Ventilation system 2011 Mustang V6 Premium

I have an annoying problem with my 2011 Mustang V6 Premium’s ventilation system. I can’t hear the good tunes because the sound of the rushing air is too loud.
I can even turn off the A/C entirely and, as I accelerate, it gets louder and louder. Is it that some vent door is not closing? It gets really annoying! Does anyone else have this problem? Is there a remedy, aside from turning up the tunes?

If the car is still under warranty, a trip back to the Ford dealer is in order.
