Study of the relationship between urban morphology indicators and noise pollution in District three of Tabriz city (Manzariyeh and Emamiyeh neighborhoods)

The main purpose of this study is to study the relationship between urban morphology and noise pollution in the three regions of Tabriz (Imamiyeh and Manzaria neighborhoods). Data collection From the study area, audio data were collected in 45 shifts in the morning (7 to 10) and night (19 to 22) at 45 points in the study area. Audio data was collected using the Decibel X application. The results show that the average sound in the morning is 87.06 dB and the standard deviation is 10.16. Also, the average sound in the night interval is equal to 90.08 decibels and the standard deviation is 9.28. It is observed that the average of both mentioned intervals is higher than the standard. Based on the analysis of the average sound by the user, the terminal with the average sound of 95.52 decibels and the standard deviation of 2.94 had the highest average sound during the day. In the night interval, the terminal with the average sound of 95.81 decibels and the standard deviation of 3.43 has the highest average sound. Also, based on the standards presented in the section on theoretical foundations, it is observed that all applications are higher than the standard sound level. Wilcoxon test was also significant at the level of 0.000 which showed that the average sound in the study range for morning and night is higher than the standard 75 decibels.
