I do not believe that they should disturb anyone in another room. For the most part the noise comes from play and moving about the cage, sometimes barking and fussing. With a quality, sturdy cage, a decent glider-wheel it shouldn't be that bad for the most part.
I personally have my gliders in my room and am rarely disturbed by them. When I'm awake, I actually enjoy hearing them out. Occasional arguments and barking are less bothersome to me now that I'm divorced and do not have to worry about XH being disturbed.
I had origianally had my girls in a room next to my bedroom and could barely hear them, and not at all disturbing my slumber. Also, I've had my gliders in my room being next to other's bedrooms (recent & current living arrangements) and there have not been any complaints on their noise. Their cage is and has always been located at adjoining walls to the other rooms as well, so you could take extra precautions and place them on a wall not adjoining an occupants room.
