THE CPAP SOUND BAFFLE SYSTEM™

If you can't keep quiet then keep busy:

.....yea......'dude..could you let us know what you come up w/for that.

Forwarding...

I'm surprised no one else has asked this, but...

How is the heat from the machine being dissipated? It would seem that you're insulating the machine and concentrating the heat potentially causing early failure of some of the electronics. I don't believe that these machines have active cooling and the blower is enclosed so it cannot assist with that function. My machine is warm to the touch after a night of use.

Just something to think about.

The machine case is actually full of foam surrounding the motor. The circuit board is on top. As long as there is a little airspace, it's fine.

There is foam on the bottom, but nothing on the top at all.

Thanks for posting those pics, as I've never seen the inside of a machine before. Learn something new every day.

My machine doesn't produce much heat. The back is fully open all the time, so there is plenty ventilation. It also makes it easy to remove and replace the data card. Plus the whole thing can just lift off without trouble from the hose or wires. In the morning, after just waking up, I've placed my hand in there and I don't have any heat issue with it.

So it's been working very well for me. Let's just hope I don't have to build one for my PR System One machine (on the way). Because I can't think of a what a design ordeal that will be, with the hose on the humidifier coming out of the top. I am hoping the new one will be much quieter and I won't have to make a sound baffle.

Don't forget the smoke detector.

not to worry.... Respironics is getting rid of the M series any way..

Not to worry about the noise.... Respironics is getting rid of the M series. Should have gotten a ResMed
