I've seen Harriers at airshows several times. Man, they're loud and not in a good way (like a good old radial engine). I'm talking about ear-splitting bone jarring loud. I can't be sure how long they hovered - you tend to lose track of time when your fillings are vibrating. It's possible they hovered less than 2 minutes but it sure seemed longer.

My last time to see a Harrier do its act was at Oshkosk 96. I was a vendor there and my booth was within 100 yards or so from the flight line. I hated it every time the Harrier did his act (several times that week) because it drove away customers. Man, if I could've gotten my hands on a Stinger, I would've ended that problem. About the only louder plane I heard that week was when a B-1B went full afterburner for takeoff. It was so loud, I though I was going to get sick even with my fingers stuffed up my ears halfway to my wrists.
