The wooden mallet that a judge uses in court is called a gavel.
Judges have them as a symbol of authority and also a forceful signal - they hit the sound block with the gavel to signal that the court is in session. They also hit it when the court is adjourned, when a sentence is passed and to demand order and silence in the courtroom.
The gavel has been used to control meetings since the middle ages and there are rules for its use in 'Robert's Rules of Order'.
