Noise Emission During Electric Closing / Opening of a Car Window
Nach oben
In this example, the noise emissions caused by closing and opening a car window electrically are visualized. At the beginning of the closing process, the maximum noise level occurs locally at the positions where the static friction is overcome. Afterwards, the entire lower window seal emits noise. At the moment the window is fully closed, the upper seal emits noise, too. When the window is opened, the whole process repeats symmetrically.
