resonant frequency ?
(OP)
The resonant frequency of helmoltz resonator, f = c/2*3.14 (A/VL)^.5 Where A is surface area & V is the cavity volme & L is the effective length.
My question is does it make a difference for Transmission loss/tuning of the system if use circular, or any other cross section like square with circular end for the connecting pipe of helmoltz by keeping same surface area?
As per above formula I don't see it but appreciate if someone have different experience.

RE: resonant frequency ?
But it will still work, just at adifferent frequency.
Square vs circular probably would make no difference that is measurable.

Just assume that testing will be required to validate the design before you go into production!
