In view of the lower frequency problem of a micro-EV, using the finite element method (FEM), the acoustic modal was calculated ,then the acoustic frequency response of the cab was made . In order to reduce the vibration of the panel which radiates the noise most, BEM was used to calculate the acoustic contribution of the main panel of the car body, then to solve it by putting up damping material on the panel. By comparing the noise response, it is found that the damping material has significantly reduced the noise of the cab.
