Air sound from passenger side while accelerating
 

On my 2002 tribute, only while accelerating we hear what sounds like air blowing. This is coming from front passenger side. Any ideas?

Maybe a tiny bit more describing said air noise? Like a window cracked? Do you have a sunroof? In a far stretch a wheel bearing going south could have a woosh sound, and old Tributes had a TSB on wrong bearings installed that required replacing (mine did after only 5 years).
Why not have someone drive while you pinpoint the source closer?
