I'm looking for a way to block out excessive ambient traffic noise from a window in the below room. Preferably, with the use of multiple layers of black out curtains or some real thick acoustic ones. I was imagining hanging one set on the rails pictured. And then a second rail covering most of the wall.
Has anyone had any luck or advice with this sort of thing? Any thick and affective curtains anyone would recommend? Or something non destructive I haven't thought of yet? Thanks in advance guys.
