Re. Germany, it's not quite like that, but there are some restrictions in places, mostly on circuit bashing. These are all detailed in German flight guide, or Bottlang Airfield manual Germany 6-6 "Ordenance for Noise Abatement at Airfield", or under individual aerodrome entries. Land-away flights are usually OK but you may have to show a noise certificate (the CAA issued one FOC for our C150).
