Introduction: exposure to noise pollution leaves Different effects on human. Goal in this Paper is the prioritizing methods of control and reduce noise pollution in Larestan cement Factory using analytical hierarchy process (AHP). Methods: For screening criteria and methods used in AHP technique, Delphi method was used. After polling of 15 experts, 8 criteria and 9 methods was selected from their consensus. Then, in order to prioritizing methods of reduce and control noise pollution, carried out Paired comparison of the methods and criteria, by experts using Analytical Hierarchy Process. Results: result of paired comparison of criteria show that initial investment cost was the most important criteria with the relative weight of 0.247, satisfaction from using of method, Account for the least important with the relative weight of 0.035. A paired comparison of methods according to the target of selecting control methods show that Personal exposure to noise Control method with the weight of 0.224 .was the first priority, and Insulation of building’s Method with the weight of 0.067 was the last priority. Conclusion: Because of personal exposure to noise control method obtained as the best method of controlling noise pollution in this Factory, ACGIH instruction about the time of noise exposure in the workplace suggested to directors.
