摘　　要：目前高校提倡建设生态校园,其教学区声环境质量也逐渐引起广泛关注。以湖北省某高校为例,根据声源选取具有代表性的教学楼,通过实地监测与问卷调查,采用模糊数学法处理调查对象对教室声环境的主观反应信息,计算得出教学区上课期间舒适度阈值为48.2 dB,采用Ridit分析对调查结果进行检验,验证计算所得舒适度域值是合理的。The high educational school in our country is advocating constructing the ecological campus at present, in which the noise environment quality in the teaching area is getting more and more concerned. Regarding some high school in Hubei province as the example, seclecting typical teaching building based on the noise source, through monitoring noise environment and investigating subjective response information, using the fuzzy mathemantics to deal with all the subjective information from the investigated classroom, the comfortable threshold of the noise environment in the teaching area is calculated and the result is 48.2dB, and the Ridit analysis is used to verify the rationality of the comfortable threshold.
