CPAP Machine Noise

unlike older machines (not sure about the M) there's no switching in the s9, it just varies the turbine speeds as needed

Hrd to tell - if it's motor noise I can't help, but if it's air movement noise, try getting a Passover humidifier, which is a flattish tray with baffles in it, that muffles the airflow noise. I don't put any water in it, just one hose at each end and it quiets right down

Bill L,

I just wanted to add some more information to what has already been said. I just "upgraded" to the same model you have after 7 years of a Respironics M Series Heated Humidifier. My new as of Nov. 2014, Respironics REMstar Pro C-Flex+ System One Heated Humidifier is very quiet compared to my old model...hands down!! The only noises I have is from my mask. I use the ResMed
Swift FX for Her and sometimes one of the pillows get shifted while I sleep and my husband says I "jet blast" him. I've just had to play with the position of the nasal pillows and then I'm good.
Hope you have as much success as I've had using a CPAP machine. Hang in there. I also put mine inside a serving tray so that if it were to develop a leak it wouldn't damage my wooded table it sits on. I do like the idea of placing in on a mouse pad inside the tray( in my application). I think I will do that as well.

Try it with a cardboard box, maybe cover the box with a blanket or a piece of carpet as an experiment. (Not when attached to a patient, obviously, draft one of your employees for a sound test.)

No, In a sleep lab you should have equipment that works properly and within the specs of the machine. What an impression you will make to patients coming up with some makeshift box to keep the noise down when a properly working machine shouldn't be making that noise in the first place.

For the sleep lab, try the cardboard box/blanket as suggested without a patient in the room. Use another employee as a "breathing dummy." Figure out whether it helps enough with the noise. If it does, make a professional looking box/enclosure/drawer/furniture thing to keep the noise down if you want to use that solution. Buy one of the CPAP silencer boxes if you think that looks better. Or get some sort of rollaround 19 inch rack mount cabinet and stuff it in there if you want to look "industrial."

You're assuming the "noisy" machine katiecat has is "defective" somehow. Maybe it is, maybe it isn't.

A fan blowing in the room may also help to mask the noise.

Bill L. sounds like a good set of ear plugs are in order, the mask has to vent and will make some noise. (probably quite compared to snoring )
sounds like your chasing to wrong tail ....
Good Luck!
