Window screen winds noise

Has anyone had an issues similar to this and if so what was the cause and the way of fixing it
if you have a sunroof, drive at 50 mph and have someone stand up through the sunroof with a length of tubing in one ear, the other end of the tubing fixed to a stick or wand so one can move around the free end of the tubing, searching for the noise origin.
Suspect cabin ventilation system? What would have to have been moved/changed to replace the windscreen?
