ABSTRACT

 

In this paper the effects of noise level control for 7.5 KVA diesel generator set with and without enclosure is discussed. It has been found that the noise level at zero distance with enclosure is 78.6 dB and with the recorded data graphs have been plotted , it shows a noise of 27.4 dB(A) reduction. It is discussed in detail in this paper that constructing a double wall enclosure and if the air-gap is filled with mineral wool, it can give a further 10 dB reduction.
