I was interested in your use of a muffler. I would have thought the system was calibrated for a particular hose length / diameter and mask type, and adding extra volume in the air path would affect the machine's ability to maintain the correct pressure/flow rate and measure apneas. Did you experience any problems in this regard?
I bought a pocket CPAP manometer and verified that the pressure is the same with and without my little muffler. I did the same test for both the Transcend and my Respironics System One CPAP machines.
It sounds like everything's covered and you've overcome the noise problem. Excellent outcome.
