It will be very interesting to see what impact the new roof has on the loudness of the Dome.
I haven't seen anything written or speculated about this yet. I would think that having most of the new roof becoming hard, more sound will be reflected back towards the fans and the field and it will be louder than ever. It looks like the PTFE middle section might be good at absorbing sound, but kevlar is good as well.
A semiempirical model is presented describing the acoustic behavior of Kevlar 29, a bulk absorbing material. The model is based on an approximate solution to the one-dimensional equations representing conservation of fluctuating mass, momentum and energy. By treating the material as a momentum...

The roof will be a little higher. That might hurt the loudness a little.
My guess is that the Dome will get a little louder. Any acoustic experts willing to weigh in on this?
