Abstract : In 21st century, automobile industries are booming at an unimaginable space. An inbred snag of IC engines is that it is a main root cause of noise pollution. That is the reason mufflers are used to muffle the noise produced. The major cause of noise pollution is due to the noise. Noise pollution has hazardous effect on human health. In traffic noise, the major cause of noise is two wheeler vehicle noise. In order to minimize two-wheeler noise, we are modifying two wheeler silencer for noise reduction by introducing Absorptive and reflective Muffler or introducing new Hybrid Muffler.

Keywords :- Vehicle noise; Mufflers; Sound pressure level; Insertion loss.
