Transfer function method for measuring characteristic impedance and propagation constant of porous material

A method for measuring the characteristic impedance and propagation constant of porous materials is described. Measurements were performed based on a surface impedance method that required a set of distinct acoustic impedances derived at the material surface. This requirement is satisfied by arbitra...
