A REVIEW ON A NOISE REDUCTION SYSTEM IN IC ENGINE

The study focused on practical methods of reducing noise levels in automobile engine. Noise reduction is one of the highest prior targets for IC engine development because of the more and more strict engine noise limits. After burning the fuel the many poisonous exhaust gas such as CO2, SO2, NO2, are generated, such types of harmful exhaust gases are generate noise and air pollution. In this paper the noise measurement of IC engine is described by different method like as acoustic intensity and lead covering technique described. Muffler or silencer is a device which is used for reducing the amount of noise emitted by the exhaust of an internal combustion engine. It is an acoustic soundproofing device designed to reduce the noise of the sound pressure created by the engine.
