Hence, reducing the noise and its cause is very important to the extent. Heavy truck produce more noise compared to minitrucks as they are having heavy duty engine below the cabin. But still working of minitrucks to reduce noise level is a challenging task. In this study acoustic materials are used to reduce the noise level inside the Tata Ace mini truck of 702 CC engine and the results are discussed.
