Based on the noise test data of existing workshop, the noise of new packing workshop was studied. The effection of several noise control scheme was predicted by simulation and analysis method, and the control scheme five was chose finally ,by which average noise reduction was about 4.5dB,and 8h equivalent continuous A-weighted sound pressure level of the pick-up coil station and packaging machine station was 84.9dB and 83.2dB respectively, the working environment of the new workshop was effectively improved, and the investment was estimated.
