Abstract :

Background and Objective: This descriptive-analytical aimed to detect and identify the amount of noise pollution in a number of workshops in Delijan city, by measuring levels of noise pollution. Material and Methodology: The measurements for 55 workshops and 728 stations were performed using SLM2237 (B&K brand). Findings: By examining the results obtained and comparing them with the standard limits for each location, which vary according to the type of use, it was found that 7.5% of the stations are in the safe area, 57% in the precautionary area and 35.5%. % Were in the danger zone. Also, in this study, Moreover in order to investigate the effects of noise pollution on individuals, a relevant questionnaire was prepared, and after randomly selecting the study population, the questionnaires was administered in person to different age groups within the population (about 500 people) in the areas where noise pollution levels were measured.   Discussion and Conclusion: According to the results, the noise level in small workshops is higher than the standard. Therefore, upon while analyzing the obtained results, strategies for controlling noise pollution according to the type of use.
