Maybe the airbox got disconnected from the snorkel assembly in the fender? Follow the intake and see if it's intact. The noise you're hearing is vacuum in the intake manifold escaping through the throttle body. It's perfectly normal. Usually the airbox acts like a muffler so you don't hear it. It definitely sounds like the intake is disconnected somewhere.
