>So this poses another question. Would a pipe folded 8 sided (octagon) be any different in performance acoustically & wave wise? Odd and even numbers sometimes mean black or white. Obviously the more folds the better (360;-) as it would make it 'rounder', but sheet metal folders have limits too.

I don't think gases would even notice it was not round, if it were 8-sided.
Some people who make their own wooden spars for boats leave them 8-sided, rather than proceed to round them fully. there is no record that I know of, of such spars being weaker in any direction of stress than round spars.
Maybe pipes are that way too. Once they are 8-sided or so, might as well be round as far as gas is concerned.
Yes, I know the two examples have nothing in comon. I am using engineering license here.

PS. Hey, Bill, maybe you should build that big megaphone by bending sheet 8 times? An 8-sided truncated pyramid rather than a cone.
