Acoustic impedance of material is defined by density multiply by the velocity of waves within the base material.
My question is if i have a tubular or hollow part with a base material, does this count as a reduction of density compared to the base material of the tube or hollow part. Would the impedance of the material be reduced?
Then applying that same logic of tubular/hollowed parts to porous/cellular parts with the base material where the reduction of density can be just as extreme as the tubular/hollowed parts. Would the tubular/hollowed parts have relatively same impedance as the porous/cellular parts?
