ABSTRACT –Sound package can effectively absorb and isolate the air borne noise, a lot of efforts have been put on the study of materials and parameters of sound package, it is difficult to predict the effects since the transfer functions of the vehicle are changing as the parts varies, but it is simple to obtain the airborne noise transfer functions of a vehicle no matter the vehicle is built or not, this paper starts with the study on different transfer functions of air borne noise, and compare the different test results, the best transfer function has been proposed finally.
