in my experience there are 2 types of people: ones that can focus with headphones on and ones that need silence. you are part of the lucky ones.

also, as far as interruptions go, acoustic interruptions are only one type of interruption. Your brain is physically wired to pay attention to things in your visual fields - it's physically wired to pay attention to people coming and going, continuously assessing the situation. just because you can function in an open space environment it does not mean that the environment is optimal.

Just a suggestion. Have you considered trying hearing protection to create a “low noise” bubble?

I have a pair of shotgun hearing protection ear muffs next to my bed. I only use them for emergencies when I really need to sleep and neighbors are partying very late. However, putting them on cuts any noise to a mumbling like in the distance.

Not the exact model or make but similar. Not electronic.

yes. and earplugs. that being said the pressure differential sucks and you will also have issues if for example you’re a side sleeper

Thanks for the follow up. Yes, the size of the hearing protection makes sleeping on the side pretty much impossible. I guess that is an acceptable tradeoff, as long as I can get to sleep.
