The utility model belongs to the technical field of acoustics, particularly a thin whole-lighting efficient natural ventilating soundproof window composed of horizontal frames of an inner and an outer windows, vertical frames of the inner and the outer windows, horizontal bars of the outer window, vertical bars of the outer window, an air inlet, an air outlet, sound absorption sheets and a bar-shaped passage, wherein the horizontal bars of the outer window are vertically embedded between the vertical bars of the outer frame; the two to eight vertical bars of the outer window are respectively embedded between the horizontal frames of the outer window and the horizontal bars of the outer window, and between the horizontal bars of the outer window and the horizontal frames of the outer window; the outer window is divided into two to eight window sash spaces. The one to four vertical bars of the inner window are respectively embedded between the horizontal bars of the inner window and the horizontal frames of the inner window, and each inner window is divided into one to four window sash spaces; the outer frame of the inner window is fixed to the upper part at one side of the outer frame of the outer window; the window sash space at the right of the upper part of the outer window is used as the air inlet; a linear passage on the connection bottom plate of the inner window and the outer window is used as the air outlet; grooves are arranged at two horizontal frames of the inner window, and the sound absorption sheets are embedded in the grooves. When in use, the window sash at the position of the air inlet is opened outwards; then, air from the air inlet enters the air outlet to rooms by the sound absorption passage. The utility model has the advantages of simple structure, convenient operation, high soundproof quality and good ventilation effect, and has no influence on landscapes; the micro-pore sound absorption sheets of the sound absorption passage are easily.
