Sound Waves and Balloons?

Why bother with a post grad? Are they even worth it? Have your say! 26-10-2016

    A homework question I'm struggling with as we've done nothing on it in class so I don't know how we're expected to know it...

    Any help would be greatly appreciated!

    As a loud, low-frequency sound wave travels past a small balloon, the balloon's size is affected. Explain. (The effect is too small to be observed under ordinary circumstances).

    You can feel a balloon vibrating to the bass notes in music.

    sound is a longitudinal (or pressure) wave, the balloon is a sealed elastic container of pressurised air... what do you think happens when the air pressure outside the balloon changes?
