A second-order uniformly valid expansion is obtained by using the method of multiple scales for the 'non-linear wave propagation in a circular duct whose walls are lined with a non-linear acoustic material. The acoustic material is characterized by an empirical, non-linear impedance in which the ins

Many papers have been published on the subject of attenuation in lined ducts. One case for which results have not been published, however, and which is pertinent to several applications is that of a rectangular duct lined on all walls and containing a uniform flow. This is a relatively simple extens

It is well known that flanking sound transmission can affect the acoustic attenuation in ducts lined with dissipative material. The exact nature of the flanking paths, ''air-borne'' (sometimes termed ''radiation by-pass'') through ''breakout'' and subsequent ''breakin'' of sound through the duct wal
