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规范》(GBJ87-85)规定测点选择原则:若车间各处A声级波动小于3dB,则只需在车间内选择1-3个监测点,如果车间各处A声级波动大于3dB,须将车间分成若干区域,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图所示，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表面一米处，高度为半个机器设备高度，选择四个监测点。
