The window is one of the main components of the high speed train car body structure through which noise can be transmitted. To study the windows' acoustic properties, the vibration of one window of a high speed train has been measured for a running speed of 250 km/h. The corresponding interior noise and the noise in the wheel-rail area have been measured simultaneously. The experimental results show that the window vibration velocity has a similar spectral shape to the interior noise. Interiordoi:10.1088/1742-6596/744/1/012141 fatcat:3v6q656hxrf4hgo3fvo4ouvpri
