Exclamation do I have a vacuum leak? help please

My 15 ecoboost is making a pronounced vacuum sound when idling cold and during acceleration. No check engine lights, nothing seems loose that I can tell. the vacuum noise I refer to is like a humming, the same humming you would hear from a vacuum cleaner,it mostly sounds like that at cold idle. I don't think i notice any power loss. what could it be? any experience with this noise. The car has a cold air intake FYI.

Not sure to be honest. I know my wife's Ecoboost makes a heck of a vacuum sound when I first start it up for the day. It has a JLT CAI installed and for the first 20-30 seconds after you cold start the car it sounds like it could suck up a tree! The sound goes away for the most part after 20-30 seconds though.

I have to be honest here man... I don't hear anything out of the ordinary in your videos. Your car sounds just like mine from the inside.
