Can the sound of the grandfather clocks be turned off anytime?
Yes, most grandfather clocks have a silence lever on the clock. Moving the lever to the silent position will allow the clock to keep time, but there will be no sound. When the clock is silent, the two outside weights will not drop, only the middle weight will drop. Most grandfather clocks also have a night shut-off lever; this allows the clock to be silent from 11:00pm till 6:45am.
