I've been trying to come to a conclusion for a while now, and at this point I figure its a up to how her ability works. One idea is that she feels the vibrations and they are somehow filling in an mental map, in which case more vibrations are actually a good thing. On the other side, if she is sensing the vibrations coming directly from movement then being surrounded by vibrations would make it useless. Since It could go either way, I'm leaving it up to you to decide which way it goes.
I don't know when this will be incorporated into the story, physical bending is higher on his list.
