| Abstract: | The radiation noise of refrigerator＇ s compressor shell is analyzed in this paper by using the method of FEM and IBEM coupling under the exciting of a plane sound resource. The radiation noise after the modification of the shell shape is analyzed too and the result shows that the new shell shape can reduce the shell radiation noise around 2 000 Hz |
