In aeronautic engineering, the ventilation noise is quite a problem for passager comfort. This study presents the acoustic waves propagation in acoustically lined tubes in the presence of mean flow. The aim of this work is to modelize the sound attenuation of reactive silencers in the case of circular or annular ducts.
