With the development of collegiate ecosystem campus, quality of acoustic environment in teaching area is extensively concerned. Taking a campus of a university in Qingdao as an example, the noise characters in the teaching area were analyzed, and some representative teaching areas were selected according to the characteristics of noise source distribution. Through the noise monitoring in the teaching areas, student’s questionnaire investigation of noises in classrooms, and the analysis of the information of student’s subjective response by means of fuzzy mathematics, the noise threshold based on comfort sense in the teaching areas were determined. Finally, according to the characteristics of noise source distribution and the noise threshold, some measures for improving acoustic environment in the teaching areas of campus were proposed.
