Intake+Mic=Problem

My 2014 F Sport seems to have developed a very annoying issue. I have taken this road trip 3 times before without issue. This time I have an issue. Right off the bat, get up to about 75 mph and my wife and I go "What the heck, where is that annoying sound coming from?!" It sounded like a door wasn't sealed but I couldn't even begin to figure out where the whistle/whine/buzz was coming from. I had mentioned that it sounded like an old car I use to have that had a short in the rear speaker. This morning headed home I figured it out!!!!!! It's not a seal/wind noise issue. It happens at 2-3k rpms going 70mph+. When you accelerate hard it goes away. When you drop under 2k rpms it goes away. Keep in mind it doesn't do this at evey speed, only at 70+. Bam it hit me. It's coming from a speaker. It's the intake. Also my wife noticed when I was passing a car that my car at 5500k rpm+ sounds "staticy", (not clean and just masculine like before) it makes a weird sound but not mechanical, more like what the intake is producing into the speakers. 4 hour drive with that constant noise made me want to shoot myself.

But the intake noise is fed mechanically, through a tube at high rpm. There's no mic and no electronics associated with it. It's just a vibrating diaphragm. Were you listening to music through the aux port possibly?

Darn, that means I'm wrong. No I was listening to satellite radio, and I even tried turning it off but the noise was still there.

I also listened to Bluetooth and FM, still had the noise. Also had the sound even if I turned all music off by pushing the volume ****. I do agree satellite radio sounds tinny, although tolerable. I can't stand it in fords with the Sony sound though, absolutely the worst I have ever heard.

The one thing I like about this car is the engine sound is mechanical not fed through the speakers like other new cars. I hate fake sounds.

4 hours away!!! My Lexus dealer (largest in the U.S.) is only a few miles away from me, which I'm thankful about.
I would have guessed it might have been an alternator making the [speed specific] static sound in the speaker(s) while driving, but a bad alternator would not have drained the battery down overnight with the car shut-down (Off).
Edit: I assume you are aware of the bad batch of batteries. Could a bad cell (shorting out one or more other cells) be a possibility?
