ABSTRACT
With the rapid development of China's economy and road traffic, the number of motor vehicles in China is increasing year by year, and traffic noise pollution is becoming more serious. Many colleges and universities in our country are located around the urban traffic trunk road, and the campus acoustic environment is seriously affected by the traffic noise. Taking Xuchang University as an example, this paper monitors the traffic noise around and inside the campus according to the relevant standards of noise measurement, uses the equivalent continuous sound level method for acoustic calculation, evaluates the traffic noise monitoring results, and uses the significant difference analysis method to analyze the resulting data, the distribution law of traffic noise inside and outside the campus at different monitoring points and the time distribution characteristics of traffic noise inside and outside the campus in different periods and different days are obtained. Finally, the test results and the actual situation of a university campus is combined, this paper puts forward corresponding suggestions and measures the impact of campus traffic noise on the campus acoustic environment, to provide a reference for the design and implementation of noise reduction measures for the university campus acoustic environment.
