I know that none of us are the same, and what works for one person may not work for another.
Some of us, at one point or another, tend to wake up in a panic thinking our dream machine is not working! I myself am using a bi-level machine that is 5-7yrs old, and you can hear it cycle up and down as the airflow changes - but for me, whether while trying to fall asleep, or when waking in the night, I find the 'noise' to be reassuring myself. Sorta like 'counting sheep', or the like I guess.

For what it's worth I've had two Resmeds and one Respironics on loan recently. The first Resmed (S9 Autoset) and Respironics (BiPap ASV) were effectively silent - I couldn't hear them running.
The second ResMed - the one I actually paid - for was very slightly noisy to start with and over a couple of months has become progressively more so. I'm going to take it in for the 6 month service and see if they can't silence it for me.
