Enforcement in Germany is quite funny. Lived there for some years.
If you have a problem with noisy neighbours you basically must make a "noise diary" with date/time/description of the noise over a period of time before anyone will give a shit.
Even then, enforcement varies wildly. Seems to depend where you are, etc.
The best person to complain to is building management, but even then, they vary.
The next best thing to do (and the most German solution) is leaving passive aggressive notes on the buildings noticeboard.
