Standing in the living room's double-doorway, looking across the front part of the foyer into the family room, (looking across towards the right side of the house). Another set of double-doors can close off the family room from this foyer as well. If both sets of double doors and hallway doors are closed, each side of the house is just about sound-proof from the other. When I used to have church committee meetings in our living room, shutting the doors allowed my family to still use our family room/kitchen/bathroom side of the house, (eating/watching TV, etc.) with no noise interference to my meeting.
