面向学生情绪改善的校园声景感知调查与分析研究——以四川大学望江校区为例

Investigation and Analysis of Campus Soundscape Perception for Students'Perceived Affective Improvement:Taking the Wangjiang Campus of Sichuan University as an Example

为探究大学校园声环境与学生情绪影响的关系和提高校园声景品质,文章以校园中的生活区、教学区和休闲区为研究场景,采用现场主观声景感知问卷调查的方法,对不同功能区的声源构成(Perceived Sound Sources)、声喜好(Sound Preference)、声舒适度(Acoustic Comfort)和感知情感质量(Perceived Affective Quality)的现状和预期水平进行统计和分析,旨在系统比较不同功能区大学生对环境声景感知评价的差异,以及不同功能区的声景特点,结果表明:(1)校园内不同功能区声景现状各有其特点,但学生的声景喜好大致相同;(2)生活区的声舒适度明显高于其他两类功能区;(3)3类功能区的声音感知情感质量现状水平与预期水平均存在明显差距。文章从因人、因情和因声3方面如何具体优化校园声景提出建议和思考。

In order to explore the relationship between the sound environment of campuses and the emotional impact of students,and to improve the quality of campus soundscape,the living area,teaching area,and leisure area on campus were used as research scenarios.The method of onsite subjective questionnaire survey of soundscape perception was used to investigate the perceived sound sources,sound preferences,acoustic comfort,and the current and expected levels of perceived affective quality.All the indexes above were analyzed statistically to systematically compare the differences in environmental sound perception and evaluation among college students in different functional areas,as well as the sound characteristics of different functional areas.The results show that:(1)the current situation of sound scenery in different functional areas on campus has its own characteristics,but students'sound preferences are basically the same;(2)the acoustic comfort of the living area is significantly higher than that of the other two functional areas;(3)There is an obvious gap between the current level of sound perceived affective quality in the three functional areas.Finally,the paper puts forward suggestions and thoughts on how to optimize the campus sound environment from the three aspects of person,situation,and sound.
