Would it be of any use to put a GIK 244 panel on the ceiling above where the projector pole is coming down? I would even consider cutting a hole in the middle of the panel for the pole to come through, if this is useful at all. Just wondering if that would cut down on any of the perceived noise since the noise reflected off the closest surface (the ceiling) would be lessened.

Just an idea I had... based off nothing .

Useful or useless?

I would guess useless, since there would still be noise coming from the sides and bottom of the projector.

Yeah I know about the hush box.. I was just wondering if this would be something that would give me a small bit of noise reduction. Sounds like thats a NO.

I doubt you would be able to notice even the slightest difference after putting in the effort. You’re beneath the projector and there’s nothing between it and you to impede that noise, so an enclosure is your best bet.

If you go the route of an enclosure and still find the noise to be bothersome, you could line the inside of the box with some thin foam to add some dampening, perhaps something like a closed-cell neoprene. And of course, the enclosure would have to be sized and ventilated properly to keep the projector from overheating.

I'm guessing he has a spare absorption panel and is trying to find a use for it.
