I made my last cage which was 6ft 10x3ftx2ft out of 1x1wood (which I polyvarnished 5 times) and plastic coated mesh, Foufou has it now. The cage I use now is a big viv I made with wilow trellis on the walls and mesh on the ceiling, branches etc. Pics are on here

No they are not very noisy, they may bark now and then in the night but I live in a flat and dont feel its loud enough to disturb any of my neighbours. I dont hear the wheel at all now they are in a viv but could hear it before but I am a very light sleeper.
Look on the vet link here
