1. Modern properties' roofspaces are built with freeze blocks, dividing properties . Older ones have bricks. That maybe the reason of the noise travelling.Seems to be a combination of two things.
1 - Properties not been sound proofed, I remember on one occasion I tried to get police intervention they pretty much told me, a lot of the issues are down to lack of soundproofing in properties. Which does make some sense, when you think about houses which would have been originally built to house one family and then later converted to flats.
2 - People been inconsiderate or even mentally deranged. The property above me I think has been used for work purposes multiple times, one lady who lived there was using work tools on a daily basis, there is DIY, and there is something else. Probably worst neighbour ever had.
The worst types of noise for me are the ones that are sudden, and obviously at night instead of in day, so bangs, drills, etc. Especially bad if there is a period of lull thats maybe a minute or two, but then suddenly starts again as means body cant adapt at all.
2/ Many people are selfish and have zero consideration about their neighbours/households nearby
