This paper presents the findings of a study on the impact of traffic noise on residents living along National Highway 1A in Hue City. The results indicate that noise levels at the monitoring sites exceeded the limits of the National Technical Regulation on Noise (QCVN 26:2010/BTNMT), particularly at locations near bus stations and road intersections. During peak hours, high traffic density results in elevated noise levels. According to the survey data, 37.5% of people were affected by road traffic noise, mainly headaches and sleep problems, while the remaining 62,5% said they did not experience any health effects. In addition, noise also affects people's daily activities such as talking, phone calls, watching television, reading books, resting, and sleeping; however, the level of influence is negligible.
