Noise control program for oxygen-making machines
工业用制氧机噪声控制方案

A great deal of oxygen is produced during the process of steel-making. Great noise is occurred around the inlet of oxygen-making machine because of high air speed. It is harmful to human health and the environment. The noisy source of oxygen-making machine is analyzed in this paper. Based on the field investigation, the design program to reduce noise for oxygen-making machine is given. Through testing, the noisy value handled at boundary of this factory reaches the requirement of national standard.
