Background and Objectives: Noise is a common harmful physical factor in the work environment. This study sought to prioritize noise control methods using analytical hierarchy process (AHP) in a tire manufacturing factory in IranMaterials and Methods: The study, which adopted a cross-sectional, descriptive, analytical design, was conducted in the baking hall of an Iranian tire manufacturing factory in 2017. The aim was to prioritize various noise control methods using AHP. To this end, 4 criteria (namely implementation and maintenance cost, method applicability, method effectiveness and efficiency, and intervention in the process) and 8 alternatives (including reducing individuals’ noise exposure time, designing and installing sound isolation chamber for operators, using of earmuffs and earplug simultaneously, changing processes or operational procedures in machinery with excessive noise generation, forming noise control engineering teams, requiring people in charge to quickly fix the leaks and change baking press washers on time, using acoustic panels in the ceiling and walls, and designing and manufacturing silencer and nuzzle for the steam and compressed air outlet of baking press machinery) were selected. Then, to prioritize noise control methods based on objectives, criteria, and alternatives, an AHP questionnaire was developed and completed by domain experts and noise control specialists. Data analysis was performed using Expert Choice. V. 11 and Excel.Results: The results of the study showed that inconsistency rate in all caseswas less than 10%, hence the consistency of responses was approved. Based on experts’ opinion about the selected criteria, implementation and maintenance cost had the highest weight (0.481), while method effectiveness and efficiency recorded the lowest one (0.046). With regard to the alternatives, change in the process registered the greatest weight (0.193), whereas individuals’ noise exposure time had the lowest weight (0.046).Conclusions: Based on the final weights, the most appropriate noise control methods in this industry are changing processes in machinery with excessive noise generation, forming noise control engineering team, and manufacturing silencer and nuzzle for the steam and compressed air outlet of baking press machinery. Furthermore, AHP is a suitable approach for prioritizing decisions related to noise control .
