摘　　要：基于成都露天音乐公园项目周边所处噪声现状,分析了该区域的环境噪声。综合考虑周围道路的影响,根据公园及周边噪声源类型及其特点,对园区内外多个点位进行现场噪声监测。根据实测数据,结合几何声学发散衰减原理,利用raynoise计算机模拟软件对公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,针对噪声影响因素提出了相应的降噪措施。结果表明,实验和数值模拟相结合,能够较好地反映公园噪声的特点,可为今后有效开展城市公园噪声分析与治理提供参考。Based on the current noise situation around the Chengdu Open Air Music Park project,the environmental noise in the area was analyzed.Taking into account the impact of surrounding roads and the types and characteristics of noise sources in and around the park,on-site noise monitoring will be conducted at multiple points inside and outside the park.Based on measured data and the principle of geometric acoustic divergence attenuation,the Raynoise computer simulation software is used to simulate and predict park noise.By comparing and analyzing the measured data and predicted results,corresponding noise reduction measures have been proposed for the factors affecting noise.The results indicate that the combination of experiments and numerical simulations can effectively reflect the characteristics of park noise and provide reference for effective analysis and control of urban park noise in the future.
