When Bill was living what we did was get a long oxygen line for his machine and we put it in the dining room so we didn't have to listen to the machine.

Mine has an extra long line but it's sitting in my bedroom unused anyway. I couldn't stand the noise of it either.

I do think they have come out with quieter ones though. A friend of mine had them come and get hers and bring her a less noisier one.
