Imagine a punching bag hanging from the ceiling. You slowly push and pull it. It sways a bunch with your pushing and pulling. Now, instead, you push and pull quickly. It can’t move much, because you’re just not pushing long enough for it to really get moving.
Walls behave like this punching bag, and the more they move, the more sound passes through.
