山东建筑大学校园周边交通噪声影响模拟分析

Analysis on Effect Simulation of Traffic Noises Around University Campus of Shandong Architectural University

大学校园周边的城市道路交通噪声直接影响校园声环境质量,并可能干扰正常的教学和生活。为探讨外部交通噪声对大学校园声环境的影响,选择紧邻城市主干道的山东建筑大学校园作为研究对象,根据周边交通噪声实测数据,并利用噪声预测仿真软件Cadna/A,计算昼间和夜间的校园噪声分布情况,进行校园声环境质量的评价与分析。

The traffic noises of city road around the university campus cause the direct impact on the sound environmental quality in university campus and could disturb the normal teaching and living.In order to discuss the impact of outside traffic noises on the sound environment in university campus,the paper selects the university campus of Shandong Architectural University as a research object.Based on the survey data of the surrounding traffic noises,the paper uses the noise to forecast the simulation soft ware Cadna/A and to calculate the noise distribution of university campus at daytime and night as well as to carry out the evaluation and analysis of the sound environmental quality in university campus.
