I was thinking since she produces the sound with her body (it emanates off her skin) that it would resonate through her bones and she'd have no way not to hear it.  But now that you bring it up, she could possibly produce a counter-wave (similar to how noise-cancelling headphones work).  Yay harmonic superposition!
