Traffic noise pollution at residential area

Most people are unaware of noise pollution occurring around them due to the characteristic of the pollution itself. This pollution is not visible to people’s sense and affects people based on their sound level acceptance. Since people who have high sound level acceptance are familiar with noise, thus noise pollution will not directly annoy them. This study was conducted to determine the traffic noise level at Seksyen 7, Shah Alam and its correlation with traffic volume. Since noise level will affect people in terms of annoyance and lead to health effect, the study area were chosen at intersections nearby residential area.
