Abstract
High speed train interior structural noise which caused by vibration of car body panels influence passengers ride comfort directly. The car body panels’ acoustic contribution analysis can determine the location of the panels which affect considerably the interior structural noise. Then that modifying the car body panels with a clear aim can improve the vibration characteristics of car body panels to reduce the interior noise. Using acoustic transfer vector method, the car body panels’ acoustic contribution of the high speed EMU were analyzed to determine the location of the panels which affect considerably the interior noise.
