I think the superhearing power is going to be different than you think. You can already hear your clothes rubbing against skin, the air conditioning blowing, etc. Your brain is pretty good at filtering those out. Now, the conversations will be more difficult, but think about your experiences at a party. Most of the time you can hear another group’s conversation if you listened and focused on them, but you can tune them out (most of the time, ignoring the cocktail party effect stuff for now). Unless you have focus issues already, it wouldn’t be a big deal. The issue would be the initial period where your brain has to learn what exactly to filter out. Right now, a rustle to my right would be a bad sign, and hearing a rat crawling through the wall would freak me out. After a few weeks though, I bet I’d have adjusted.
I remember one of the tidbits I picked up from a psychology textbook was that people who were worse at knowing if their partner was lying were in happier relationships. Turns out that white lies are important.
