Help with noise on my M Series

th · Post by th » Sat Jul 05, 2008 5:41 am

The noise on the M Series( REMStar Auto with A Flex) is still giving me trouble. I have cut a hole in the back of my nightstand for the hose to come through. If I close the door to my nightstand, I think I can deal with the noise. I know air ( no Air) and heat can affect the life of a CPAP. If I do not add any insulation on the inside or put anything in the nightstand will this create any problems ? Can this be harmful to my CPAP? Can I put a solid piece of insulation on the back of the nightstand which would reduce the noise more (back of nightstand made out of thin plywood) or would you leave it alone?

Thanks

What noise is it making? I have that machine and it does not make loud noise. Maybe something is wrong with yours.

There is nothing wrong with the machine. I was use to the old battle tank (RemStar APAP C-Flex) which is a very quiet machine. The M Series has that very low whining in & out noise. I am very sensitive to ANY noise. I though after 60 days I could have gotten use to it but I have not. I would post some pictures of the nightstand with the cut out but I did not know how

th

I wanted to add: I did not hear the machine at all last night(with this setup) an excellent night

I'm glad yours does not. Some M Series are quieter than others. I can tell you Apria will not exchange this unit until I can find (quieter) one that I like.

Thanks for the help. I still need to know if :putting my APAP in my nightstand and by cutting a hole out the back of the nightstand will this be harmful to my APAP?

NOTE:
This is a large nightstand and I do not keep anything else in it except the APAP.

mine has done that a few times. only when that sucker gets cranked up to a high end pressure, or leak. haven't noticed in a good while now & it sits within reach not covered up.

Guest(s), that's great that your M machine is quiet...whether the machine itself is pretty quiet or it seems so to your hearing.

It's not unusual for any one "cpap" machine to sound different from the exact same model that someone else is using. People on the message board have reported very different sound experiences with same model machines as others use.

Sometimes it's a matter of higher pressure settings producing more noise, or whether an exhalation relief feature is being used, or.... just plain "luck of the draw" -- what sound that particular machine made when it came off the manufacturing line.

th, here's one of the pictures you sent me of your machine in your nightstand:

I'm no expert, but the hole you cut in the back to run the hose through looks like plenty of air can come into the large area the machine is set into. If it were me, I'd go ahead and do whatever extra soundproofing you want to try on the back of the nightstand.

I'd probably set the power brick outside -- to have one less thing that might get warm. It's normal for the top of the machine itself to feel warm after it's been running for awhile.

I'd use the machine one whole night with the nightstand doors closed and a thermometer placed inside. In the morning, you could check to see if the temperature was staying ok inside that area.

The Provider manual for the M Auto with A-flex says this about temperature:

I'd also put the machine iteslf on a towel, or a mousepad, or both.

Not an expert, but I suspect that enclosing it in a big empty HARD space will cause the sound to echo and amplify.

Definitely contemplate a mouse pad.

It took me a while to really get used to the noise it makes, but now it doesn't bother me at all. I shared a hotel room with someone who had never been exposed to CPAP at all and she said it didn't bother her at all.

Good luck!!!

Rested Gal thanks for the advice and for posting the pic also. You and Ozij are still "the best" on this forum. If it was going to be a problem, I was going to buy a small cheap fan & put it behind of the nightstand and cut another small hole in the back to let more air in. I wish, I would have done this 60 days ago,not only is the APAP very quiet but I now have the top of nightstand clear of a cpap........... I still use your method of hanging my hose with a swivel hanging bracket and using a hair scrunchy (sp?)........Again thanks to the both of you. Without your advice on using an auto instead of a CPAP I would have given up years ago. You are life saver and a saint..........The best to both of you!

Cpap.com is now selling a "whisper cap" for M series respironics machines.

https://www.cpap.com/productpage/respir ... r-cap.html

I ordered one. As soon as it arrives, I'll try it out and let you know whether it makes much difference. I kind of doubt it'll make more than a small difference, but we'll see....

Best,
Ron

I ordered a new CPAP mask from cpap.com and it was $99.............I spent hours trying to find another item to get the free shipping............I guess I will have to wait 6 mos+ until I get to try it(order another mask)...................please PM and let me know what you think..... I travel and this might help......... when I cannot take my nightstand with me

I got one of these a week or so ago. It makes a huge difference in the sound level, at least for me. I wasn't so terribly upset with the noise before, but bought the whisper cap when I was getting something else just to see how well it worked. I'm impressed!

I'm happy to hear that, lawtalker. I wasn't sure whether I was throwing my $$$ away, but thought it'd be worth a try.

Incidentally, I know most of you have already thought of this, but just in case one or two of you haven't:

Running a fan or other constant ambient noisemaker while you sleep is great for masking noise from cpap machine, mask, and also any outside noise from traffic, neighbors, etc. You've probably seen those noise-making machines at Sharper Image that can play white noise, ocean waves, gentle rainstorms, running river sounds, etc. My wife has slept with a fan running in her bedroom forever - she used to live in a noisy apartment complex and is so used to the fan that she can't sleep w/o it, even though we live in a quiet neighborhood now.
