Well you got balls growing in an apartment complex my friend......I couldn't do it........but enclosing your fan will reduce noise and you can go to home depot buy you some wood make a frame to fit over the window make a cover for the frame out of wood or panda film or painters plastic(with panda film or black or white painters plastic it is much easier to cut a hole for the adapter than cutting a whole in wood)....get a duct adapter screw it on the wood frame...you keep your blinds on the window place the frame over the window and everything looks normal from outside..you simply keep the window cracked so the air has somewhere to go....I have this type of set up on my window...
