There's actually people who work night shifts, would common sense imply in their case that noise pollution in day times would be curbed by stopping traffic and all staying quiet when walking down streets?....
Common sense would make them insulate their houses.
The point is that people walking or driving past a house where someone on night shifts is sleeping aren't being unreasonable or hanging around for hours in large numbers, and so have no obligation to keep the noise of their footfall/engine down to the absolute bare minimum (although I always avoid making excessive noise just in case). Social expectation is that individuals need to travel around to get to work etc during the day and there's a certain level of noise that goes with that. It's not exactly the same as a social media 2am crowd.
A closer analogy would be if a large impromptu gathering happened during the day, every day, with no sign of it stopping. If I was a local resident that was either sleeping during the day, working at home or looking after a baby, I'd be wondering when it was ever going to end by day three.
Agree that if my career had me working nights on a regular basis, I'd insulate my house. Still seems unreasonable to those with young families, and I'd still be pissed off at the amount of rubbish, difficulty parking etc caused by an app deciding that my apartment was next to Pokemon HQ though.
