Acoustic Window (Baffle Type)

Acoustic Window (Baffle Type) basically comprises two layers of windows which can be aligned in a way that the pane of inner sliding window is behind the outer opened window, such that the former can act as a baffle to screen off the noise from entering into the room. The other side of the outer layer should have fixed glazing or openable window to be kept closed during noise reduction mode. As noise can still be transmitted into the room, either directly or through multiple reflections of the window elements, absorbent may be applied on the reflecting surfaces (e.g. inner frame or panes of air gap) to enhance noise reduction effectiveness.
