How much noise is usual in a Resmed S9? - Benzi - 12-02-2020
(Apologies to anyone who saw my posts on this in a couple of other threads: I'm getting desperate)
If you have (or had) an S9, can you please share your experience regarding the amount of noise it makes?
I've been using the machine for a year. After failing to get used to CPAP on 2 previous occasions (the last was 8 years ago), this time I persevered and succeeded. One of the reasons for success: the machine was much quieter than the old ones that I used, which used to keep my wife awake with their noise. My wife said she couldn't even hear when the new S9 was working.
A couple of months ago I added the humidifier and changed my mask to a p30i.
All was fine till a couple of weeks ago when my wife said that noise from the machine was waking her up. (In addition to waking her up when the mask shifts and the whooshing sound comes out of it.) I started paying notice to the amount of noise from the machine (I never bothered before because in any case I get some noise from the mask), and indeed I can hear the fan when I inhale or exhale. The stronger the inhale/exhale, the more sound from the fan. Not a whine. Just like a ventilator.
I took the machine in to the distributor's lab -- they said the machine was fine, that you hear the sound of the fans from all machines, that the S9 is the most quiet machine that they know, that I should try using it without the humidifier and see whether that makes a difference!
So now I don't know whether the machine has started making more noise than it used to - or whether we have become more sensitive to the noise. (Maybe this is another side effect from being under COVID-19 stress for 9 months....)
Can you please tell me what level of noise to expect?
Thanks!!!!

I didn't see where you stated whether you tested it without the humidifier. It could be a bad humidifier seal. I'm a bit surprised, S9's have been out of manufacture for about 6-years (2014). Most should be hitting their run-hour limit. What is your machine's time?

Keep it low so bed will take most of the noise and if possible in a drawer of your dresser. My wife is a light sleeper also and I found a way to keep the peace so to speak. Less chance of rainout also if the machine is lower IMO.

I use a side table with drawers, and keep the machine inside with the tube and power fed through a 2-inch diameter hole in the back. The drawer is shut at night and no sound. Zero, zip nada. If you have the space for a bedside table, you can just upgrade to one with drawers.

Someone who deals in CPAP equipment looked at the label and said the machine was manufactured in 2019. Could be Resmed is selling it in specific countries. Or someone bought a large stock of them. Whatever. In any case, my insurance pays part of the price once in 5 years so I'll be using it for the foreseeable future.
When you talk about "run-hour limit", what are you referring to, and where would I see it?
Regarding the humidifier: I tried without it, didn't seem to make a noticeable difference.

Sounds like a great idea. I'll try putting it in the drawer - after I've removed all the stuff that I haven't used for years

Update: the s9 spent the night in the drawer. My wife couldn't hear it. Problem solved.
Thanks all for saving my marriage ! ?
Now I need to find someone to make a nice hole in the side of the table.

I just used a 2-inch hole saw and drilled through the back. I will warn you that putting the hole through the side may prevent the drawer from sliding when the tube and power are routed through. By putting the hole in the back of the cabinet (and in the drawer itself if needed), the tubing will slide with the drawer and remain completely concealed during the day. Here is my setup. Note the tube runs to the rear at the top of the drawer. My tube is attached by a lanyard to the headboard to keep it from dragging on my face.

Oh my - thanks for saving me from ruining the cabinet by drilling a whole in the side!

And after looking at your setup, I now understand that I hear noise from the air blowing through the frame of the p30i mask on the sides of my face. I imagine that your mask (which one is it?) is even quieter than mine.... I might consider trying it but after all the time that it took me to get used to the one that I have,...
