Not sure but maybe this helps. I made this a long time ago mainly to make a smaller umbrella that wouldn't make my stand too top heavy. I just cut one maybe 2 rib sections (can't remember), cut the excess fabric, and glued the stretched fabric underneath with contact cement. It makes for a fairly flat umbrella. I secure it to the stand with 2 hose clamps.

Thanks. I've see that photo and it doesn't address the reflections under the umbrella that make it sound like I've stuck my head into a very large mixing bowl. It's not rain noise I'm inquiring about but how the taut fabric of the umbrella effectively reflects sound down toward the microphones. It least with the Drizzlestick, the coloration is very audible.

Yes it does - there is acoustic foam under the umbrella to do exactly what you asked for.
