I'm born and raised here and I understand how OP and others feel about us Swiss.
During my stays outside Switzerland I noticed much more tolerance and laisser-faire
, in both ways: freedom to act/listen to music late etc.. and in return
acceptance towards critics/complains from others and immediate cooperation.
Here it's different: social relations are defined by rules you learn to stick to from a young age ... So listening to loud music/tv/party eg. after 11pm is considered by many Swiss as a rule-break, rude, arrogant, selfish and anti-social. The reactions of the "victims" is proportional - as the way they feel: they call the police. As they feel "ignored" by their neighbours, they don't see why they should go to knock at their door and talk to them.
Unfortunately, it seems to me that people "breaking rules"
here (incl. the Swiss!) have a tendency to not take upon themselves their "faults" and cooperate: some neighbours from the building facing our bedroom use to have loud summer-parties on their balcony long after 12pm: if we politely ask to adjust the volume we get at best a "scho guat",
but the noise starts again after a few minutes, or even just a thumb down from them (not to mention other fingers..). So sad but true: a call to the police tends to be the most efficient solution.
My advice: be proactive when you know that you have a party/need to wash on a sunday, etc.., or just "invite" your neighbours to contact you, should you break "the Rules"
