Hiya,
there's no comparison between timber and concrete.
From financial point, timber is much cheaper, but if you want quality and have the money, then go for concrete.
You can erect a timber frame house in a maximum of two weeks. Wood is a better heat insulator than concrete, therefore energy-efficient. But when it comes to sound....
However, concrete is the most proven building material on earth, it's certainly stronger and more durable than wood. If your home is constructed with concrete walls, you are protected from the structural damage, say fire for example. Yes, after a few years or even months timber frame houses make noise, there's rot, rust, termites etc...Today's best residential buildings in the world are made of concrete. I do not know why timber frame is so popular in Ireland today, look at the rest of the world: Italy, Germany, Austria etc...all concrete.
And after all, when it comes to soundproof; no matter what and how much material you put with the timber, it's never going to be as good as concrete.
