齐鲁理工学院校园冬季周末声环境质量评价

Evaluation of Soundscape Quality in QIT Campus in Winter

于2017年12月的四个周末,通过观察法和实地勘测法对齐鲁理工学院校园内典型监测点进行了声环境监测,给出了各监测点不同时间段等效声级数据分析。结果表明:校园周末声环境变化规律与校门外车流量的变化规律和学生周末生活规律呈现一致性,昼间校门口全天等效声级超过I类声功能区噪声限值,而运动场、生活区也有半数或以上监测时间段噪声超限;夜间除小树林外所有监测点噪声超限。根据以上结果,结合大学校园周末学生学习、生活娱乐的需要,建议通过控制车辆鸣笛、加强校园内师生声景环保意识教育的方法解决噪声污染,并提出了提升校园整体声景设计的建议性方案。

During the four weekends of December 2017, the acoustic environment monitoring and analysis of typical monitoring sites in Qilu institute of technology campus were carried out through observation and field survey. The re suits showed that the variation law of campus weekend sound environment is consistent with the law of traffic flow outside the school gate and the law of students＇ weekend life. The equivalent sound level at the gate of the school all day exceeds the noise limit of class I sound function area, while the sports ground. In the living area, the noise was o ver half of the monitoring period, and the noise of all the monitoring points was out of the limit at night except for the mangroves. The equivalent sound level data of each monitoring point in different time periods are also given in this paper. According to the above results, combined with the needs of college students studying on weekends, life and entertainment, it is suggested to solve the noise pollution by controlling vehicle sirens and strengthening the environ mental awareness education of teachers and students in the campus. Also, a proposal to improve the overall sounds cape design of campus has been put forward.
