Strange, subtle noise

I have a 2006 Eddie Bauer with the 4.0. When I get to about 40 mph I hear a noise that sounds like it's coming from the center console area. It's not loud. My best impression of it would be to put a paperclip in a glass and shake it around.

It seems to be speed related and it doesn't do it all the time. It's driving me nuts because I can't tell if it's inside or outside the vehicle. Anyone else experience this noise? Thanks!

The quieter the noise the cheaper the fix, just get a female to ride in it they hear everything, youll be good to go.

Lol, right now I'm utilizing my Black Sabbath weird noise cancel knob. The female method sounds better!
