Sound at specific speeds

[bd3500]

I noticed on my drive home last night that at specific speeds (like 53mph and 60mph) whether accelerating or decelerating I hear this whining/whooshing sound.

It doesn't matter what the RPMS are, but I still hear the sound.

The X is an 02 3.0i sport. Doesn't matter if car is driving straight or I am in a turn.

Its almost like a low whining sound that only happens at the above specific speeds.

Anyone experienced this before? I really hope its not transmission. Car shifts fine.

is it coming from the front of the vehicle or under/rear?

what happens if you put it in neutral while rolling?

any noise when stopped, and then rev the engine?
