Abstract
A window pane fixed to an automobile via a peripheral joint forms at least a part of a wall defining a cabin of the vehicle. The window pane, at the peripheral joint, is constructed so as to eliminate at least one mode of acoustic radiance from the pane to a cavity defined by the cabin when the pane is excited by an acoustic field.
Claims8
A window pane fixed to a vehicle via a peripheral joint and forming at least a part of a wall defining a cabin of the vehicle, wherein the window pane, at the peripheral joint, comprises means for locally modifying the window pane at the peripheral joint to eliminate at least one mode of acoustic radiance from the window pane to a cavity defined by the cabin when said window pane is excited by an acoustic field.
A window pane comprising a glass sheet part to a vehicle via a peripheral joint and forming at least a part of a wall defining a cabin of the vehicle, wherein the thickness of the glass part of the window pane is displaced at the peripheral joint, and at a location such that at least one mode of acoustic radiance from the pane to a cavity defined by the cabin is eliminated when said pane is excited by an acoustic field.
