内多个区域进行现场噪声监测。根据实测数据,结合声能几何发散衰减原理,利用Cadna/A软件对校园噪声进行模拟预测。通过对实测数据和预测结果的对比分析,提出了降噪措施。结果表明,实验和数值模拟相结合,能够较好地反映校园噪声的特点,具有较强的操作性,能够弥补实验工作的不足,为今后有效地开展校园噪声治理提供参考。Based on the types of campus noise sources and their characteristics,on-site noise monitoring was carried out in multiple areas of the campus.Based on the measured data,and with the combination of the principle of geometric divergence and attenuation of sound energy,Cadna/A software was used to simulate and predict the campus noise.Through the comparative analysis of the measured data and prediction results,noise reduction measures were proposed.The results showed that the combination of experiments and numerical simulations could better reflect the characteristics of campus noise and had strong operability,making up for the shortage of experimental work and providing useful reference for effective campus noise management in the future.
