高校校园噪声评价——以海南师范大学南校区为例

Evaluation of Noise in University Campus——South Campus of Hainan Normal University as an Example

利用Sound Level Meter Tes1351B噪声仪对海南师范大学南校区不同功能区昼间、夜间噪声进行监测,计算了各功能区域监测点等效连续A声级(LAeq)和噪声污染指数(PN).用环境噪声标准评价法和指数评价法分别评价校园环境噪声,分析并找出出现噪声污染的主要区域.结果表明:海南师范大学南校区校园声环境整体一般,基本能满足老师、学生正常的工作、学习和生活需求;生活区和校界噪声污染比较严重.

Noise in daytime and nighttime were monitored in South campus of Hainan Normal University with Sound Level Meter model Test 1351B. The LAeq and PNwere calculated by the result of monitoring. The sound environment of the campus were evaluated with index method and environmental noise criteria evaluation method. The major source of noise and areas being affected seriously by noise have been found out and analyzed. The results indicated that acoustical environment is fine as a whole in south campus of Hainan Normal University. The normal working environment is not af- fected seriously by noise. The living area and boundary of campus are polluted seriously. Suggestions and measures were put forward to improve sound quality of the campus.
