工业企业的噪声等值线可以定量描述工人在作业场所的噪声暴露情况。但在实际工作中，根据既有的噪声测量方法，如GB/T 50122《工业企业噪声测量规范》，能够获得作业场所中的若干个点的噪声情况，但没啥不能形成等值线以表征噪声的空间分布形式。使用 NoiseAtWork，能根据噪声点的数据绘制其分布图，具有一定的借鉴意义。 http://bbs.zywsw.com/forum.php?mod=viewthread&tid=3343 《工业企业噪声测量规范》面向工业企业噪声测量人员。为统一工业企业所有生产环境和非生产环境的噪声测量方法，便于对工业企业噪声进行评价和控制设计，特制定《工业企业噪声测量规范》。编号为GBJ122－88，自1988年12月1日起实施。本规范适用于工业企业生产环境、非生产环境与厂界的稳态噪声和除脉冲噪声以外的非稳态噪声测量。 http://www.zgjzsd.com/product.asp?id=1361 http://www.amazon.cn/工业企业噪声测量规范/dp/B003I4ED1M 噪声对钻井工人听力影响的调查 http://www.doc88.com/p-199104420181.html

Macao (or spelled "Macau"), a famous tourism and gambling city in Asia, has the second highest life expectancy in the world and is one of the very few places having a "very high Human Development Index" in Asia. It is thus not difficult to understand why there is a rapidly growing demand for better and … Continue reading Sound tracing device. Small and good looking. Liked by the Monte Carlo of the Orient.
