Traffic noise pollution at residential area

Abstract

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. The data of traffic noise level and traffic volume were collected representing weekday and weekend for each intersection. Three (3) data collection session were conducted for each day, which is in the morning (0730-0830), in the afternoon (1230-1330) and in the evening (1700-1800). The collected data were then being analysed and compared with the standard limit set by the Department of Environment Malaysia (DOE) to check whether the noise level at the study area comply with the limit recommended.

It is also anticipated that low concentration, fatigue, doubts, confidence loss, irritability, misunderstandings, low work ability and others are the variety of psychological, physical and behavioural issues as a result of noise pollution, derived from vehicles [13].…”

Effect of Thickness and Perforation Size on the Acoustic Absorption Performance of a Micro-Perforated Panel

“…According to the Malaysian Department of Environment's Guidelines for Environmental Noise Limits and Control, the maximum permissible sound levels for low, medium, and high-density residential areas range from 55 dBA to 65 dBA [2]. From a 2018 study conducted at two road intersections leading to nearby residential units in Shah Alam, the highest recorded noise level in a day was well above 90 dBA which greatly exceeded the allowable limit [3]. On top of that, Malaysia has an annual growth rate of approximately 6 percent in terms of the number of registered private vehicles [4].…”
