What's the hollowing/whistling sound in the dash while driving on highway? on 2005 Ford Explorer

And is it expensive to have fix? I'm a woman and don't want to be taken for all of my change.

Need more info. It could be the seal around the windshield glass needs repaired or a gap in the insulation.

It sounds like it is coming through the vents and radio area
