Prioritizing of Noise Control Methods in the battery making industry by the Analytical Hierarchy Process (AHP)

Consideration to time constraints, implementation and funding in each industry, one of the essential strategies for managing noise control and selection the best method is to prioritize noise control methods. The aim of this study was to Prioritizing of Noise Control Methods in the battery making industry by the Analytical Hierarchy Process (AHP).

The present study was a descriptive-analytical cross-sectional study.After measurement of sound pressure level and identifying the main sources of noise pollution, Content validity index (CVI) and content validity ratio (CVR) were used to sieve the criteria and methods of noise control. Prioritization of noise control methods based on the study criteria was done by calculating the relative weight of each of them by two factors of Eigenvalue and eigenvector.

The results of the study showed that the inconsistency ratio(IR) in pairwise comparisons was less than )10%( in all cases and the consistency of the answers was confirmed. Based on the results, among the study criteria, the acoustic efficiency criterion of method with weight(0.1810), and Among the proposed methods of noise control, the method of controlling the exposure time to noise and training of workers with weight(0.1732) had the highest priority.

Findings showed that in the studied battery making industry, the best criterion in noise control is the safety of the noise control device. Also based on the results, controlling the duration of exposure time to noise and training workers in conditions of high noise exposure was the best method to noise control in the battery making.
