摘要：

以重庆某 TOD 项目为研究背景，综合考虑道路噪声、轨道交通噪声等进行区域声环境研究。采用现场实测和仿真模拟相结合的方法，通过实测数据对仿真模型进行拟合修正，对区域内各建筑测点进行预测分析，并提出针对性的降噪措施。研究结果表明，采用 Cadna / A 软件结合现场实测数据进行修正后，其模拟精度可达到 98%以上，能够有效模拟研究区域的声学环境；通过分析道路交通、轨道交通及两者叠加作用下的环境噪声，确定道路交通是影响区域声环境的主要因素，而轨道交通因设计时考虑了隔声和减振措施，影响较小；针对超过标准限值的楼栋，采取了主动降噪和被动降噪相结合的措施，结果表明，这些措施能够有效改善区域内声环境。

Taking a TOD project in Chongqing as the research background, a regional acousticenvironment studywas conducted by comprehensively considering road noise, rail transit noise, and otherfactors. Using a combination of on,site testing and simulation, the simulation model is fitted and correctedbased on the measured data. Predictive analysis is conducted on various building measurement points inthe area, and targeted noise reduction measures are proposed. The research results show that after usingCadna / A software combined with on,site measured data for correction, the simulation accuracy can reachover 98%,which can effectively simulate the acoustic environment of the research area. By analyzing theenvironmental noise caused by road traffic, rail transit, and their combined effects, it is determined thatroad traffic is the main factor affecting the regional acoustic environment,while rail transit has a relativelysmall impact due to the consideration of sound insulation and vibration reduction measures in its design.For buildings that exceed the standard limit, a combination of active and passive noise reduction measureshave been taken, and the results show that these measures can effectively improve the acousticenvironment in the area.
