My room has 9' coved ceilings, hardwood floors, a very large picture window, and an arched opening to another room. The wife will not allow too large of a rug on the floors so I've had to do some careful sound suppression work. The rug I picked is nice and thick, I had my wife buy new curtains for the room (which she was more than willing to do) as long as they were very thick (she bought 2 thin sets and sandwiched a very thick but ugly set in between) and did some corner treatments as well as having mostly stuffed upholstered furniture bar the leather couch. The corner treatments were re-covered by my wife to match the room.
