In section 2.6 a multimodal method of calculating
the input impedance and pressure field of a duct
from a known terminating radiation impedance matrix was presented.
In chapter 3 we went on to derive the expression for the
radiation impedance matrix of a cylindrical pipe terminated in an infinite
baffle. Now we will bring these together, reviewing the equations and giving
numerical results for the input impedance and pressure field for
an example object of cylindrical cross-section. The theoretical input
impedance calculated here will be compared to experimental results in the
following chapter.
