I'll be interested in the answers. I hired a big industrial sander to do our front room, kitchen and hall floorboards, but I was just thinking today that they're all looking a bit scruffy and could do with being re-sanded. I'm not going to hire a sander again as I remember it being a nerve-wracking job, with the belt flying off accompanied by loud bangs and sparks flying every time it hit a nail.
I've a feeling that the only solution for me will be to get someone in to do it. That won't solve your noise problem though.
