Analysis on control of rail noise in Jakarta

Abstract

The goal of research was to determine the scale of exposure caused by trains, especially in office buildings around railroad tracks. This research involves direct measurement, namely by measuring the rail equivalence index (LEq). The results of the measurement of the noise level for 2 days was 83 dB(A) which means it exceeds the standard noise level that has been set; 65 dB(A). Therefore, consideration is needed involving noise control in office buildings. Noise control focuses on the mass buildings that are formed in accordance with the influence of the wind, in which the shape of the building can accommodate wind flow in controlling railroad noise. From the research that has been done, simulated the shape of the box building and terracing. In conclusion, the form of terracing is the most effective building in reducing noise, since it has wider shading zone.
