Abstract

Background and Objectives: Since Noise Pollution as an important environmental problem, affects people’ s health, the present study aimed at evaluating Noise Pollution level and the pattern of its changes in the area. Materials and Methods: In the present cross-sectional study, the equilibrium sound levels (Leq) were measured in 16 stations, during fall-winter of 2016 and spring-summer of 2017, in the morning and evening peak traffic times at all weekdays using the KIMO-DB100 Sound Level Meter. The data were analyzed using the Geostatistical Analyst tool and based on Inverse Distance Weighting (IDW) interpolation method. Results: The results showed that the highest and lowest Leq were related to working days and Friday, respectively. The equivalent sound level in winter is as a minimum 1 dB higher and in summer as a minimum 1. 5 dB lower than the other seasons. The minimum equivalent sound level was 56. 1 dB throughout the sampling period and the maximum was 86. 75 dB. The extents of equivalent sound in all stations were more than standard limit of residual areas (55 dB). Conclusion: According to the results, Noise Pollution is spread almost in all areas and hours of Zone 1-Region 6 of Tehran. This issue illustrates the necessity of applying Noise Pollution control technologies in this region.
