At measuring stations, 4 days of week, three time period, and 1523 measurements were recorded totally. Each measurement was recorded for 30 minutes. After transferring data to computer, SPSS and Excel software were applied for statistical analysis; also T-test and ANOVA were used for statistical tests. According to result this study the average of equivalent sound pressure level in all stations is equal to 76.28 ± 3.12 dB. There was a statistically significant difference between the mean values of equivalent sound pressure level on different roads, different weekdays and various daytimes (P<0.05).
