It's a bit late for this maybe, but depending on your (and her) personality, over-the-top "anger", with a grin, works.
Like "AAGH! I'm going nuts in here! Will you STOP that? If you don't stop that popping soon, I swear I'm going to STRANGLE you!!"
But this only works if you're on top of it and can laugh at it, in a sincere way.
This is what my next-door office mate does when I play music he doesn't like or talk too loudly on the phone![]()
