It's only discussed in a similarly ambiguous way - like that they know noise is a potential problem that they're working on. Though to be fair, the designers probably have no idea themselves, since apparently nobody has built a prototype engine that could be run at the rated thrust level in a way they could check the real-world noise and vibration on.

I would assume that these days you can simulate that increasingly accurately before you need a full-scale prototype.

They could also use active noise cancellation, which is already used in some turboprops like the Q400.
