Independent study resource, not a BAMF website. Translations are study aids; the exam is in German.
Quick explanation
Night-time quiet hours in Germany usually begin at 10 pm.
Why is this correct?
From 10 pm to 6 am, you should avoid noise so as not to disturb the neighbours.
Background
Quiet hours are regulated in the states’ noise and pollution control laws and usually also in the house rules. During this time you should, for example, not play loud music, not drill and keep parties quiet. Many house rules also set quiet times on Sundays and public holidays, sometimes also at midday. Anyone who disturbs the night-time quiet risks trouble with the neighbours and, if repeated, a fine.
Why are the other answers wrong?
Quiet hours do not depend on sunset or on when the neighbours go to bed. And they do not begin at midnight, but already at 10 pm.
Memory tip
Quiet from 10 pm to 6 am.
