The propagation of sound in elliptic ducts has been investigated as a model case to indicate the acoustic effects of departures from symmetry in a circular duct. The cut-off frequencies of the higher order circumferential modes in an elliptic duct have been calculated for various duct eccentricities

An investigation is made of the phase velocity of the sound wave propagating in a two-dimensional flexible duct that carries a uniform flow. The flexible duct considered herein is composed of two parallel, thin elastic plates. The outer surfaces of the duct are in contact with a stationary fluid med
