I would have to agree that I don't like it when people talk on their cell phones at inappropriate times (during flights, in theatres, etc.) and, yes, it is usually because they are usually way too loud.
I wouldn't say that their conversation is worthless banter, though. The content of the conversations is probably important to them.
