I've been keeping one door to Lyndhurst open to improve outgassing. Every few days I check that everything is all right. I have an ultrasound motion detector animal deterrent operating. Today it was still working, but sounded much softer, should probably replace battery soon. There was zero smell. I may close the door on Thursday because it might rain. But a little rain (as fell today) seems like no problem. Little falls inside the doorway because of the deep 18" overhang, and what little falls in, dries quickly on top of the tile with winds blowing over it.
I got up on the ladder and checked the ceiling hole next to the ceiling fan box. It looked like a 1/2" dowel would fill it just about right. Such a dowel could be cut to 1/2 thickness, and glued to the sheetrock. Gap should be left on the metal box side, with that gap filled with acoustical caulk. A layer of caulk could be put over the wood dowel piece also. And caulk must be applied all around the electrical box. Then the ceiling will be sealed. Now it's actually got significant air leakage, I'd guestimate about equivalent to a 2" hole, similar to the hole in the door that vents the entire room when the door is closed. Since I have a sealed attic, leakage is less of an issue than otherwise, but it's still an issue for air and sound quality. Sealing off the attic will prevent any outgassing from the spray foam ceiling (and other stuff up there) from getting into the room. When sealed, it will also be less able to act like resonant chamber.
I could get the 1/2" dowel tonight at Home Depot. I could see if they will cut a 1/2" piece off also.
I was thinking about having ornaments hang from the eaves to provide privacy from neighbors to the SW and W from the master bedroom window. Lyndhurst itself only needs more privacy to the north and northwest from the window. That could be provided by a line of bamboo growing to 8' along west and north fences.
