Unless I did the math wrong; the maximum filling fraction you can get
with these rods is about .8. So I think there would be a problem there.

I'll have to do the math, but I think it can be quite a bit more with a hexagonal packing.

The math was to much for me, so I turned to Wikipedia. The maximum filling fraction of close packed circles is about 0.9069. Close enough to 0.907. 8*)
I would say that even though it would provide the best signal attenuation, I don't think a 0.907 filling fraction would provide a very useful muffler.
