I'd almost compare it to gender. Yes there's a spectrum, but the outer areas are very lumpy. In the case of sensitivity to office noise, the only aspect I see as intersecting with extro/intro traits would be chitchat. Everything else seems like it would come down to distractibility level, which I don't think is tied to those traits at all.

I'm just glad so many managers are cool with responsible use of headphones & noise cancellation approaches these days. Certain tasks simply require more focus.
