Measuring and Accessing the Environment Noise in the Campus of Northwest Minorities University

The definition,characteristics,harms and subjective parameters of the environmental noise were described in this paper.We analyzed the noise pollution status in the campus of Northwest University for Nationalities and also made the comparisons between the inner part of the campus noise conditions and its exterior part by the noise monitoring of the university.The results of this experiment showed that the noise environment of the whole campus was not satisfaction,and the average rate of the standard in 6 measuring points is just 19.3%.Finally,some proposals for environmental noise reduction had been presented.
