Abstract: A window pane having a window sash attached thereto to reduce noise transmitted through the window pane. The window sash comprising a bracket and tuned mass damper attached to the bracket at one or more spaced intervals. The one or more spaced intervals are adjusted to tune the window sash to a targeted frequency to reduce the noise transmitted through the window pane. The targeted frequency may be the coincidence frequency of the window pane. The stiffness and/or mass of the bracket and tuned mass damper can also be chosen to reduce the noise transmitted through the window pane.

Abstract: A door assembly includes a main door body with an interior flange and an exterior flange, both extending parallel and generally away from the main door body. A door frame surrounds the door body when the latter is in a closed position, the door frame having an inner and outer flange, both of the latter extending generally toward the main door body when in its closed position. Two gaskets are provided between a flange of the door frame and a flange of the door, whereby movement of the main door body in a given direction generally perpendicular to the direction in which the flanges extend causes the gasket to be compressed.
