yes if she hits the right low frequency. Its like having a speaker on so loud you can feel the vibrations in your body, she actually controls vibrations, but thats just sound really. But she is sending vibrations into them that will squish and expand the body, with enough force and the right frequency it will build and get stronger and stronger until it makes it hard to breath and passing out comes afterwards, if she overdoes it it will kill.
another way to put it, is when bombs go off, the wave that it sends out is what kills more then the fire itself, most are dead before they hit shrapnel. thats not counting small bombs.
