There are many factors that affect the acoustic comfort evaluation of library outdoor spaces, and the sound environments in the libraries' outdoor spaces have been surveyed in terms of soundwalk, questionnaire and building physical parameters' measurement in five campuses of three universities in Shanxi. The results suggest that sound source type has a great influence on acoustic comfort evaluation, and it also affects the relationship between sound pressure level and acoustic comfort evaluation. There is a positive correlation between landscape evaluation and acoustic comfort evaluation, and people have a higher preference for quiet sound environment, and for a sound environment with a comfortable background sound, the choice of preference is more diversified. This paper also analyzes the relationship between the overall evaluation of building physical environment comfort and the physical quantities, and these physical quantities are the main factors that affect the overall evaluation of comfort but not all, and there are other factors that will affect the overall evaluation.%影响图书馆室外空间声舒适度评价的因素较多,本文采用声漫步、问卷调查和建筑物理参数测量的方法,对山西省三所高校共五所校区的图书馆室外空间的声环境进行了调研.结果表明,声源类型对主观声舒适度评价有较大影响,还会影响到声压级和主观声舒适度的关系.景观评价和主观声舒适度评价之间有正相关关系,人们对安静的声环境有较高的偏好,而对于有舒适背景声的声环境,喜好性的选择则表现的较为多样化.本文还分析了建筑物理环境舒适度整体评价与各项物理量主观评价之间的关系,这些物理量是影响舒适度整体评价的主因子,但还有其它因素会对整体评价产生影响.
