Recently I've been trying a different approach to surviving all the clunks and bangs from various neighbours.

I've used noise sources in the past but I've always tried to turn them off whenever possible so that I could have at least a few hours, minutes, of peace.  Now I'm just leaving the noises to run 24 hours a day.  Currently in the bedroom/office I have rain sounds, plus thunderstorm sounds plus a fan running.  I spend most time in this room.   When I'm in other rooms I turn on additional things - the sound machine in the kitchen and/or the sound machine in the living room.  Sometimes the kitchen exhaust fan as well and the bathroom fan.  If it's warm enough that I'm forced to have the balcony door open as well I put a really loud fan right in the doorway (which also helps a bit to pull cooler air in).  I never use the "solarium" so there's nothing in there.

I try to vary the sounds a bit since I find that I can get used to them and then I start to hear the sounds under them.

It's not perfect, I can still sometimes hear bangs and such but with the constant noise they don't send me into a startle reflex as easily.

One downside is that I can only listen to music or watch TV using headphones or earbuds.

I seem to be adapting and I am sleeping better - I often now sleep until 7 a.m. instead of being jolted awake several times from 5:30 on.
