Thanks for replying

I will add your comments to my growing list of things to try and verify.

Thanks for this great reply

I have thought of the wiring possibility and only tried moving the machine to a different room.  It only reduced the volume of the noise.  The apartment building I am in, is only 7 years old. 

You mentioned aluminum hats.  I thought of trying to wrap the machine in aluminum foil. Not sure if the aluminum will act as an antenna or wave insulator.

My focus now is on the tubing.  I can feel vibrations and and a pulsing feeling when I hold the tubing in my hand.  I am going to try several types of tubing covers.  Just read a thread that suggest I try different tubing diameter sizes. 

Lots of things to try.

Thank you and all that have posted replies.

Update on sound waves/ audio waves traveling thru CPAP tubing:

Thank you again for all the comments and suggestions.  I have not yet solved the problem.  I have tried using a latex tube and it reduced the sound a bit.  If I hold the latex tube in my hand, I can feel the pulsing of the sound.  If I squeeze the tube in my hand it greatly reduced the sound.  I have tried to squeeze the tube with clamps, tape, rubber, twisting and aluminum wraps but to no success.  I turned off the modem, took the modem out and turned off the wifi and still no success.  I have purchased and inline air noise filter and that didn't work.  I have inserted aluminum foil inside of several different tubes and no success.  I have inserted fine copper mesh inside the tube and that seems to work but this interferes with the air flow and air pressure. I have tried two machines if the same brand and model and that didn't work so I guess the next step is to try another brand and model CPAP machine.
