Strange question

The males will bark or croak. Usually this is to attract a female. Mine will bark late at night, but sometimes during the day too. Also when the dominant male is re-asserting his position, the FBT he is dominating will make a warbley sound to show their submission.

I only have males, so I can't say if the females make some sounds at times.

Yes, it all depends on how many males you have and your lighting schedule.

My males usually croak around noon, stop and start around 8 or 9 right after I turn their UVB off then sing me a song through the night, they usually croak all day if its storming outside.

Like Pivet stated before, they usually do at random times to re-assert dominance, usually the largest will do this. It sounds like a fast pased croaking mixed in with the dominant males croaking.

How loud is it? Is there anything you can compare the volume to? Can you hear it throughout the house or only in the room?

Really all depends on the placement of the tank, I can usually hear my frogs coaking from down the hallway, you can always play music near their tank and they'll stop if it gets too annoying for you.

I agree with Marinecrab. You'll know it if they are barking. If you are a light sleeper, they'll annoy you even if they are a couple rooms away in a quiet house.

Funny thing that is, some people get frogs so they can hear singing but ultimately get annoyed.

To go a little further on the OP's question..... If the FBT's have not made any vocal sounds, then they might all be female or they are still juveniles. Though I've never seen anything that says juveniles don't bark.
