It could be kind of like the odhaviing shout, it calls out to you, it shakes the entire world until it reaches you, when they call it out in high hrothgar it doesn't have to reach far, but when you're in whiterun it has to travel all the way down the mountain to reach you, so it shakes the world more violently.
