At times in my life, I used headphones a lot. Open office type scenarios definitely remain one of those times. I am in one, but it's low population. None of us care, and one of us likes to drop some music. It's reasonable, so we all get along on that, but I digress.
There is a skill or some kind of adaptation to noise. I got it raising the kids.
Prior to them, I had trouble focusing with noise. About the middle of that journey, I became able to watch a TV program, for example, on moderate volume, with all of them getting after whatever it was.
Dad... Dad... DAD!!!
Huh?
:D
I can still do it, and can do it when I want, focusing on whatever I want. Can be in a noise filled room, and focus on a conversation nearly buried in the noise. Can be writing code, or drawing models with the world crashing around.
Or, I can give all that focus, and then it's distracting, but maybe in a good way, as in maybe I should be aware of what is this noise and why it's noisy.
Now I notice today people raising kids, they have screens, headphones, etc... We did not have that, and had a small house.
Perhaps adaptations go the other way too! Extreme noise sensitivity?
There should be another piece, "What happens when you always hear your kids?"
