Maybe I just grew up in a quiet place.
We're outnumbered.
For some it is just the illusion of having more people around them, though.
I would kill for some decent high res wide fov AR glasses.
Personally I need almost complete silence in order to get anything done, his abilities in this regard always fascinated me.
It's useful for some people to have recognisable sounds going on while they work, so they have something to latch their focus if they lose it for a second. Whether that be music, or every seinfeld episode on a shuffled loop on the TV.
I have found it useful in the past to listen through every song I have on shuffle while I read, which was nice when I took a few-seconds break every couple of pages and came across a song I wouldn't have picked out otherwise. Alt-tabbing out of a podcast or something completely wrecks my focus on both for some reason though.
If it's dead quiet, I become hyper-alert to noises, to the point I can't concentrate on working.
