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

This paper describes the development and application of a time-domain acoustic liner model which is suitable for the simulation of sound propagation and attenuation in lined ducts. The #uid #ow within the duct domain is represented by the non-linear, unsteady Euler equations while the liner model co

A theoretical model describing acoustic attenuation in a flexibile walled duct (having neither internal acoustic treatment nor external lagging) which passes through a reverberant space is described. This model is kept as simple as possible, consistent with retaining the salient physical features of
