Depending on which order you joined, there would certainly be quiet. There were teaching orders like the Benedictines, with their light brown habits who also had infirmaries (hospitals), there were Dominicans in black habits who drove the Inquisition forward. There wouldn't have been much peace with them around until they were at their devotions. They used flails to chastise themselves for wicked thoughts. Then there were the Franciscans in their characteristic brown habits who spent a lot of time in splendid isolation. There were the Knights Hospitallers around the time of the Crusades who tended the wounded - and created more dead and wounded when they set about the Saracens (Turks). There are modern orders in Britain, some of which are non-speaking and others who teach or tend to the sick. Most orders were summoned to their devotions four times daily. Some spent all their own time in seclusion and only ate together, like the Carthusians. You'd have to be pretty dedicated to join any ot them.
