The residents complained the thin walls of their building led to them being able to hear their neighbors using the toilet while they were trying to sleep, The Local.de reported Tuesday.
The court ruled the noise was "socially acceptable" and told the residents they could not withhold a portion of their rent in an attempt to force the landlord into soundproofing the walls.
The judges said regulations about sound insulation depend on the age of the building, and the apartment in question dates from the 1950s, when insulation regulations were lax.
