| 摘 要： | 随着高校生态校园建设的发展，教学区环境噪声的质量逐渐引起各高校的广泛关注。以山东省青岛市某高校为例，根据声源分布特征选取具有代表性的教学区。通过对教学区的实地噪声监测和对学生上课期间噪声舒适度的问卷调查，运用模糊数学的方法处理调查对象对环境噪声的主观反应信息，计算得出教学区上课期间的舒适度阈值。并依据噪声源分布特征和舒适度阈值，提出改善教学区环境噪声的措施。

| Abstract: | 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. |
