基于Cadna/A的高校公寓声环境模拟与优化策略研究OA

The university apartment is a main place for the learning and living of the university students,and its acoustic environment quality is not only related to the learning efficiency and mental health of university students,but also has great significance for the sustainable development of the campus.Taking the student apartment of Taiyuan University of Science and Technology as an example,this paper focuses on the current situation and optimization strategy of the sound environment of the university apartments,and analyzes the characteristics of the apartment sound environment through on-site measurement data collection by combining with the simulation analysis of Cadna/A and building sound environment SEDU software,and proposes the targeted optimization measures.The results show that the outdoor noise pollution of each apartment is more serious than that of the indoor one,and the noise pollution at night is more serious than that of the day.The four optimization strategies are arranged in order of noise reduction from high to low:the introduction of"natural sound",the control of the road traffic flow in the campus apartment area to 80%of the original,the replacement of steel doors,and the addition of green belts.The results provide an important reference for improving the acoustic environment quality of university apartments.
