为了解噪声危害,我们对钢铁厂部分高强噪声车间的噪声进行了测试,结合工人健康检查资料作如下综合分析。 生产环境噪声 噪声级和频谱分析:钢铁厂噪声源很多,主要归纳成空气动力性噪声和机械性噪声源两种。测试结果见下表。
In order to understand the noise hazard, we tested the noise of some high-intensity noise-intensive workshops in the steel plant and combined the data of workers’ health examination for the following comprehensive analysis. Production environment noise level and frequency spectrum analysis: There are many noise sources in steel plants, which are mainly classified into aerodynamic noise and mechanical noise sources. The test results in the table below.
