A WIND GENERATOR FOR MUSICAL INSTRUMENT PARTICULARLY PIPE ORGANS COMPRISES A SOUND DAMPER ARRANGED IN FRONT OF THE AIR INTAKE OF THE WIND GENERATOR. THE DAMPER COMPRISES A HOUSING THE INTERIOR OF WHICH COMMUNICATES WITH THE WIND GENERATOR INTAKE, AND THE DAMPER ITSELF COMPRISES AN AIR INTAKE WHICH IS PROVIDED WITH A FLAP OR SIMILAR OBTURATING ELEMENT, WHICH CAN BE MOVED FROM A CLOSED CONDITION UNDER THE EFFECT OF AIR FLOW PRODUCED IN THE DAMPER HOUSING, INTO A CONDITION IN WHICH THE DAMPER AIR INTAKE IS UNCOVERED TO A GREATER OR LESSER EXTENT. THE HOUSING WALL OF THE DAMPER HAS, AT LEAST LOCALLY, A DOUBLE WALL CONSTRUCTION AND DEFINES ONE OR MORE SECONDARY FLOW DUCTS WHICH COMMUNICATE FREELY WITH THE ATMOSPHERE. THE OBTURATING ELEMENT HAS A PRELOAD ACTING IN THE DIRECTION OF CLOSURE WHICH PREVENTS IT FROM OPENING UNTIL A PREDETERMINED VACUUM LEVEL IS PRODUCED IN THE INTERIOR OF THE DAMPER HOUSING.
