Environmental Noise from Construction Site Power Systems and Its Mitigation

S. Elancheliyan , Dr J. Krishnakumar

Generator sets for power system is one among the important equipment used in the construction industries, used in large numbers and as clusters and also located very near to the work area. The noise levels produced by these generators are much higher than the permissible limit. In the first step of this paper assesses the potential noise emissions associated with two unclosed caterpillar power generators used in a construction site. In the second step combined noise effects of generators and other activities are studied over a 12-hour period to establish background environmental noise levels. The study shows large number of construction workers working nearby generators are exposed to 100 dB (A) or more noise. The chain of noise control at the source- along the noise path or at the receiver and what effective steps could be done to mitigate the noise exposure at each stage is considered.
