Putting down a sound deadening mat will not reduce the transfer of bass to downstairs.
Assuming it was an issue, does it help to prevent transfer through rafters etc on the same floor? I think its called Flanking noise?

The mat that I came across was Tecsound floor 100. If it doesn't help reduce sound transfer, what's it for? Does it just damping the sound in the room?

Your wife will hear you. You could set your music running upstairs and go downstairs to measure how many dB are audible, especially lower frequencies.

Isolation is going to be the tough one. Once that is done (ie. planned in detail) you can plan the acoustic treatment in the room which will be relatively easy.
Yes, I'm going to try some measurements and see which room is currently better isolated and what the transfer rate seems to be.

And yes, you are right, usually a larger room is preferable to a smaller room. As we have no specific details a specific answer is not possible.
I provided room measurements, what other details would be useful?
