In this paper, an experimental study on the powertrain in vehicle sound power test was presented. The necessary parts retrofits and acoustic treatments for the powertrain sound power test in the vehicle were listed. The criteria and correction method of the appropriate background noise level for the powertrain sound power level test in the vehicle were discussed. The powertrain sound power tests in the vehicle were achieved in the low noise chassis Dynamometer in the semi-anechoic chamber. Based on the test results, the acoustic component contributions for the powertrain sound power levels were given .
