Well, if she knows that a group of people is talking about sensitive information that she wants, but she cant quite hear it, she can increase the pitch so it carries across to her hiding place without alerting them of her presence.

Or in a loud stadium full of panicking people, she can create a loud noise to gain their attention.

Or in a solitary combat setting, she can go all out and rattle people's bones or deafen them, make them nauseous and disorientated.

And I'd say no, since the fact that it is generated from your characters aura would interfere with my characters aura. If anything, it might drop the pitch down maybe one or two notches but it wouldn't cancel it out, or (if they are on the same side) it may raise it by one or two notches, but it wouldn't make it too much more powerful.
