Not sure if this is even close but I had air noises (no ecoboost). I was searching everywhere for that noise but no luck. What solved the noise for me was running the A/C fan on second speed to build cabin pressure. This kept the air leakage going out instead of in and stop inside noise.
After looking closer at rubber gaskets and seals that would allow airflow I notice how gaskets around door were shorter than they could be to completely seal edges. The outside side window gaskets that should be touching glass have about a sixteenth of an inch gap that not only allows air flow but also water to fill doors and damage actuator mechanisms. A combination of these design issues, in my mind, allowed air flow that created noise. The build up of internal pressure caused noise to flow out with the air, maybe. But for whatever reason I have a quieter ride now.
