What is the sound

This sound starts at around fifty five sixty miles per hour. Whether the fan or AC is on or not. Does anyone recognize it?

Take it for a spin to make the noise. Then loosen belt and see if Idler pulley has play in it. May only be loose after it gets hot. While belt is loose, wiggle all the pulleys

Could be any pulley... hard to figure those sort of noises out.

My wife had a Audi TT that had a sound something like that. It turned out the windshield adhesive was giving out at the top. It sounded like bees were in the defroster vents but only while driving. Try driving with one of the other windows slightly cracked and see if it goes away. I eventually tracked it down by putting blue painter's tape around the outside of the windshield.
