噪声监测设计方案
机电系实训基地
躁声监测
课程：
躁声污染控制技术
班级：
环境监测与治理技术081班
组别：
第四组
成员：
一、方案制定
1，第四周（9月20号--9月26号）接受并分析任务,利用网络及图书馆资料查阅相关内容。
2，第五周（9月27号--10月3号）进行实地考察,确定监测方案并实施监测。
3，第六周（10月27号--10月3号）对监测数据进行分析并进行降噪设计。
4，第七周（10月4号--10月10号）整理监测成果，并将其设置成Word及PPt形式递交老师审阅。
5，第八周（10月11号--10月17号）展示设计成果。
二、方案设置及监测点选取
1，生产环境噪声监测
根据?
工业企业噪声控制设计标准?
（GBJ87-85）规定测点选择原那么:
假设车间各处A声级波动小于3dB,那么只需在车间内选择1-3个监测点,如果车间各处A声级波动大于3dB,须将车间分成假设干区域,使任意两个区域的声级波动大于或等于3dB,在每个区域里分别设置1-3个监测点。
根据实地监测将整个实训基地划分为三个区域如下图，在每个区域内均布置三个监测点，如平面图所示。
测量高度在人耳附近。
2，厂界噪声监测
因为实训基地东侧为大学生后动中心，南侧为六教，西侧为农田，北侧为汽车系实训基地，将厂界监测点布置在敏感区，即东侧及南侧，在东侧布置两个监测点，南侧布置一个监测点，其位置如图一所示。
监测点距厂界一米，监测高度>1.2m。
3，机器设备噪声监测
由于车间内设备较多，所以仅选择了一台机器进行监测。
因为机械设备尺寸大于一米，根据相关规定其监测点选择在据设备外表一米处，高度为半个机器设备高度，选择四个监测点。
三、平面图及布点设置
