铁合金企业噪声频谱分析

Analysis on the Spectrum of Enterprise Noise of Ferroalloy

运用噪声频谱分析方法对铁合金企业噪声进行了分析。实验选用9种设备,分为3组进行实验。结果表明:铁合金企业噪声能量比较高,有44％的设备噪声超标;从频段上分析,铁合金噪声多属于中、低噪声。

This paper uses the method of noise spectrum analysis to analyze the enterprise noise of ferroalloys. In the experiment, nine kinds of equipment are chosen and divided into three groups. The findings show that the energy of the enterprise noise of ferroalloys is relatively high with the noise of 44 % equipment exceeding the standards, while the spectrum shows that the noise of ferroalloys belongs to medium and low noise.
