| Abstract: | Vehicle interior structural noise caused by the vibration of car body panels directly affects passengers＇ comfort. The examination of car body panel acoustic contribution helps to determine the location of the panels which produce considerable influence on vehicle interior noise. Accordingly, the car body panels are modified in terms of the vibration characteristics and reducing the interior noise. Acoustic transfer vector （ATV）. method is used to analyze the car body panels acoustic contribution of the aluminum alloy A-type metro vehicles, and in so doing to determine the panel location which affects the interior noise. |
