Comes through the radio speakers, especially through the sub if you have one. Yes it is there all the time and changes with RPM as you go through gears.
If this is true I stand by my first reply. Mine does not have it.
It’s there. I got rid of my fake sound with forscsn and I have a 20 XLT FX2 also with the 302A and tech package.
It's not. I don't have the B&O and it was there. People who think it's not there haven't actually tried to disable it.
True have not tried to disable it. Also I have no need for Forscan. Also if answers to my previous post ?'s are yes as Gizmokid stated, then I still say my truck does not have it. ? Unless some one can come up with a better explanation of how & when fake engine noise operates I still say no.
I'm with you. I've tried revving the motor setting still, running hard down the road, and all sorts. Still I don't hear it. Maybe I don't have the best hearing but my truck is pretty quiet. I've been thinking about an aftermarket exhaust just so I can hear some noise.
Forscan is free and how to do it is listed on here. Not to mention a myriad of other things you can tweak yourself. It’s really worth learning how to do it as you can pretty much tweak any Ford using it.
That's been my take. I knew it was a thing, it existed on my Mustang too. Would I have really noticed if I'd never heard about it? Almost certainly not, but that's because that's exactly how it was designed, so from a driver/passenger's perspective, it was completely seamless and you don't think about it.
ANC is not on by default ? Sucks .................
Yes, they would allow for the air in the cabin to exit using vacuum to prevent the windows from blowing out at hypersonic speeds. That which I shall obtain once I've installed the Ford Performance tune on order with Benny. 
Uh ................. If you can hear the air pass thru the rear bulkhead cabin vents, who is in the driver's seat ? And, have you stripped all the sound deadening material along with the second row seats from the cabin ?
