Hi To All
I have been using a cpap for about 14 years or so, I just received a new Sandman Auto by UPS today. And I have a question that I sure could use some help with.

My pressure is set at 11cm Min. and 20cm Max.

My question is this, when I inhale the cpap makes a high pitch sound, and when I exhale it makes a lower pitch sound, also I notice when I exhale that there is a low sounding rumble that I hear and can feel all the way thou the hose and mask. is this normal , for the Sandman Auto cpap?

I just wondered if this is normal before I send it back.

Thanks
