I've shot shield and parabolic and I know for a fact parabolic is quieter. I can't comment on banana cut.
BTW, even with parabolic, if the feathers get worn (pieces missing) or ratty looking (ends getting frayed), the arrow will make a "hissing" sound in flight.
When I hear this sound, I re-fletch.
I agree with the above.
I'm pretty sure what makes difference is the taller "unsupported" barbs.
A moon cut is really quiet.
The tallest barbs are supported well since they are in the middle.
A trad cut or Pope and Young cut with the longest barbs hanging out the back make quite a bit of noise.
Smaller ( read less high )feathers of the same shape are quieter.
I've sorta settled on 4-4.25" T-hawk chopped with little choppers.
They have pretty good support for the longer barbs thanks to the "swoop" in the back.
Also, they have the longer barbs towards the back.
It might not make a lick of difference, but I figure the tall barbs are doing most of the work so might as well put towards the back where they have more leverage to do their job.
I went with the 4-4.25" because they had more surface area than 3-5", and they were quieter since they were smaller.
...and I like the looks of em..
My 2¢. YMMV
