I’ve lived in high-rise buildings in Seattle where the walls were effectively soundproof. Your neighbors could be as loud as they wanted to be and you never heard them. It took some heavy crashes on the floors above for you to hear the dull thud. Quality of construction matters a lot. Making apartment buildings highly insulated sound-wise is old science, not magic.

Even dry walls can be made virtually sound proof. If you look at the pdf below (it's in German) on page 49, you can see that noise reduction of almost 80dB is possible. This is impressive. For reference, a very simple drywall has a noise reduction of roughly 45dB. https://www.knauf.de/wmv/?id=1112 https://www.knauf.de/wmv/?id=1112 (link updated, thanks for pointing this out)

    It happened like this: Clicked on the google search result, file opened in browser, blindly copied the link from address bar. Thanks and sorry.

Soundproofing eats a lot into square metres. It's one of the biggest luxury in highrises.
