The reason of causing noise during th e course of using electricity fusion explosion machine is analyzed in thi s pa-per.Measuring and controlling nois e during the course of using electric ity fusion explosion machine is stud ied.Frequency spec-trum curve of noise source is analyze d.The cover of reducing noise is opti mized and designed.The result of measuring noise has indicated that the cover,which i s made of compound material,is effec tive sound reducing equipment.By using this cov-er,noise can be redued upwards of 20dB.
