Effect of cross-sectional area discontinuities in closed hard-walled ducts on frequency of longitudinal modes

A simple analytical method is developed to estimate frequencies of longitudinal modes in closed hard-walled ducts with discontinuities in a cross-sectional area. The approach adopted is based on a general expression for the acoustic impedance for a plane wave motion in a duct and conditions of imped...
