Construction noise from several urban construction sites damages both construction companies and residents by creating an unpleasant acoustic environment. Noise barriers can be a great option to manage construction noise at a level that satisfies both construction companies and residents when installed considering construction project conditions. This study developed an automatic decision model to determine the optimal noise barrier plan regarding health impacts, productivity, and costs. Among several mathematically formulated noise barrier plans, the optimal noise barrier plan was determined using simulated annealing with consideration of the three objective functions in the trade-off relationship. A case study was conducted to validate the feasibility of the developed model. In the case study, the optimal noise barrier plan reduced the total expenditure of the construction company by up to 2.4% (USD 170.5 for ten days) and the health impacts of residents by up to 39.5% (USD 4,020.2 for ten days). The developed model is expected to be utilized to improve the urban acoustic environment while ensuring the profitability of construction companies. Furthermore, various social problems (civil complaints, disputes, etc.) in urban areas caused by construction noise can be prevented through an improved urban acoustic environment.

来自多个城市建筑工地的建筑噪音通过营造令人不快的声学环境，对建筑公司和居民造成损害。考虑到建筑项目的条件，在安装时，隔音屏障可能是一个很好的选择，可以在满足建筑公司和居民的水平上管理建筑噪音。本研究开发了一个自动决策模型，以确定关于健康影响、生产力和成本的最佳隔音屏障计划。在几个数学公式化的噪声屏障计划中，最佳噪声屏障计划是使用模拟退火并考虑权衡关系中的三个目标函数来确定的。进行了案例研究以验证所开发模型的可行性。在案例研究中，最佳隔音屏障计划使建筑公司的总支出减少了高达 2.4%（十天 170.5 美元），居民的健康影响减少了高达 39.5%（十天 4,020.2 美元）。开发的模型有望用于改善城市声环境，同时确保建筑公司的盈利能力。此外，通过改善城市声环境，可以预防城市地区因施工噪声引起的各种社会问题（民诉、纠纷等）。
