Legal proceedings were brought against the farm near Munich by a couple who moved in next door in 2011 and said the cowbells were too loud and disrupted their sleep.

Five years into the case, Judge Johannes Nagorsen finally suggested that he and his colleagues spend a night next to the dairy farm to judge how loud the cowbells are.

The judge used a phone app to confirm that the noise was just 60 decibels, barely more than conversation, The Times reports.

The husband and wife who complained about the noise have now exhausted all of their legal options.
