I also vote for getting a different (data-capable) machine.....if you have your prescription and some extra money, they're not all that expensive if you look in the right places.......like CPAP.COM or CPAPAUCTION.COM.

What he said. I would like to offer some considerations on loudness, though. We each of us hear differently. My father, before he died was nearly deaf. So when he watched TV, he turned it up too loud for me. He had perfect hearing (for the average human) when he was my age. He was the one they tested twice because nobody got a perfect hearing score. He went deaf, I think, because he snored so loud, it would rattle the windows in all the rooms of the house - literally. My Mom went deaf in one ear because of it, too. I don't know how she put up with it.
The public school I went to as a kid had hearing and vision testing once a year right at the school. The school nurse usually left the door open to the sound booth so the kid inside wouldn't get scared. I touched each ear when I heard a noise, as directed. A few times I didn't because the pitch was so high, it sounded like the normal squeaks and twitters I heard all day long anyway. So as I left the booth, I asked her - what about all those high pitched noises - was I supposed to recognize them? I told her sometimes it was hard to know whether it was a noise I was hearing from outside or a noise I was hearing from the headphones. She said - 'Let's try that again' and this time closed the door. It was the first time I can remember experiencing total silence. Cool! It was easy then to distinguish the sounds she was testing. I also noticed that the sounds she was testing for also sounded considerably louder since there was nothing else to screen out.
What sounds loud to some people is barely audible to others. Coupled with ambient noise levels, what sounds loud at one ambient noise level can sound almost painful at a much lower ambient noise level. Another consideration is awareness. If you are entirely engaged in something mentally absorbing, you're not as likely to notice an obnoxious noise level as when your mind is not otherwise engaged. Similarly when you are unconscious. It's like that tapping noise of a dripping faucet late at night. It's not loud. It's just damned annoying because now that you're aware of it, you can't stop thinking about - Like the Gilligan's Island or Spongebob Squarepants song you can't get out of your head. So Environment, physical ability and mental awareness combine to produce a perceived level of loudness or softness of sound.
It's why our children are going deaf from listening to their iPods. The perceived loudness seems fine when you're out on a crowded street, but the prolonged exposure at such levels causes hearing damage. It would be interesting to find out if there are any studies about perceived loudness and whether or not merely-annoying-but-not-necessarily-damage-level noises can damage hearing.
