I always took that particular sound effect as a sort of snarl. I think it's got to do with Bane playing with Bats during the first fight...in the moments preceding Bane's jump and turn, Batman is practically pointlessly punching him away. I always took that jump/spin as a sort of "Enough of this nonsense/****!" moment. Bane has had enough of Bats' weak attempts at fighting him and finally proceeds to truly beat the crap out of him.
