金华职业技术学院JINHUA COLLEGE OF PROFESSION AND TECHNOLOGY噪声控制技术实验报告专业环境监测与减排技术班级环保123组号五组组长冯侃成员金政博娄三元成绩2014 年 6 月27 日实验一校园噪声监测实验一、实验目的：1、训练学生独立完成环境噪声监测任务的能力；2、使学生学会熟练声级计的使用方法；3、训练对非稳态的无规则噪声监测数据的处理方法，对监测结果的分析和评价能力。

二、实验任务：1、确定环境噪声监测方案；2、对环境噪声进行监测；3、数据处理，以合理的方式表示监测结果；4、写出环境监测实训报告，并对环境质量进行简单评价。

三、实验地点：金华职业技术学院四、实验组织：将整班学生分为17组，每组3个人，一个组长。

学生在指导老师的带领下进行具体操作。

五、实验内容和过程：1、制订噪声监测方案（1）将学校（或某一地区）划分25×25m的网格，测量点选在每个网格的中心，若中心点的位置不宜测量，可移到旁边能够测量的位置。

（2）每组3人配置一台声级计，顺序到各网点测量。

（3）读数方式用慢档，每隔5秒读一个瞬时A声级，连续读取200个数据。

读数同时要判断和记录附近主要噪声来源（如交通噪声、施工噪声、工厂或车间噪声、锅炉噪声…）和天气条件。

2、数据处理环境噪声是随时间而起伏的无规律噪声，因此测量结果一般用统计值或等效声级来表示，本实验用等效声级表示。

（1）将各网点每一次的测量数据（200个）顺序排列找出L10、L50、L90，求出等效声级Leq，再将该网点一整天的各次Leq值求出算术平均值，作为该网点的环境噪声评价量。

（2）以5dB为一等级，用不同颜色或阴影线绘制学校（或某一地区）噪声污染图。
