Analysis on the Spectrum of Enterprise Noise of Ferroalloy
Yang Qiang-li · Journal of Chongqing Institute of Technology · 2003
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.
