Transfer matrix analysis of a duct with gradually varying arbitrary cross-sectional areaa

A method is presented to determine the low-frequency sound field in a duct with a cross-section of arbitrary shape and area that varies gradually without discontinuities. The duct is modeled as several fictitious segments, each of which has a cross-sectional area that is a quadratic function of posi...
