Abstract

An extension of the Wiener-Hopf technique is presented to investigate the effect of a very thin porous splitter or a rigid splitter on the sound attenuation in a duct. The results obtained by the present theory are compared with those obtained by the singularity method which supposedly has a disadvantage when the length of the splitter is large compared with the incident acoustic wave length.
