大学校园环境噪声监测与评价研究——以重庆医科大学为例

Environmental Noise Monitoring and Evaluation on the Campus of a Medical University

通过监测校园环境噪声水平,根据国家标准对校园声环境进行了噪声污染评价。使用NL-27噪音计,对校园8个不同功能区分别于9:00~11:00、13:00~14:00、15:00~17:00和22:00~23:00四个时间段对等效声级进行了测定。结果表明:白天校园内各个功能区噪声达标率低于夜间。其中办公、教学区和田径场噪声值昼夜都达标;厚德广场白天超标,晚上达标;校门口、学生宿舍、小吃街昼夜都超标,白天超标率低,夜晚较严重。该校园声环境质量总体不容乐观。虽然教学和办公区噪声值低于国家标准,但是学生主要活动场所和校门口交通干道旁噪声值高于国家标准,应该采取一定的措施对噪声污染进行干预,确保学校的声环境质量。

Objective： To detect the environmental noise level of campus, evaluating the extent of noise pollution according to the national standard of noise controlling in campus environment. Method： NL-27 sound level meter was used, to monitor the level of noise in eight different functional areas on campus during four time periods, ranging from 9：00 to 11：00, 13：00 to 14：00, 15：00 to 17：00 and 22：00 to 23：00. Results： Generally, the qualified rate of sound level in each functional area of campus during daytime is lower than that during night. Specifically, the sound level in the office,teaching and track areas were qualified during day and night; the sound level at the Houde square were qualified only during night,the noise level at the front gate of school, the dormitory area and the food court exceeded the designated standard level for corresponding area both in the day and at night, in which the noise is more serious during night. Conclusion： The acoustic environment quality of the campus was not optimistic. Although the acoustic environment quality was qualified for teaching area and office area, most of the time the acoustic qualitywas unquali- fiedin main student activity area and traffic artery outside of the front gate. Intervening measures should he taken to improve the acoustic environment on campus.
