This paper describes the application of an acoustic intensity measurement method to high-frequency interior noise. Technical problems in applying an averaging technique via surface scanning to high-frequency interior noise were conquered, and detailed quantitative contribution analysis of interior surfaces was made possible. Based on the analysis of a small passenger car, the effectiveness of additional noise control treatment can be roughly estimated, and an acoustic confort of the car was improved by a minimum additional treatment required.
