摘要： The invention relates to a window, in particular a sliding window, for closing off an open surface (102) in a wall separating the inside from the outside, and comprising an opening panel (120) and a frame (110). The window is characterized in that it comprises: "a passive acoustic silencer comprising two parallel and acoustically absorbent slides (130, 330, 340, 140) extending in a median plane normal to the open surface (102), one slide being attached to the opening panel (120) and the other being attached to the frame (110), the movement of the opening panel relative to the frame creating, between said slides, a slit having a thickness (103) equal to the window opening. The invention also relates to a system of windows for acoustic damping between the inside and outside of an open space in a wall.
