Based on the theories and methods of acoustic array measurement, the surface radiation noise of turbocharger was tested in the bench experiment. With the analysis of the experiment data, sound holography contour map was used to plot the noise distribution of the turbocharger. It is found that the major noise source closes to the compressor, and the maximum noise near the compressor brand. The major noise frequencies are related to the aerodynamic noise and rotating rotor vibration. These results basically coincide with the sound intensity experimental results and these results will also give help to further study of the NVH characteristic of the turbocharger.
