Hi Mike,
Yes, an oblate spheroid shape intuitively makes sense to me.
While testing my newest windscreen design this spring, I may have discovered
that UFO shaped windscreens may inadvertently act as decoys attracting actual
miniature UFOs. (of course I think I am just kidding... maybe)
Just take a listen what I recorded this spring out on remote public lands in
Central Oregon the middle of the night. I believe this is anthronoise from an
aerial drone - not natural sound.
