Noise levels of Goodknight 420G and Everest Aura

I have a 420G that I like a lot, but I the Aura looks like it would better fit my camping and traveling needs.

Has anyone had to opportunity to compare the noise levels of these machines?


My 420G is a louder than my Fisher & Paykel and has slight Darth Vaderish rise and fall in the noise level. I notice the user reviews on the Aura complain about its noise.

Bump? Anybody there?


If you can't make a comparison, how about personal experience with the Aura?

Thanks,

If you can wait til like Monday, I'll try to give you the sound pressure difference between a Remstar Classic Auto, a Remstar M Series Auto and a 420E which should be very close if not the same as your 420G.

I'm interested in seeing that difference myself.



Much of the noise we hear from these machines depends on the mask being used. A machine may be quiet, but that can be because the mask you are using is so noisy that it drowns out the noise from the machine.

Use a mask like a Soyala nasal that is silent and all of a sudden the machine becomes noisy.

Higher pressure from a leaking mask can also drive up the noise level.

I have the remstar apap and the Polaris/everest/aura. The sound seems to be about the same volume but the polaris/everest/aura is a higher pitch. I don't find it bothersome but some might.
