What are the banging things used in court?

In court, the "banging" refers to the use of a gavel by the judge. The gavel is typically used to call the court to order, signal the start or end of proceedings, and maintain decorum in the courtroom. It serves as a symbol of authority and order during legal proceedings. Additionally, bailiffs may also use their voices or other means to maintain order, but the gavel is the most iconic tool associated with this function.
