A theoretical approach to sound propagation and radiation for ducts with suppressors [PDF]

The several phenomena involved in theoretical prediction of the far-field sound radiation attenuation from an acoustically lined duct were studied. These include absorption by the suppressor, termination reflections, and far-field radiation.
