Resmed Airmini Muffler

Has anyone fitted two Q-Lite mufflers in line-instead of one-will it make it make a difference and why will Resmed not make one.

I found that running a white noise beside the machine virtually eliminates any noise from the machine or breathing noise in the mask/hose. I downloaded a free white-noise app to an unused cellphone.

The brown-noise option works best for me. Don't omit the 'i'.
