A---a fan on. I can't sleep without a fan, both for noise and air circulation. I need to have moving air near my face while I sleep or I feel suffocated.
E for sure. I find it hard to sleep unless it's very quiet. I also need it to be as dark as possible.
I don't mind a fan running, however, white noise like that is ok.
A and D...sort of.
My husband needs "white noise" so we have an air purifier in the room that makes a "fan" noise. I don't like the feeling of air flow from a fan so the purifier was our compromise.
And I need TV to fall asleep, I need the distraction, but as I feel myself drifting off, I turn it off.
A fan on. I have to block out my upstairs neighbors. I think when I move into my house in two weeks, I'll still have the fan on because it will block out any unexpected sounds in the house that could wake me up.
A (kind of) and E. I'll put on rain sounds if I'm feeling too wired or stressed, but since I've gotten a cat, I've been wearing earplugs, so silence is the best.
I have an air purifier that provides a bit of white noise and when I do laundry, I put a fan on to it to dry it quicker, but I don't hear those anymore!
