> 4. Scaffolding being put up or taken down. Incredibly noisy, actually has to be done fairly regularly [...] The fact that it has to be done fairly regularly is not inevitable. It's a consequence of some arguable laws in some cities (NYC for example). Living in Paris, I can't recall ever being disturbed by scaffolding being put up or taken down. The scaffolding I see generally stays up for months at a time until the work is finished, which means it's only being put up and taken down once. And it's not frequent to see scaffolding. A big item missing from that list is mopeds (and, to a lesser extent, other loud 2-wheelers, which are less frequent). A lot of food delivery workers use those all day and night round, and they are very loud. As others have said, someone's list is heavily influenced by where they live. All the items you listed are generally not a big issue to me (mopeds, general ICE noise, honking and random alarms are the main culprits). Edit: clarification, "ICE" means internal combustion engine here. Electric vehicles are nearly silent at low speed and don't contribute to noise.
