I think they have to be quieter than the loud ones.
Matthew 6
5 “When you pray, do not be like the hypocrites! They love to stand up and pray in the houses of worship and on the street corners, so that everyone will see them. I assure you, they have already been paid in full.
6 But when you pray, go to your room, close the door, and pray to your Father, who is unseen. And your Father, who sees what you do in private, will reward you.
