I have a window unit air conditioner in my bedroom window. I am up late nights and have just installed a home theater in there. I went outside just to see how loud it was out there and it you could hear it clearly. I think most of it is coming from the sides between the air conditioner and the window frame. What could I use to put in the window to help block the sound? My windows in my living room are single pane and I would also like to put something in them to.
