Also, if the tank is basically completely sealed except for the small gaps for cords (if needed), how audible is it through the glass really?

Not loud at all, however, I recommend ventilation... Your frogs will benefit from good ventilation.

A good friend of mine is a glass contractor. My plan was to have a fan in one of the top corners and a couple of vent openings (with insect netting) at both ends of the aquarium and maybe even on the back. I also do not want to open it up too much otherwise it's too hard to keep the humidity.
