However, until 2019, in Tan Tuc town, Binh Chanh district, Ho Chi Minh City, no research has been done on noise intensiy due to road traffic.- Objectives: Determination of noise intensity due to vehicles on main streets and related factors in Tan Tuc town, Binh Chanh district, Ho Chi Minh city.- Materials and Methods: This was a correlational study which measured noise intensity at 24 points of 5 major streets in Tan Tuc town, Binh Chanh district, Ho Chi Minh city. Mann - Whitney Test was used to compare differences between the noise intensity and the associated factor in special placeswhile T - Test was used to compare differences between the noise intensity and the associated factor in normal places.- Results: This study measured the noise intensitywhich was contributed from street traffic in the major streets of Tan Tuc town, Binh Chanh district, Ho Chi Minh city. The intesity wasoverthe limit of the national standard of noise in many places at different times in a week. In the special places, the traffic noise intensitywas between 76.1 - 82.5 dBA.In the normal places, the traffic noise intensity was between 76.3 - 86.6 dBA. By using Mann - Whitney Test, there was a statistically significant relationship between the traffic noise intensity in the special places and the width of the roads. Moreover, T - Test showeda statistically significant relationship between the trafficnoise intensity in the normal places and type of roads, the width of the road, the day - night and the peak hours.- Conclusion: Noise intensity due to road traffic in most of major streets in Tan Tuc town, Binh Chanh district, Ho Chi Minh city was over the limit of the national standard of noise.
