[CPAP] "Wheezing" sound from mask
#11
I see two possibilities here.  One is that when you first started you were so distracted by and concentrating on the hose and the mask and the air and the strangeness of it all that this noised faded into the background. It was the least of your worries. Now that you are more comfortable with the therapy, you are starting to hear this noise.  The other possibility is that you have a defective unit and the blower is making more noise than it should.  My first DreamStation went bad like this and I returned it for a replacement.  

How loud is it?  Louder that a room fan?  If so, I'd take it back to your supplier and let them listen to it while you have the mask on.  They should be able to determine if something is wrong.  It coudl also be somethign like a silicone gasket that is out of place.

If it is not that loud, it is likely normal.  These machine are quiet but not silent.  They maintain a pressure by supplying a varying volume of air by changing the blower (fan) speed.  When you breathe in, it needs to supply more air and it does this by spinning the fan faster.  When you exhale it needs to supply a lower volume of air and so the fan spins slower.  Hearing the cycle of rising and falling fan speed is normal.  I can see how this might be described as a wheezing or groaning or Darth Vader noises.  Changing your pressure will not change this.  Using a hose cover might reduce it depending on whether you are hear it from the machine itself, or from the air flow in the hose.  Keeping the machine in a bedside night table will also help.  Just make sure to allow for enough air flow into the machine.
