My wife used a C-PAP machine for years. It bothered me when I slept also, mostly the air from the mask. The solution was, another sleep study, was that she could do just as well using this night-guard kind of device made by a dentist who was referred by the sleep clinic. I'm sorry, I forget the name of the device, but what it does, it that it causes the patient to sleep with their jaw forward. This somehow (I'm not a doctor) allows air to come in so she didn't snore. She has been using it now for about a year, and she NEVER snores now. I highly recommend talking to a sleep clinic about this device and with your family doctor and dentist. Although not all dentists know about them, but the ones that specialize in making them have test equipment, etc. I hope this solves the problem for you 100% as it did for us!
Meanwhile, if you most sleep with someone using a C-PAP machine, another thing I did was move the HEPA air filter closer to my side of the bed, and the sound it made masked a lot of the noise from the C-PAP and mask sometimes. It wasn't perfect, but that was one way I did my best to cope with it. If possible, ask about the device to place in the patient's mouth while sleeping (they are custom made by the dentist) and the results were great. Sorry I can't remember the name of the device. If someone e-mails me at eastcoastguyz@hotmail.com to remind me, I will find the exact name and see if there are links for it.
