The acoustic shutter assembly (1) includes at least one window pane (2, 3) arranged in a frame (4). At least one ventilation duct (7) is arranged in the frame between an outer ventilation opening (8) and an inner ventilation opening (9), extending between a first layer of sound absorbing material arranged at an inside (5) and a second layer of sound absorbing material arranged at an outside. A number of acoustic reflectors (12) in the form of plate material are arranged between the first and second layers of sound absorbing material so that the ventilation duct is separated into a number of respective ventilation channels (13) formed between the acoustic reflectors. Each ventilation channel changes direction at least once between the outer ventilation opening and the inner ventilation opening, thereby at least substantially blocking any linear path from the outer ventilation opening to the inner ventilation opening.
