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
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
