Abstract :
In this new era, noise pollution is very high.
The one reason for this noise pollution is noise or sound
which is generated by the exhaust system of the
motorbike. So, it is necessary to reduce the noise from the
exhaust of the motorbike. In this, original silencer reverse
engineering has done and analyse it then three
modification model of the silencer with it analysis are
done and from that results one modified silencer are
selected and forward for the manufacturing. After
fabrication of the silencer, two tests are conducted. First,
the test is conducted with original silencer then it is
conducted with modified silencer. From that data,
transmission loss of original and modified silencer are
calculated and compare it. From that, noise reduced to
5DB. Also, flow velocity of exhaust gas in original silencer
and modified silencer are also measured. In that,
conclusion is that flow of modified is increase by 11% to
original silencer and also PUC of modified silencer are
check and it is in limit as per the PUC norms.
