A case study on traffic noise control by using timber barrier wall

| 要約: | This research project looks into the existing noise levels (decibels, dBA) due to traffic of a school compound located at one of the busiest streets in Kuching City and to theoretically estimate the probable traffic noise levels reduction in the school compound after the introduction ofa timber noise barrier wall.
The existing noise levels at the classrooms, offices and dormitories of 5MB St. Terasa (except Point Y) are above the Community Noise Standards -During weekdays, the Existing noise levels at all points (except Point Yare above the Community Noise Level) and during weekeods, the Existing noise levels at all points, (except Points X and Y) are above the Community Noise Level.
The proposed timber noise barrier wall would result in a sustainable reduction in the noise levels ranging from 2 dBA to 19.0 dBA depending on the locations (distances) from traffic noise source and the proposed noise barrier wall. With the construction noise barrier wall, the predicted highest noise levels during weekdays at some of the points with the compound are approximately 4.5 dBA above the standards, and the predicted highest noise levels during weekends at some points would be marginally above (1.0 dBA to 2.5 dBA above) the Community Noise Standards «65 dBA). |
