That sounds great! I would say, though, that windows and doors also can make or break noise reduction inside a home. I believe my own building I live in has either cinder block or concrete walls of some kind, but sadly I still hear quite a high level of traffic noise from the street outside because the seals of my windows are not the best. The window panes themselves are double glazed, which normally helps, but the rubber seal system around the closing parts let in noise!
So, make sure windows and doors are also chosen with noise sealing in mind, especially if there is a roadway that gets busy. I'm living in quite a bit of woe!
Personally, regarding flooring, I don't like hardwood floors, although I know they are very popular and I'm in the minority on disliking them. I just find carpeting softer on the feet, more comforting both the feel underfoot even when in shoes or socks, and also just to look at, and reduces noise by cutting down on the echo effect of a room. Carpet damps echo and voices sound softer and less harsh in a carpeted room. This is JUST me though, I know a deluge of people hate carpet and are for hardwood floors.
