Droning, whirring sound audible from inside cabin, especially from passenger side.

2014 Infiniti QX60 3.4L V6 AWD, 175K miles

This started last week. It happens when accelerating above 45 mph. It is not the engine noise like the revving of the engine because when I mash on it or you know accelerate quickly, I hear the engine revving up. This is a different sound.

This is not a high-pitched sound it is sounds like a jet engine winding down like when you land in an airplane.

when you decelerate the sound/whirring decreases and becomes in Audible below 45

There is no shaking or vibration that feels unusual, I tried a recording but it’s a little hard to make out with the road noise. This sound doesn’t come from the vent specifically, but it was a place where I could hear the sound better.

I went to the oil stop where I get my fluids changed and they confirmed everything is full and normal .

Any ideas?
