Interesting thought, Steve.
Here (Hear?) I thought the reduction in noise was going with smaller feathers that Doc Ed said might need the turbulator!?
BTW, will a shed do? My friend and I took turns standing behind his shed and shot past… both of us have some hearing loss with age, but we could tell the difference between 5″ low shield and the 3″ A&A fletch.
To keep it honest, we mixed up the order of shooting each and the shed hider had to call out louder or quieter as each went past…
We both were 100% on hearing the 3″ were quieter.
Lots of fun stuff in all this SIMPLE stick and string!
