Abstract : The automobile exterior noise was predicted by near-field acoustic holography (NAH) and spatial transformation of sound field (STSF) method. The basic theory of the spatial transformation of sound field was elaborated. A measuring system of near-field acoustic holography was constructed, and the error of the NAH measuring system was adjusted. The NAH data at the both sides of the vehicle were measured on a drum tester in a semi-anechoic room at the condition of Gear 2 and 55 km/h. The program of STSF was written according to the basic principle of STSF, and the sound fields of the transformati
