The harm of noise to the human was discussed, and the present situation of noise and noise reduction measures in hammer forging workshop were studied. Through monitoring the noise level in the hammer forging workshop and the dose of noise exposure to operation personnel in working days, the noise level in the hammer forging workshop was higher than that in the national standard by comparing the test results with relevant noise standards, and noise control was needed. By installing the 〖JP3〗muffler in the air hammer,connecting the exhaust pipe into the ground and other measures,the hammer running noise was reduced effectively. Then, the central air supply of three gas furnaces was converted into single air supply by a frequency conversion fan, and the noise of the fan was reduced from 110 dB(A) to 79 dB(A). Furthermore, the gas furnaces were optimized and modified to reduce the gas furnace noise from 85 dB(A) to 75 dB(A).In addition，feasible measures for
reducing nosie were proposed in the forging workshop from aspects as equipment modification, low-noise equipment application, mechanization, automatic remote operation, etc.
